Abstract
BACKGROUND The optimal surgical strategy for pulmonary atresia with ventricular septal defect (PA/VSD) in neonates and young infants is controversial. Staged repair may be associated with a higher risk of inter-stage mortality, while primary repair may lead to frequent post-repair re-interventions. METHODS From 2004 to 2017, 65 patients with PA/VSD who underwent surgical intervention before 90 days of age were identified and enrolled in this retrospective study. The cohort was divided into two groups: group-SR, who underwent initial palliation with staged repair (n = 50), and group-PR who underwent primary repair (n = 15). RESULTS There were three post-palliation in-hospital mortalities, four inter-stage mortalities, and one post-repair in-hospital mortality in group-SR. In group-PR, there was one in-hospital death and one late death. Five-year survival rates were comparable between the two groups (group-SR: 83.6%; group-PR: 86.7%; p = 0.754). During the median follow-up duration of 44.7 months (Inter-quartile range, 19-109 months), 40 post-repair re-interventions (22 in group-SR, 18 in group-PR) were performed in 26 patients (18 in group-SR, 8 in group-PR). On Cox proportional hazards model, primary repair was identified as the only risk factor for decreased time to death/1st post-repair re-intervention (Hazard ratio (HR): 2.3, p = 0.049) and death/2nd post-repair re-intervention (HR 2.91, p = 0.033). CONCLUSIONS A staged repair strategy, compared with primary repair, was associated with comparable overall survival with less frequent re-interventions after repair in young infants with PA/VSD. Lowering the inter-stage mortality after initial palliation by vigilant outpatient care and aggressive home monitoring may be the key to better surgical outcomes in this subset. Surgical outcomes of PA with VSD according to the surgical strategies. Patient 1 (birth weight: 2.7 kg) underwent primary Rastelli-type repair at post-natal day # 50 (body weight: 3.8 kg) using Contegra® 12 mm. The postoperative course was rocky, with long ventilatory support (10 days), ICU stay (14 days), and hospital stay (20 days). Cardiac CT scan at 9 months post-repair showed severe branch pulmonary artery stenosis, which necessitated LPA stenting at 12 months post-repair and RV-PA conduit replacement with extensive pulmonary artery reconstruction at 25 months post-repair. Patient 2 (birth weight: 2.5 kg) underwent RMBT at post-natal day #30 (body weight: 3.4 kg) using 4 mm PTFE vascular graft and staged Rastelli-type repair at post-natal 11 months using a hand-made Gore-Tex valved conduit (14 mm). No post-repair re-intervention has been performed. Cardiac CT scan at 90 months post-repair showed no branch pulmonary artery stenosis.CT computed tomography, ICU intensive care unit, LPA left pulmonary artery, PA pulmonary atresia, PTFE polytetrafluoroethylene, RMBT right modified Blalock-Taussig shunt, RV-PA right ventricle to pulmonary artery, VSD ventricular septal defect.

Abstract
BACKGROUND Our institutional approach to tetralogy of Fallot with major aortopulmonary collateral arteries (MAPCAs) emphasizes early unifocalization and complete repair (CR). In the small subset of patients with dual-supply MAPCAs and confluent but hypoplastic central pulmonary arteries (PAs), our surgical approach is early creation of an aortopulmonary window (APW) to promote PA growth. Factors associated with successful progression to CR and mid-term outcomes have not been assessed. METHODS Clinical data were reviewed. PA diameters were measured offline from angiograms prior to APW and on follow-up catheterization >1 month after APW but prior to any additional surgical interventions. RESULTS From November 2001 to March 2018, 352 patients with tetralogy of Fallot/MAPCAs underwent initial surgery at our center, 40 of whom had a simple APW with or without ligation of MAPCAs as the first procedure (median age, 1.4 months). All PA diameters increased significantly on follow-up angiography. Ultimately, 35 patients underwent CR after APW. Nine of these patients (26%) underwent intermediate palliative operation between 5 and 39 months (median, 8 months) after APW. There were no early deaths. The cumulative incidence of CR was 65% 1 year post-APW and 87% at 3 years. Repaired patients were followed for a median of 4.2 years after repair; the median PA:aortic pressure ratio was 0.39 (range, 0.22 to 0.74). CONCLUSIONS Most patients with tetralogy of Fallot/MAPCAs and hypoplastic but normally arborizing PAs and dual-supply MAPCAs are able to undergo CR with low right ventricular pressure after APW early in life. Long-term outcomes were good, with acceptable PA pressures in most patients.

Abstract
OBJECTIVES Global and regional myocardial deformation have not been well described in fetuses with pulmonary atresia and intact ventricular septum (PA/IVS). Speckle-tracking echocardiography (STE), an angle-independent technique for assessing global and regional strain, may be a more sensitive way of determining ventricular systolic dysfunction compared with traditional 2D echocardiography. The aim of this study was to assess myocardial deformation in fetuses with PA/IVS compared with control fetuses and to determine if, in fetuses with PA/IVS, strain differs between those with and those without right ventricle-dependent coronary circulation (RVDCC). METHODS This was a retrospective analysis of fetuses with PA/IVS examined at two medical centers between June 2005 and October 2017. Left ventricular (LV) and right ventricular (RV) regional and global longitudinal strain (GLS) and strain rate were obtained using STE, and comparisons were made between fetuses with PA/IVS and gestational age (GA)-matched controls. Postnatal outcome was assessed, including the presence of RVDCC. RESULTS Fifty-seven fetuses with PA/IVS and 57 controls were analyzed at a mean GA of 26.5 ± 5 weeks. LV-GLS was significantly decreased in fetuses with PA/IVS compared with controls (-17.4 ± 1.7% vs -23.7 ± 2.0%, P < 0.001). LV strain rate was also significantly decreased (-1.01 ± 0.21/s vs -1.42 ± 0.20/s, P < 0.001). Fetuses with PA/IVS had decreased strain in all segments. Similarly, RV strain was significantly decreased in fetuses with PA/IVS (-11.6 ± 3.8% vs -24.6 ± 2.5%, P < 0.0001). Thirty-six patients had postnatal cardiac catheterization performed to define coronary anatomy; 10 fetuses had RVDCC. Fetuses with RVDCC had decreased LV strain compared with those without (-15.8 ± 1.2% vs -17.9 ± 1.7%, P = 0.009). RV strain was also decreased in fetuses with RVDCC vs those without (-7.0 ± 2.9% vs -12.1 ± 3.2%, P = 0.0004). CONCLUSIONS Fetuses with PA/IVS have decreased global and regional LV and RV strain compared with controls. The finding of decreased LV strain may be due to altered ventricular mechanics in the context of a hypertensive right ventricle and/or abnormal coronary perfusion. Moreover, fetuses that were found to have RVDCC postnatally had decreased LV and RV strain compared with those that did not. These results encourage further investigation to assess whether fetal ventricular strain could be a prenatal predictor of RVDCC. Copyright © 2018 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Transcatheter pulmonary valvuloplasty in neonates with pulmonary atresia and intact ventricular septum (PA-IVS) or duct-dependent pulmonary valve stenosis (DD-PVS) has become a reasonable alternative to surgical right ventricle decompression. AIM To investigate mid-term outcomes following pulmonary valvuloplasty. METHODS Sixty-five neonates with PA-IVS (n=29) or DD-PVS (n=36) (median age 4 days; mean weight 3.0kg) undergoing pulmonary valvuloplasty were reviewed retrospectively. Procedural data and clinical outcomes were assessed. RESULTS Pulmonary valvuloplasty was successful in 59 patients (90.8%). Preterm birth, larger tricuspid valve annulus diameter and PA-IVS correlated with procedural failure. Eleven patients (18.6%) required a Blalock-Taussig shunt during early follow-up, despite valvuloplasty. These neonates had smaller tricuspid and pulmonary valve annulus Z-scores (-1.9 vs. -0.8 [p=0.04] and -2.5 vs. -0.9 [P=0.005], respectively) and a higher incidence of "bipartite" right ventricle (P=0.02). Mean follow-up was 5.4±3.3 years. Mortality after successful valvuloplasty was 8.5% (n=5). Among the 54 survivors, biventricular repair was achieved in 52 patients (96.3%), including nine with a previous Blalock-Taussig shunt. The cumulative rate of subsequent surgery (excluding Blalock-Taussig shunt) was 13.7% (95% confidence interval 6.8-26.7%) and 16.4% (95% confidence interval 8.5-30.4%) at 2 and 4 years, respectively. Secondary surgery was significantly more frequent in PA-IVS compared with DD-PVS, and in neonates with a Blalock-Taussig shunt (P=0.003 and 0.01, respectively). CONCLUSIONS Selected neonates with DD-PVS or PA-IVS managed by transcatheter pulmonary valvuloplasty had a good mid-term outcome. In neonates with a borderline small right ventricle, a hybrid strategy with a supplementary source of pulmonary blood flow can be efficient to achieve biventricular repair.

Abstract
OBJECTIVE To assess the spectrum of associated anomalies, intrauterine course and outcome in fetuses with absent pulmonary valve syndrome (APVS). METHODS All cases with a prenatal diagnosis of APVS at two centers over a period of 13 years were analyzed retrospectively. APVS was diagnosed in the presence of rudimentary or dysplastic pulmonary valve leaflets with to-and-fro blood flow in the pulmonary trunk on color and pulsed-wave Doppler ultrasound. Data on demographic characteristics, presence of associated conditions, Doppler studies and pregnancy outcome were reviewed. RESULTS During the study period, 40 cases of APVS were diagnosed prenatally. Thirty-seven (92.5%) cases were associated with tetralogy of Fallot (TOF) and three (7.5%) had an intact ventricular septum. Patency of the ductus arteriosus (DA) was found in 17/37 (45.9%) TOF cases and in all three cases with an intact ventricular septum. Mean gestational age at diagnosis was 19.7 (range, 12-34) weeks with 10 (25.0%) cases (all with TOF) diagnosed in the first trimester. TOF was an isolated finding in 15 (37.5%) cases. Chromosomal anomalies, cardiac defects and extracardiac anomalies were present in 18 (45.0%), four (10.0%) and three (7.5%) cases, respectively. Among the 40 cases, there were 19 (47.5%) terminations of pregnancy, six (15.0%) intrauterine deaths, four (10.0%) neonatal deaths and 11 (27.5%) survivors. Patency of the DA, reversed flow during atrial contraction in the ductus venosus, umbilical artery or fetal middle cerebral artery, and hydrops/increased nuchal translucency thickness were significantly associated with non-survival. All 10 cases diagnosed in the first trimester had a patent DA and abnormal Doppler parameters, eight had hydrops and/or increased nuchal translucency, six were associated with trisomy 13 or 18 and none survived. CONCLUSION APVS diagnosed in the first trimester is significantly associated with TOF, patency of the DA, abnormal Doppler parameters, lethal trisomies and intrauterine mortality. Cases of APVS with isolated TOF and agenesis of the DA have a better outcome than those with additional anomalies, with > 80% survival. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
This article presents the 14-year experience of surgical treatment of pulmonary atresia with ventricular septal defect and pulmonary collateral blood bed. The surgery of defect was performed on 32 patients and they were followed up. The individual and differential approaches should be used in the choice of surgical strategy. This approach is based on the state of pulmonary arterial and collateral beds. An integral criterion of assessment was the common neo-pulmonary arterial index with boundary measure equal 150 mm2/m2. An application of given method allowed the performance of successful radical repair of defect in 15 patients, 4 patients having been operated in one stage. The rest of the patients had the appropriate staged interventions. The lethality consisted of 9.4%.

Abstract
OBJECTIVES Right ventricular sinus myectomy has been proposed for pulmonary atresia with intact ventricular septum for morphology falling within the uncertain area for eventual biventricular repair. Our objective was to evaluate right ventricular sinus myectomy by characterizing the morphologic spectrum of these patients, determining whether biventricular repair was achieved, ascertaining growth of right-sided structures, and assessing survival. METHODS We evaluated medical records, all imaging studies, and follow-up data (complete in all but 1 patient) from 43 patients with pulmonary atresia with intact ventricular septum treated from October 1993 to July 2005, 16 of whom underwent right ventricular sinus myectomy. Serial echocardiographic measurements of right-sided cardiac structures were converted to Z values to estimate their growth relative to somatic growth. RESULTS Patients undergoing right ventricular sinus myectomy had mild-to-moderate right ventricular size diminution (grade -1.2 +/- 3.2) and a tricuspid valve Z value of -4.9 +/- 1.9. Thirteen (87%) of the 16 patients achieved biventricular repair. After right ventricular sinus myectomy, mean right ventricular cavity size grade increased to 1.4 +/- 0.66, but the tricuspid valve Z value did not change appreciably over time. Five-year survival after sinus myectomy was 85%; late deaths were in patients with the smallest tricuspid valves at presentation (Z value < -7). CONCLUSIONS Right ventricular sinus myectomy in the uncertain area for biventricular repair of pulmonary atresia with intact ventricular septum leads to immediate increase in right ventricular volume. It, in combination with establishing right ventricle-pulmonary trunk continuity, allowed early biventricular repair in 87% of patients. However, tricuspid valve growth in relation to somatic growth was minimal. Thus, small tricuspid valve size might limit the long-term success of biventricular repair achieved by means of right ventricular sinus myectomy.

Abstract
OBJECTIVE This study analyzes whether small-diameter Contegras behave in the same way as small-diameter homografts, when implanted for the first time in pulmonary position. METHODS Small-diameter conduits include 12 and 14 mm Contegras and 8-14 mm homografts. Graft dysfunction is defined as right ventricular outflow tract obstruction with peak echo-Doppler gradient>40 mmHg, or grade III/IV graft regurgitation. Graft failure is defined as need for conduit replacement or need for catheter or surgical reintervention. Thirty-eight patients who received small Contegras (n=25) and small homografts (n=13) from October 2002 to end December 2006 were studied. The most frequent indication was pulmonary atresia and ventricular septal defect (n=20; 10 associated with major aorto-pulmonary collateral arteries), followed by truncus arteriosus (n=12). Most patients' characteristics were comparable except that recipients of homografts were smaller (p for body area=0.014). Survival, freedom from graft dysfunction, failure and explantation were estimated by the Kaplan-Meier method. The log-rank test was used to compare outcomes. RESULTS There were three early and four late deaths. No death was graft related. Survival was 80+/-8.2% for patients with Contegras and 77+/-11.7% for those with allografts: p=0.82. Mean follow-up duration is 22+/-16 months. Freedom from dysfunction for Contegras conduits decreased in the first 6 months and stabilized at 58+/-11% from month 14. For homografts it decreased only 1 year after implantation, down to 35+/-19.7% from month 31: p=0.61. Freedom from Contegras failure diminished the first 16 months to level out at 57+/-13%. No homograft failed the first 2 years. With a p-value of 0.14, homografts tended to fail less frequently. Five grafts were explanted. Freedom from explantation was similar (p=0.98): 90+/-6.7% for Contegras and 75+/-21.6% for homografts at year 3. CONCLUSION In the first 4 years after pulmonary implantation of small-diameter Contegras and homografts, the fate of both conduits was statistically similar, in spite of different behavior. As Contegras is 'off-the-shelf' available, it constitutes a sound alternative to homograft for right ventricular outflow tract reconstruction in neonates and infants.

Abstract
OBJECTIVE Our treatment strategy for pulmonary atresia with ventricular septal defect (VSD) and major aortopulmonary collateral arteries is a staged repair that comprises the first complete unifocalization (UF) with 'unification' of intrapulmonary arteries and then the definitive repair. The purpose of this study is to evaluate the outcome of our staged repair strategy with complete UF and to determine the results of our current management strategy. METHODS From 1982 to 2004, 113 consecutive patients were treated with staged repair at our institute. We evaluated the risk of definitive repair failure or death in the 3 years after definitive repair using logistic regression. Furthermore, we compared the early group (patients who underwent UF before December 1995) and the late group (patients who underwent UF after January 1996). RESULTS The mean follow-up interval was 8.8 years (0.8 months to 23.3 years), and Kaplan-Meier-estimated overall survival rates after first UF were 80.9, 73.8, and 69.9% at 5, 10, and 15 years, respectively. Survival in patients with an absent central pulmonary artery (PA) was significantly lower than in those with a central PA (p<0.05), and the factor that was significantly associated with definitive repair failure or death in the 3 years after definitive repair was central PA morphology (p<0.05). Higher mean PA pressure after UF was detected in patients with hypoplastic central PA, compared with those without hypoplastic PA (30.9 mmHg vs 23.3 mmHg, p<0.05). In the late group, age (in years) at first UF (3.9 vs 8.4, p<0.01), second UF (4.3 vs 9.2, p<0.01), and definitive repair (5.8 vs 9.1, p<0.01) was significantly younger than in early group, and the survival rate after first UF in the late group was 96.2 and 91.3% at 3 and 7 years, respectively. Systolic right ventricular pressure and the pressure ratio between the right and the left ventricles after definitive repair in the late group were significantly lower than in the early group (53.6 mmHg vs 75.0 mmHg, p<0.01; 61.7% vs 75.9%, p<0.05). CONCLUSIONS Hypoplastic central PA was a significant risk factor in this disease. The overall survival was improved by our current management strategy. Improved RV pressure after definitive repair appears to affect the long-term outcome.

Abstract
BACKGROUND The relatively high mortality in patients with pulmonary atresia and intact ventricular septum may be related to the presence of significant coronary arterial anomalies. This retrospective review of cineangiocardiograms was undertaken to further elucidate the types and variety of such coronary arterial abnormalities, and to assess their effect on postoperative survival. MATERIAL AND RESULTS Details regarding coronary arterial anatomy and abnormalities were assessed in 116 patients. We noted the site and severity of lesions, and the presence of fistulous communications from the right ventricle to the coronary arteries, assessing the proportion of left ventricular myocardium affected by coronary arterial interruptions or significant stenoses, in other words, the amount dependent on coronary circulation from the right ventricle. We also measured diameters of the tricuspid and mitral valves. Fistulas were found in 87 patients (75%), interruptions of major coronary arteries in 40 patients (34%), lack of connections between the coronary arteries and the aorta in 18 patients (16%), and single origin of a coronary artery, with the right coronary artery arising from the left, in 6 patients (5%). We found increased mortality in 47 patients (40%) who had a right ventricular-dependent coronary arterial circulation. The presence of fistulas in itself was not associated with higher mortality, but the presence of coronary arterial interruptions (p = 0.05), and a higher myocardial score (p = 0.0009), were. CONCLUSION We encountered a higher prevalence of both coronary arterial abnormalities and right ventricular-dependent circulation than previously reported. Awareness of the severity of the coronary arterial abnormalities should assist in planning treatment.

Abstract
BACKGROUND Pulmonary atresia with intact ventricular septum (PAIVS) has a wide spectrum of anatomic heterogeneity and invokes a wide variety of treatment strategies. We reviewed the outcome of our patients with PAIVS in order to delineate strategies for the optimal management of PAIVS. In particular, the possibility of avoiding neonatal surgical intervention with catheter-based technology was assessed. METHODS The study cohort was composed of all patients presented with PAIVS from January 1999 through December 2005. Demographic and anatomic variables were analyzed to determine association with in-hospital mortality. RESULTS Forty-four infants with PAIVS underwent catheter valvuloplasty (n = 17) and (or) surgical intervention (n = 42). The mean age and weight of the infants was six days and 3.1 kg, and the average follow-up was 40 +/- 29.5 months. Five (11%) had right ventricle dependent coronary circulation (RVDCC) and six (14%) had Ebstein's anomaly. Five (11%) patients died. Of those who underwent catheter valvotomy, three (18%) underwent shunt placement, 12 (71%) underwent right ventricular outflow tract reconstruction with shunt placement, and only two (12%) did not require a further surgical intervention in the newborn period. Multivariable analyses demonstrated RVDCC (odds ratio 21.3, p = 0.025) and Ebstein's anomaly (odds ratio 16.0, p = 0.038) to be risk factors for in-hospital mortality. Of those patients with Ebstein's anomaly, a single ventricle approach had a better outcome. CONCLUSIONS We demonstrated excellent recent outcomes for patients with PAIVS. Catheter-based interventions rarely avoid surgical repair. The RVDCC and Ebstein's anomaly were associated with high mortality. In patients with Ebstein's anomaly, single ventricular pathway may be the better strategy for this specific patient population.

Abstract
BACKGROUND Outcomes for pulmonary atresia with intact ventricular septum are suboptimal, while initial management remains controversial. This study was undertaken to determine the effect of catheter-based therapy on the need for early surgical intervention. METHODS A single-institution retrospective chart review was made of all 25 neonates with pulmonary atresia with intact ventricular septum from 1999 to 2005. RESULTS Mean age at first intervention was 3.1 +/- 2.2 days, mean weight 3.3 +/- 0.5 kg. Right ventricular hypoplasia varied: 20% normal, 16% mild, 28% moderate, 28% moderately severe or severe, 8% not classified. Median tricuspid valve z-score was -2.3 +/- 2.6. First intervention was catheter-based therapy in 56% (14 of 25), operative in 36% (9 of 25), and no therapy in 2. Technically adequate valvotomy was achieved in 79% (11 of 14). Serious catheter-related complications occurred in 3 of 14 (21%). Only 5 of 14 (36%) with catheter-based therapy weaned from prostaglandins without surgery. Of these, 2 required surgery for cyanosis at 1 and 3 months. Surgery after catheter-based therapy consisted of right ventricular outflow patch in 36% (4 of 11), systemic to pulmonary shunt in 64% (7 of 11). Median time between catheter-based therapy and surgery was 8.5 days (range, 1 to 89). Only 3 of the 23 treated patients avoided operation during infancy. There was 1 early and 1 late death after operation after initial catheter-based therapy, and 1 late death after primary surgery alone during a mean follow-up of 33 months (range, 1.5 to 79). CONCLUSIONS Balloon valvotomy alone for pulmonary atresia with intact ventricular septum rarely obviates the need for an additional source of pulmonary blood flow--either shunt or ductal stenting.

Abstract
OBJECTIVE Since a functional right ventricle is desirable when repairing pulmonary atresia with intact ventricular septum, we sought to determine the factors that portend a successful biventricular repair in these children. METHODS A review of operative records at UCLA between 1982 and 2001 revealed 56 patients diagnosed with pulmonary atresia with intact ventricular septum that underwent either a partial (n=26) or complete biventricular repair. Kaplan-Meier survival curves with log rank statistics were used to evaluate the influence of demographic, technical, and anatomic factors on survival and need for reoperation. RESULTS Five-year actuarial survival following biventricular repair was 91.5%. Non-Caucasian race (p=0.011) and omission of palliative right ventricular outflow tract obstruction (RVOTO) relief (p=0.042) were risk factors for early death. All patients with adequate follow-up required reoperation with median duration of 6.9 years. The most common cause of early reoperation (<1 year) was wound infection (35.3%) while pulmonary valve replacement (58.8%) constituted the majority of late reoperations. Risk factors for wound infection included female sex (p=0.011) and use of a synthetic transannular patch (p=0.085). The most significant risk factor for early pulmonary valve replacement was the use of a monocusp pericardial valve in the pulmonary annular position (p=0.003). CONCLUSIONS Excellent survival follows biventricular repair of pulmonary atresia with intact ventricular septum if RVOTO relief is performed in conjunction with initial palliation. Although most patients eventually require reoperation, avoidance of synthetic transannular patches and monocusp pericardial pulmonary valves may reduce the incidence of wound infection and delay need for pulmonary valve replacement.

Abstract
OBJECTIVES We described morphologic characteristics, particularly pulmonary anatomy, and determined the prevalence of definitive end states and their determinants in children with pulmonary atresia associated with ventricular septal defect (PAVSD). BACKGROUND Pulmonary atresia associated with ventricular septal defect represents a broad morphologic spectrum that greatly influences management and outcomes. METHODS From 1975 to 2004, 220 children with PAVSD presented to our institution. Blinded angiographic review (n = 171) characterized bronchopulmonary segment arterial supply. RESULTS A total of 185 patients underwent surgery, and repair was definitive in 75%. Initial operations included systemic-pulmonary artery shunt in 57%, complete primary repair in 31%, or right ventricular outflow tract reconstruction in 12%. Based on angiographic review, 118 patients had simple PAVSD and 53 patients had PAVSD with major aortopulmonary collateral arteries (MAPCAs). Overall survival from initial operation was 71% at 10 years. Risk factors for death after initial operation included younger age at repair, earlier birth cohort, fewer bronchopulmonary segments supplied by native pulmonary arteries, and initial placement of a systemic-pulmonary artery shunt. Competing-risks analysis for initially palliated patients predicted that after 10 years, 68% achieved complete repair (with associated factors including later birth cohort and more bronchopulmonary segments supplied by native pulmonary arteries), 22% died without repair, and 10% remained alive without repair. Reoperations after complete repair occurred in 38 children (27%), with risk factors including older age at palliation, MAPCAs, and more segments supplied by collaterals. CONCLUSIONS Outcomes in children with PAVSD have improved over time, and are better in completely repaired cases. Bronchopulmonary arterial supply is an important determinant of mortality, achievement of definitive repair, and post-repair reoperation.

Abstract
OBJECTIVES Pulmonary atresia with intact ventricular septum is a form of congenital heart disease usually associated with right-heart hypoplasia, with considerable morphologic heterogeneity and often poor outlook. Ascertainment of risk factors for poor outcome is an important step if an improvement in outcome is to be achieved. METHODS The UK and Ireland Collaborative study of Pulmonary Atresia with Intact Ventricular Septum is an ongoing population-based study of all patients born with this disease from 1991 through 1995. All available clinical, morphologic, and investigative variables were directly reviewed, and risk factor analysis was performed for poor outcome. RESULTS One hundred eighty-three patients presented with pulmonary atresia with intact ventricular septum. Fifteen underwent no procedure, and all died. Of the remainder, 67 underwent a right ventricular outflow tract procedure (catheter or surgical), 18 underwent an outflow tract procedure with shunt, and 81 underwent a systemic-to-pulmonary shunt alone. One- and 5-year survival was 70.8% and 63.8%, respectively. Results from Cox proportional hazards model analysis showed that low birth weight (P = .024), unipartite right ventricular morphology (P = .001), and the presence of a dilated right ventricle (P < .001) were independent risk factors for death. The presence of coronary artery fistulae, right ventricular dependence, or the tricuspid valvar z score did not prove to be risk factors for death. After up to 9 years of follow-up, 29% have achieved a biventricular repair, 3% a so-called one-and-a-half ventricular repair, and 10.5% a univentricular repair, with 16.5% still having a mixed circulation (41% died). CONCLUSIONS This population-based study has shown which features at presentation place an infant in a high-risk group. This is important information for counseling in fetal life and for surgical strategy after birth.

Abstract
OBJECTIVE To identify the surgical approaches and risk factors which influence longevity of right ventricle to pulmonary artery (RV-PA) conduits following first reoperation for obstruction. METHODS Between January 1993 and August 2003, 114 patients underwent 141 reoperations for RV-PA conduit obstruction. Diagnoses included 'Truncus Arteriosus' (n=52), 'Pulmonary atresia/Tetralogy of fallot' (n=39), 'Double outlet right ventricle' (n=10), 'Transposition of great arteries, VSD, and pulmonary atresia' (n=9), and the 'Ross operation' (n=4). All patients had undergone a previous biventricular repair. The first reoperation for conduit obstruction was performed in 112 hospital survivors by: total conduit replacement (Group A, n=73) with valved (homograft=10 and xenograft=54) or non-valved (n=9) conduit, and patch enlargement of the obstructed RV outflow tract with preservation of the posterior and sides of the conduit wall after removing of the fibrocalcific peel and degenerated valve (Group B, n=39). Mean age at first reoperation was 8.8+/-6.7 and 7.5+/-5.3 years in patients of groups A and B, respectively. Seven patients in Group A and 18 in Group B required a second reoperation and two patients in Group B a third reoperation. RESULTS There were two hospital deaths and no late deaths. Mean follow-up was 5.8+/-3.2 years. Risk factors for second reoperation by univariate analysis were: homograft conduit use (P=0.004), Group B surgical approach (P=0.0001), higher RV-PA systolic pressure gradient at discharge (P=0.02), and age <5-years-old (P=0.01). Multivariate analysis showed that inclusion in Group B and younger age (<5-years-old) at repair were independent risk factors for second reoperation. Group B surgical approaches had higher RV-PA systolic pressure gradient at discharge (P=0.02) and required more PA bifurcation repair at the time of second reoperation (P=0.05). Freedom from second reoperation for conduit obstruction was significantly higher in Group A patients at 5 and 8 years (P<0.04) and those with xenografts rather than homograft (P=0.04). CONCLUSIONS Our results support the optimal surgical approach for RV-PA conduit obstruction is total replacement with a xenograft. RV outflow reconstruction by other techniques without complete dissection of PA bifurcation does not completely relieve the stenosis and could cause early restenosis. Higher systolic gradients at discharge and younger age at first reoperation are predictors of earlier reoperation.

Abstract
OBJECTIVE Aortic regurgitation (AR) in the tetralogy of Fallot (TOF) is not frequent, but when present it impacts significantly on surgical management. Furthermore, the incidence of late AR development has been increasing, along with surgical interest in current practices. METHODS Pre- and post-operative studies on 427 patients (TOF, 374; TOF/PA (TOF with pulmonary atresia), 53) who survived corrective operation were reviewed. AR (> or =mild) was detected in 28. RESULTS Nine had AR preoperatively, while 25 (including six with preoperative AR) exhibited AR post-operatively. In the 19 who developed AR post-operatively, the aortic root diameter (AoRoD) and indexed AoRoD (%AoRoD) were 42+/-11 mm and 166+/-36%, increased from the preoperative values of 30+/-10mm and 149+/-24%. AR-free rate at 20 years was 95.1% of all cases studied, 84.3 vs 96.5% in TOF/PA vs classic TOF (P<0.0001), and 82.2 vs 97.0% in bulboventricular VSD vs infracristal VSD (P<0.0001). Older age at repair, and bulboventricular VSD were identified as risk factors for the progression of AR. Aortic valvuloplasty (AVP; n=5) or replacement (AVR; n=4) was performed nine times in eight patients before (n=1), during (n=4), or late after TOF repair (n=4); all showed improvement of NYHA class. Survival- and reoperation-free survival curves showed no significant difference between patients with or without AR. CONCLUSIONS After repair of TOF, careful observation for a late progression of AR is needed for the optimal timing of surgical intervention, especially in patients who repaired at higher age with a dilated aortic root or in patients with bulboventricular VSD.

Abstract
BACKGROUND Recent work has focused attention on interim mortality (death after hospital discharge and before second-stage surgery) in hypoplastic left heart syndrome. This study investigates interim mortality in infants undergoing systemic-to-pulmonary artery shunts for pulmonary atresia with intact ventricular septum. METHODS At two centers in 11 years (January 1991 through December 2001), 35 infants underwent placement of shunts for palliation of pulmonary atresia with intact septum. Patients were identified from the cardiology database at each institution, and data were collected retrospectively. The infants were classified into two groups, with and without severe right ventricular hypoplasia, based on the initial surgical plan (Fontan or two-ventricle repair). RESULTS The mean age and weight of the infants were 9 days and 3.1 kg. The right ventricle was severely hypoplastic in 22 of 35 infants. Hospital death occurred in 2 patients (9.1%), 1 with severe right ventricular hypoplasia. The remaining 33 patients form the study population. There were a total of 5 deaths (15%) after discharge and before second-stage operation, all in patients with severe right ventricular hypoplasia. Two patients, 1 with hypoplastic right ventricle, died after second-stage operation. CONCLUSIONS These data confirm a significant incidence of interim death in infants with pulmonary atresia and hypoplastic right ventricle. The interim mortality rate in the current two-institution study of infants with pulmonary atresia with intact ventricular septum is similar to that in hypoplastic left heart syndrome if all patients are considered (15%), and is somewhat higher (24%) than that for hypoplastic left heart syndrome if only patients with severe right ventricular hypoplasia are considered. This rate of interim death must be considered when different treatment options (such as shunt or transplant) are contemplated.

Abstract
OBJECTIVES We sought to determine trends, and outcomes, for a cohort of patients with pulmonary atresia with intact ventricular septum born between 1965 and 1998. BACKGROUND Pulmonary atresia with intact ventricular septum is a complex lesion that remains a therapeutic challenge, particularly regarding the suitability for biventricular repair. METHODS We identified 210 consecutive patients, and reviewed their medical records, initial angiograms, and echocardiograms, along with the relevant surgical and pathology reports. RESULTS The mean initial Z-score for the diameter of the tricuspid valve was -0.99 +/- 1.95, with Ebstein's malformation in 8%. A right ventricular dependent coronary arterial circulation was found in 23%. The proportion of patients who received treatment increased over time, although placement of an arterial shunt was the predominant initial procedure throughout the experience. At the last follow-up, 107 patients had not reached the planned final stage of their repair, and 79% of these had died. Of the 103 reaching the final stage of planned repair, 58 had undergone attempted biventricular repair, with 34% dying; 14 had undergone attempted one and a half ventricular repair, with 7% dying, and 31 had undergone attempted functionally univentricular repair, with 10% dying. Overall, survival was 57% at the age of 1 year, 48% at 5 years, and 43% at 10 years. Survival improved over time, with survival of 75% at 1 year, and 67% at 5 years, for patients born between 1992 and 1998. An earlier date of birth, the presence of Ebstein's malformation, and prematurity were all significant independent factors associated with decreased survival. A greater severity of coronary arterial abnormalities was significantly associated with a greater likelihood of left ventricular dysfunction during follow-up. CONCLUSIONS The outcomes for patients born with pulmonary atresia with intact ventricular septum have improved over time, albeit that careful initial management, and better selection, is still indicated for those planned to undergo biventricular repair.

Abstract
OBJECTIVE We sought to define the prevalence of definitive end states and their determinants in children given a diagnosis of pulmonary atresia and intact ventricular septum during the neonatal period. METHODS Between 1987 and 1997, 408 neonates with pulmonary atresia and intact ventricular septum were entered into a prospective study by 33 institutions. Competing risks analysis was used to demonstrate the prevalence of 6 end states. Factors predictive of attaining each end state were identified by means of multivariable analysis with bootstrap validation. RESULTS Overall survival was 77% at 1 month, 70% at 6 months, 60% at 5 years, and 58% at 15 years. Prevalence of end states 15 years after entry were as follows: 2-ventricle repair, 33%; Fontan repair, 20%; 1.5-ventricle repair, 5%; heart transplant, 2%; death before reaching definitive repair, 38%; and alive without definitive repair, 2%. Patient-related factors discriminating among end states primarily included adequacy of right-sided heart structures, degree of aberration of coronary circulation, low birth weight, and tricuspid valve regurgitation. After adjusting for these factors, 2 institutions were predictive of 2-ventricle repair, 1 of Fontan repair, and 6 of death before definitive repair. Two institutions were predictive of both 2-ventricle and Fontan repair. These 2 institutions achieved a higher risk-adjusted prevalence of definitive repair and a lower prevalence of prerepair mortality. CONCLUSIONS Characteristics of neonates with pulmonary atresia and intact ventricular septum predict type of definitive repair. A morphologically driven institutional protocol emphasizing both 2-ventricle and Fontan pathways might mitigate the negative effect of unfavorable morphology. In the current era, 85% of neonates are likely to reach a definitive surgical end point, with 2-ventricle repair achieved in an estimated 50%.

Abstract
Pulmonary atresia with ventricular septal defect (PAVSD) is a complex cardiopathy represented by a complete obstruction between the right ventricle outflow and the pulmonary trunk associated with a ventricular septal defect (VSD) and major aortopulmonary collaterals (MAPCA). The goal of the unifocalization in the PAVSD is to prepare the pulmonary tree for the complete repair by connecting the MAPCAs to the central pulmonary arteries that should be enlarged. After that we can made the VSD or other intracardiac repair. This is a retrospective study on 31 patients. We report our results discussing the PAVSD classification and the strategy of the complete repair in comparison with other reported results.

Abstract
OBJECTIVES The purpose of this study was to examine the safety and efficacy of interventional catheterization performed early after congenital heart surgery. BACKGROUND Transcatheter interventions performed in the early postoperative period are viewed as high risk. To date, there have been limited published data regarding these procedures. METHODS All catheterizations performed within six weeks after congenital heart surgery between August 1995 and January 2001 were retrospectively reviewed. A cardiac anesthesiologist, cardiac intensivist, cardiac surgeon, and operating room team were available for all cases. Interventional procedures were performed based on clinical indications, regardless of the time elapsed from surgery. RESULTS Sixty-two patients, median age four months (2 days to 11 years), weight 4.7 kg (2.3 to 45 kg), underwent 66 catheterizations on median postoperative day 9 (0 to 42 days). Thirty-five cases involved 50 interventional procedures. Nine patients required extracorporeal cardiopulmonary support. Success rates by procedure were: angioplasty, 100%; stent implantation, 87%; vascular/septal occlusion, 100%; and palliative pulmonary valvotomy, 75%. Complications included stent migration (one patient), cerebral vascular injury (one patient), and left pulmonary artery stenosis (one patient). Thirty procedures involved angioplasty or stent implantation, including 26 involving a recently created suture line. Suture disruption or trans-mural vascular tears were not observed. There was no procedural mortality. Thirty-day survival for patients undergoing intervention was 83%. CONCLUSIONS Transcatheter interventions can be successfully performed in the early postoperative period. These procedures can have a positive impact on patient outcome; however, they should be performed only by a pediatric interventional cardiologist supported by a multi-disciplinary team.

Abstract
BACKGROUND The 22q11.2 deletion (del22q) is present in many patients with conotruncal abnormalities including pulmonary atresia with ventricular septal defect (PA/VSD). We sought to determine the impact of the del22q on outcome in subjects with PA/VSD. METHODS We reviewed the experience for all patients with PA/VSD who were born between January 1993 and April 2002 and presented to our institution. Patients with conotruncal defects were routinely evaluated for genetic disorders including del22q. Fluorescence in situ hybridization was used to test for del22q. RESULTS There were 67 subjects with PA/VSD who presented during that time period; testing for del22q was performed in 58 of 67 (87%) and these 58 patients comprised the study population. The 22q11.2 deletion was present in 20 of 58 (34%) patients tested. Major aortopulmonary collaterals were defined by angiography and were present in 27 (47%). These collaterals were significantly more common among subjects with del22q (13 of 20, 65%; p = 0.04). The median cross sectional area of the pulmonary arteries, the Nakata index, was significantly less for patients with del22q (41 versus 142 mm(2)/m(2); p = 0.006). There were 3 subjects, all of whom had del22q, who did not undergo surgery owing to markedly hypoplastic pulmonary arteries. Of the remaining 55 patients, 53 had arteriopulmonary shunt with or without unifocalization as the initial procedure and 35 patients have undergone complete repair. There were 8 operative deaths and 1 nonoperative death. The 5-year survival was 36% for patients with del22q versus 90% for patients without del22q. The 22q11.2 deletion was a significant risk factor for death, even after adjusting for the presence of major aortopulmonary collaterals (p = 0.004). There was no significant difference between the two groups with respect to the incidence of serious viral, bacterial, or fungal infections in the perioperative period. CONCLUSIONS Patients with del22q and PA/VSD are at increased risk for death owing to a variety of factors including less favorable pulmonary artery anatomy. A better understanding of del22q, pulmonary artery anatomy, and outcome is required.

Abstract
OBJECTIVES We evaluated the long-term results of perforation of the pulmonary valve in patients with pulmonary atresia with an intact ventricular septum (PA-IVS). BACKGROUND Interventional perforation of the pulmonary valve is considered the elective first stage treatment for PA-IVS, particularly in patients with a tripartite right ventricle (RV) and normal coronary circulation. However, the long-term results of this procedure are lacking. METHODS Between January 1991 and December 2001, 39 newborns with a favorable form of PA-IVS underwent attempted perforation of the pulmonary valve. We evaluated the early and long-term outcomes. RESULTS Median tricuspid and pulmonary z values were -1.2 and -2.4, respectively. Perforation was successful in 33 patients. Among them, 17 needed neonatal surgery, 13 did not need any surgery, and 3 had elective surgery after the first month of life. There were two procedure-related deaths, seven nonfatal procedural complications, and four postsurgical deaths. Compared with patients needing neonatal surgery, those having no or elective surgery had a higher incidence of a tripartite RV and a higher median tricuspid z value (92% vs. 53%, p = 0.04 and -1.7 vs. -0.5, p = 0.03). At a median follow-up of 5.5 years (range 0.5 to 11.5), survival was 85% and freedom from surgery was 35%. Five patients, four of whom had neonatal surgery, underwent a partial cavo-pulmonary connection. CONCLUSIONS Our results show that this technique, although burdened by non-negligible mortality and morbidity, is effective in selected patients with a normal-sized RV. Preselection of patients allows interventional or surgical biventricular correction in the majority of cases.

Abstract
OBJECTIVE This study was designed to determine whether either of 2 alternative methods of extracardiac Fontan reconstruction provides superior results. METHODS We reviewed 58 consecutive Fontan procedures performed between 1995 and 2001 with a pedicled pericardial tunnel (group P, n = 21) or an extracardiac conduit of polytetrafluoroethylene or allograft aorta (group C, n = 37). Operations were performed with cardiopulmonary bypass at 32 degrees C; an aortic crossclamp was applied in only 6 patients. All group P patients and 33 (89%) group C patients received fenestrations. RESULTS The groups were similar in terms of age, weight, anatomy, and preoperative hemodynamics. There were 3 hospital deaths (5%; 70% confidence limit, 2%-30%), all in group C. Median durations of mechanical ventilation (group P, 1 day; group C, 1 day), intensive care unit stay (group P, 3 days; group C, 3 days), chest tube drainage (group P, 8 days; group C, 7 days), and hospitalization (group P, 10 days; group C, 9 days) were not significantly different. There were no late deaths. All patients received warfarin sodium, and there were no late strokes. Before the Fontan procedure, 1 patient in group P and 3 patients in group C required pacemaker implants. Of the 51 surviving patients in sinus rhythm before the Fontan procedure, only 1 patient in group C subsequently required a pacemaker. CONCLUSIONS Extracardiac Fontan procedures with either a pericardial baffle or conduit are associated with low operative mortality and low risks of arrhythmia and late thromboembolic complication.

Abstract
We reported echocardiographic findings and outcomes of fetuses with absent pulmonary valve syndrome diagnosed during fetal life. Cases were identified from a prospectively acquired computerized database of 18,308 pregnancies referred to a fetal cardiology center between January 1988 and July 2000. Twenty fetuses were identified with a median gestation of 23 weeks (range 18 to 36) at presentation. In 18 cases (90%), there was an associated ventricular septal defect. Eighteen cases (90%) had branch pulmonary artery diameters above the normal range. In four cases (20%), an arterial duct was present. A chromosome 22q11 deletion was identified in 2 of 9 cases (22%) in which this deletion was sought. There were 6 terminations of pregnancy (30%), 3 intrauterine deaths (15%), 5 neonatal deaths (25%), 3 infant deaths (15%), and 3 patients who did not die (15%). Ten of the 11 "liveborn" infants required early ventilation. The outcome of absent pulmonary valve syndrome diagnosed prenatally appears poor. The high morbidity and mortality is due to both cardiac disease and associated bronchomalacia.

Abstract
OBJECTIVE We sought to determine the results of surgical treatment of patients with tetralogy of Fallot and pulmonary atresia with or without major aortopulmonary collateral arteries, to clarify variables affecting early and late mortality, and to expose late, nonfatal events affecting surgical patients. METHODS The records of 495 patients operated on from 1977 to 1999 were reviewed. Patients were separated into those who did not undergo complete repair (group A) and those who did (group B). RESULTS Group A consisted of 160 patients. Eighty-one (51%) had palliative procedures, 45 (28%) had preliminary surgical stages (unifocalization and right ventricular outflow tract reconstruction) as initial operations, and 34 (21%) had all surgical stages but were rejected for complete repair. Early and late mortality were 16.3% (n = 26) and 23.1% (n = 31), respectively. Mean follow-up was 72.3 months. The presence of major aortopulmonary collateral arteries was a risk factor for late mortality (P =.0182). Group B consisted of 335 patients. Mean age at complete repair was 11.3 years (SD, 9.2). One hundred three (30%) patients had single-stage complete repair, whereas 232 (69%) had staged reconstruction. Twenty-two (6.6%) patients underwent reopening of the ventricular septal defect for high right ventricular pressure. Early and late mortality were 4.5% (n = 15). Risk factors were a peak right ventricular/left ventricular pressure ratio of greater than 0.7 and reopening of the ventricular septal defect (P < or = .05). Late mortality was 16% (n = 51). Mean follow-up was 11.4 years (SD, 7.5). Risk factors included male sex, nonconfluent central pulmonary arteries, reopening of the ventricular septal defect, and postrepair conduit exchange (n = 137). Ten- and 20-year results were an actuarial survival of 86% and 75% and freedom from reoperation of 55% and 29%, respectively. CONCLUSIONS Surgical repair of patients with simple or complex forms of tetralogy of Fallot with pulmonary atresia can be achieved with low early mortality. Late mortality and need for reoperation, especially conduit replacement, continue to affect the long-term well-being of these patients.

Abstract
BACKGROUND In the Fontan procedures total cavopulmonary connection with an extracardiac conduit is a concern. The potential benefits of an extracardiac conduit may be the avoidance of postoperative supraventricular arrhythmias over the long-term, hemodynamic benefits due to laminar flow, possibility of completion without anoxic arrest, and applicability to anomalous systemic or pulmonary venous return, or both anomalous systemic and pulmonary venous return. We demonstrate early to midterm results of total cavopulmonary connection with an extracardiac conduit. METHODS Between March 1994 and February 2000, a total of 100 patients underwent total cavopulmonary connection with an extracardiac conduit. In 27 patients, who underwent a single stage total cavopulmonary connection operation, 7 were done without palliation. Seventy-three patients had undergone a bidirectional Glenn shunt before completion of the total cavopulmonary connection. We used an expanded polytetrafluoroethylene tube graft as the extracardiac conduit. RESULTS Cardiopulmonary bypass time was 133.2+/-55.2 minutes. Myocardial ischemic time was 38.5+/-23.2 minutes in 40 patients who needed cardioplegic cardiac arrest for intracardiac procedures. Intraoperative fenestration was done in only 1 patient. There were no operative deaths. During follow-up of 37.3 months, there were 5 late deaths. When compared with the patients treated by the lateral tunnel technique in our institute, there was no significant difference in actuarial survival rate, but the event free rate of the extracardiac conduit group was significantly superior to the lateral tunnel group. CONCLUSIONS Total cavopulmonary connection with the extracardiac conduit produced good results in short to midterm follow-up.

Abstract
OBJECTIVE To investigate mortality, cause of death, survival, and quality of life in all types of cardiac malformation with congenital pulmonary atresia. DESIGN Retrospective analysis. SETTING The resident population of one health region with a single tertiary referral centre. PATIENTS All babies with pulmonary atresia live born in 1980 to 1995. MAIN OUTCOME MEASURES Anatomical classification, total mortality, cause of death, duration of survival, exercise ability. All cases were classified as pulmonary atresia with intact septum (PA-IVS), pulmonary atresia with ventricular septal defect (PA-VSD), or pulmonary atresia with complex cardiac malformation (complex pulmonary atresia). RESULTS 129 cardiac malformations with congenital pulmonary atresia were identified from 601 635 live births (21.4/100 000): 29 had PA-IVS, 60 had PA-VSD, and 40 had complex pulmonary atresia. Total mortality was 72/129 (56%), with 15 deaths in the first week and 49 in the first year. There were 23 surgical deaths, 33 hospital deaths (not related to surgery), and 16 sudden deaths, 12 of which remained unexplained. The sudden death rate was 29/1000 patient years of follow up. Of the 57 survivors, 39% have exercise ability I or II and 61% III or IV. Definitive surgical repair produced better exercise ability. CONCLUSIONS Early mortality is high in all types of pulmonary atresia, although survival has improved in recent years. Most children who have not undergone definitive repair have significant exercise limitation.

Abstract
OBJECTIVE We compared the result of radiofrequency (RF)-assisted valvotomy and balloon dilation with closed surgical valvotomy and Blalock Taussig (BT) shunt as primary treatment in selected patients with pulmonary atresia and intact ventricular septum (PA-IVS). BACKGROUND Patients with PA-IVS who have mild to moderate hypoplasia of the right ventricle (RV) and patent infundibulum have the greatest potential for complete biventricular circulation. The use of RF or laser wires to perforate the atretic valve followed by balloon dilation provides an alternative to surgery. METHODS Between May 1990 and March 1998, 33 selected patients underwent either percutaneous RF valvotomy and balloon dilation (group 1, n = 21; two crossed over to group 2) or surgical valvotomy with concomitant BT shunt (group 2, n = 14). Second RV decompression by balloon dilation or right ventricular outflow tract (RVOT) reconstruction were performed if necessary. Patients who remained cyanosed were subjected to transcatheter trial closure of the interatrial communication. Partial biventricular repair was offered to those with inadequate growth of the RV. RESULTS The primary procedure was successful in 19 patients in group 1. There was one in-hospital death and two late deaths. Of the remaining 16 survivors, 12 achieved complete biventricular circulation, 7 of whom required no further interventions. Two patients required repeat balloon dilation, 1 RVOT reconstruction and 2 transcatheter closure of interatrial communication. Two patients underwent partial biventricular repair. In group 2, there were 3 in-hospital deaths after the primary procedure and 1 patient died four months later. All survivors (n = 10) required a second RV decompression, 8 by balloon dilation and 2 by RVOT reconstruction, after which, two patients died. Of the final 8 survivors, 7 achieved complete biventricular circulation, 5 after coil occlusion of the BT shunt and 2 after closure of interatrial communication. CONCLUSIONS Radiofrequency valvotomy and balloon dilation is more efficacious and safe compared with closed pulmonary valvotomy and BT shunt in selected patients with PA-IVS.

Abstract
The results of transcatheter valvotomy in pulmonary atresia with intact ventricular septum (PA-IVS) patients are presented with an attempt to identify the predictive factors for pulmonary valvotomy alone as definitive treatment. Between June 1995 and December 1997, 14 PA-IVS neonates with tripartite right ventricle underwent an attempted pulmonary valvotomy. For perforation of the pulmonary valve, a guidewire was used in 4, and a radiofrequency guidewire in 10 patients. Two outcome groups were identified. Group I included those in whom transcatheter treatment achieved a definitive success; group II patients required surgery despite an initial successful valvotomy. The attempt failed in 3 patients, 1 of whom had pericardial effusion. Perforation of the pulmonary valve was achieved in 11 patients: 2 with a guidewire and 9 with a radiofrequency guidewire. A subsequent balloon valvuloplasty was performed in these 11 patients. After valvuloplasty, mean right ventricular pressure decreased from 124 +/- 24 to 60 +/- 15 mm Hg (p <0.01). One died of heart failure and infection 10 days later, despite successful weaning from prostaglandin E1. Group I patients (n = 6) were treated with transcatheter valvotomy alone. Group II patients (n = 4) required right ventricular outflow patch. Significant differences between the 2 groups (group I vs II) were identified in tricuspid valve Z value (0.52 +/- 0.37 vs -1.25 +/- 0.48, p <0.05), pulmonary valve Z value (-3.47 +/- 0.59 vs -5.43 +/- 0.94, p <0.05), and ratio of right-to-left ventricular area on the apical 4-chamber view (0.73 +/- 0.06 vs 0.49 +/- 0.03, p <0.05). There were no significant differences in hemodynamic characteristics between the 2 groups. After a follow-up period ranging from 7 to 35 months (mean 18 +/- 10.3), the most recent echocardiograms in the 10 patients showed a mean pressure gradient across the pulmonary valve of 17 +/- 15 mm Hg. All 10 patients had an oxygen saturation of >92%. Transcatheter valvotomy using a radiofrequency guidewire is a safe and effective treatment in selected patients with PA-IVS. Transcatheter valvotomy can be a definitive treatment in PA-IVS patients with a tricuspid valve Z value > or = -0.1, pulmonary valve Z value > or = -4.1 and ratio of right-to-left ventricular area > or = 0.65.

Abstract
OBJECTIVE From October 1989 to June 1998, 60 patients have undergone the Norwood procedure (stage I) at our institution. The results of the staged surgical reconstruction and risk factors were analysed. Typical hypoplastic left heart syndrome (HLHS) and complex lesions with aortic hypoplasia were compared with each other. PATIENTS Typical HLHS: N = 48, median age 15 days (5-190 days), median weight 3.6 kg (2.6-5.3 kg). Complex lesions (dominant left ventricle): N = 12, median age 59 days (10-884 days), median weight 3.4 kg (2.4-12 kg). RESULTS Typical HLHS: The stage-I hospital survival was 73% (35/48). It improved from 60% (95% confidence interval: 49-71%) during 1989-1994 to 91% (95% CI: 81-100%) during 1997-1998. Seven patients were lost late. The right ventricular end diastolic diameter (P = 0.015), shortening fraction (P = 0.027), and the presence of an obstructed pulmonary venous return (P = 0.0032) were significant risk factors. 23 children underwent stage-II operation with four (17%) deaths. All survivors experienced an improvement of their statomotoric development. Stage-III operation was performed in 13 patients with no hospital death. Follow up after stage-III procedure was 7 months to 7 years. 4 year actuarial survival, including hospital mortality and deaths at subsequent stages, improved from 28% (95% CI: 18-38%) during 1989-1994 to 58% (95% CI: 48-68%) during 1994-1997. No patient had signs of myocardial insufficiency. Complex lesions: Stage-I hospital survival was 83% (10/12) with no late death. Stage-II was performed in 8 and stage-III in 6 patients with no death respectively. CONCLUSION In typical HLHS the results have improved over time. Both size and function of the right ventricle determined significantly stage-I survival. An early operation prevents the natural progression of pulmonary blood flow and may weaken all three risk factors. Patients with complex lesions seemed to have better chances of surviving the early postoperative period. The multistage reconstructions have become a realistic option for patients with HLHS and similar lesions, regardless of the morphologic subtype or diminutiveness of the aorta, and lead to an acceptable quality of life.

Abstract
OBJECTIVE Pulmonary atresia with intact ventricular septum is an anatomically heterogeneous anomaly with a variety of surgical strategies possible. We sought to compare the outcome of patients with a single ventricle approach to those with a biventricular repair and to compare outcome of patients with coronary abnormalities to those with normal coronary arteries. METHODS A retrospective review of our surgical database revealed 67 patients with pulmonary atresia with intact ventricular septum operated on between 1981 and 1998. Patients were categorized on the basis of initial surgical strategy: strategy A, aortopulmonary shunt alone (n = 31); strategy B, right ventricular recruitment (n = 32); strategy C, heart transplantation (n = 4). Tricuspid valve size (Z-score) and coronary anatomy were determined. Right ventricular-coronary artery dependency was noted in 8 patients. RESULTS Overall actuarial survivals at 1, 5, and 8 years were 82%, 76%, and 76%. Mortality was highest in infancy (10 of 16 deaths). Outcome was equivalent for all 3 strategies. There was no difference in tricuspid valve size between survivors and nonsurvivors (mean Z-score -2.0 (2.5) vs -2.0 (1.9), P =.83). There was no difference in survival based on severity of coronary abnormality. Only one third of patients had a successful biventricular repair, and the tricuspid valve was significantly larger in these than in patients who had Fontan operation (mean Z-score -0.53 [1.6], range -3.5 to 1, versus mean Z-score -3.03 [2.7], range -5.5 to 0, P =.002). CONCLUSIONS Surgical outcome for patients born with pulmonary atresia with intact ventricular septum is satisfactory. The strategies of biventricular repair, single ventricle palliation, and heart transplantation allow for equal outcome among all anatomic subtypes.

Abstract
AIMS Little is known about the medium term results after stenting of the arterial duct in neonates and infants with duct-dependent cyanotic congenital heart disease. We report the results of stent implantation of the arterial duct in 21 neonates and infants. The defects for which the arterial duct was stented included pulmonary atresia with intact ventricular septum, critical pulmonary stenosis, and more complex defects with associated reduced pulmonary blood flow. METHODS AND RESULTS Palmaz stents were used and successfully implanted in all the 21 patients. There were no major complications during the stent implantation procedure although two hospital deaths occurred 2 and 14 days after stent implantation. Cardiac catheterization was repeated electively 3 to 6 months after stent implantation. Stent stenosis due to intimal proliferation was noted in 11/13 patients who underwent recatheterization. Stenosis of the inner stent lumen ranged from 25% to 100%, mean 74%. Re-dilatation of the stent was required in five patients who were awaiting corrective surgery. In babies with pulmonary atresia or critical pulmonary stenosis, who also underwent additional balloon dilatation of the pulmonary valve, spontaneous closure of the stented arterial duct was well tolerated and when it occurred, the right ventricular size had increased and the circulation was no longer duct-dependent. In patients who required subsequent surgical corrective treatment, stenting of the duct allowed the definite corrective operation to be performed as the first surgical procedure. During the follow-up period, ranging between 2 months and 2 years, mean 8.7 months increased growth of the pulmonary arteries was seen in all the patients. No distortion of the branch pulmonary arteries was seen. CONCLUSION In patients with cyanotic congenital heart disease stenting of the arterial duct is an effective alternative to surgical aorto-pulmonary shunts.

Abstract
Tetralogy of Fallot with pulmonary atresia and major aortopulmonary collaterals is a complex lesion distinguished by marked heterogeneity of pulmonary blood supply. Over the past two decades, investigators have developed various approaches to the management of this anomaly generally based on the concept of staged unifocalization of pulmonary blood supply. Although such approaches may represent an improvement on the natural history of this lesion, they remain inadequate for a substantial portion of patients born with tetralogy of Fallot and major aortopulmonary collaterals. Since 1992, our approach has been to perform one-stage complete unifocalization through a midline approach in all but a few extremely complicated patients. We aim to repair these patients early in infancy, with an emphasis on native tissue-tissue reconstruction, in order to optimize prospects for survival with a good functional outcome in as many patients as possible. In this review, we present our philosophy and our experience with unifocalization and repair in 72 patients.

Abstract
The Richardson classification system for aortopulmonary septal defect (APSD) includes simple defects between the ascending aorta and pulmonary trunk (type I), defects extending distally to include the origin of the right main pulmonary artery (type II), and anomalous origin of the right main pulmonary artery from the ascending aorta with no other aortopulmonary communication (type III). These are rare lesions that must be repaired in early infancy to avoid development of pulmonary vascular disease. Few reports have focused on patients with complex, associated lesions who underwent repair in early infancy. Between 1972 and 1995, 24 patients with Richardson type I (n = 11), II (n = 7), or III (n = 6) defects underwent repair at ages ranging from 2 to 172 days (median 34). Twelve patients had complex, associated anomalies, including interrupted or hypoplastic arch (n = 9), tetralogy of Fallot with (n = 1) or without (n = 1) pulmonary atresia, and transposition of the great arteries (n = 1). The most recent 7 patients were diagnosed by echocardiography without cardiac catheterization. There were no early or late deaths among the 12 patients with simple APSD. Four patients with complex, associated lesions died in the early postoperative period and another died 4 months after surgery. All 6 surviving patients with interrupted arch have had recurrent obstruction at the arch repair site, although reintervention for this reason has been performed in only 2 patients. Altogether, 6 early survivors have required reintervention, and all survivors are in New York Heart Association class I at follow-up ranging from 2 to 25 years. Thus, long-term survival after repair of APSD in early infancy is excellent. Late sequelae are likely to be related either to associated lesions or to obstruction at the APSD repair site. Almost all cases of APSD in young infants can be diagnosed and evaluated by echocardiography without catheterization.

Abstract
Seventy-two patients with corrected transposition of the great arteries with ventricular septal defect and pulmonary obstruction were studied. Four deaths occurred in the neonatal period and two were lost to follow-up. The remaining 66 were divided into three groups: 1) Eight patients were not operated on because the lesions were well compensated; they are all alive and doing well eight years later. 2) Thirty-eight patients were treated with palliative surgery: one or more systemico-pulmonary shunts (33 cases), total cavo-pulmonary connection (1 case) and partial cavo-pulmonary connection complementary to a shunt (4 cases). There were 3 deaths and 17 patients were lost to follow-up. However, the 18 survivors are all well seven years later. 3) The other 20 patients underwent surgery for severe hypoxia, after previous shunt in 18 cases. A conventional surgical protocol was respected in 17 cases (closure of ventricular septal defect with pulmonary disobstruction by a direct pulmonary plasty or by ventriculo-pulmonary conduit). There were 4 deaths, 2 tricuspid valve replacements, 5 complete atrioventricular blocks requiring permanent pacing, 5 lost to follow-up and 8 good results after 4 years follow-up. In the last 3 cases, "anatomical" correction was attempted by tunnelling of the left ventricle to the aorta, conduit from the right ventricule to the pulmonary artery and intra-atrial Mustard procedure: these 3 children are doing well after 1 year though one of them required permanent pacing. Therefore, there is no place for elective surgery in this malformation: when necessary, the best option is to remain palliative as long as possible: when correction is required, an anatomical correction is the best procedure.

Abstract
BACKGROUND Children with pulmonary atresia and an intact ventricular septum show a heterogeneous spectrum of cardiac anomalies. A biventricular repair is attainable in some; a Fontan procedure or a one-and-a-half ventricle is the only possible repair for others. Children with right ventricle-to-coronary artery connections, with or without right ventricle-dependent coronary artery blood flow, are a high-risk group. METHODS Between May 1980 and December 1994, 22 children underwent a Fontan operation for the treatment of pulmonary atresia with an intact ventricular septum at The Hospital for Sick Children, Toronto. The mean age was 5.8 years (median, 4.9 years). All children had had at least one pre-Fontan palliative procedure; 19 had two, and 7 of these had three or more. Right ventricle-to-coronary artery connections were present in 15 children, including 5 with right ventricle-dependent coronary artery blood flow. Thromboexclusion of the right ventricle was done in 10 children, with 7 undergoing it before and 3 at the time of the Fontan procedure. RESULTS There were three early deaths (13.6%) and one late death. The actuarial survival at 10 years after the Fontan operation was 80%. Early postoperative complications occurred in 4 children. Follow-up was completed in all children at a mean of 4 years (range, 1 to 12.5 years) after the Fontan operation. Atrial arrhythmia occurred in 3 children, and permanent pacemakers were required in 4. CONCLUSIONS Results of the Fontan operation for the treatment of pulmonary atresia with an intact ventricular septum are satisfactory. Thromboexclusion of the right ventricle is indicated in the presence of right ventricle-to-coronary artery connections without right ventricle-dependent coronary artery blood flow. The right ventricle should not be decompressed or thromboexcluded in children with right ventricle-dependent coronary artery blood flow, and at the Fontan operation, saturated blood must enter the right ventricle.

Abstract
BACKGROUND The surgical approach to children with complex cardiovascular and pulmonary anomalies is still controversial. Staged operations through multiple incisions are often performed in this setting. OBJECTIVE The different applications and clinical advantages of a bilateral thoracosternotomy approach to complex cardiothoracic disease requiring surgical repair were reviewed retrospectively. METHODS Between January 1993 and June 1995, 33 patients, aged between 2 months and 17 years (mean 7.8 +/- 5.3) underwent surgical treatment of complex cardiovascular or pulmonary disease using a clamshell approach. Twenty-one patients (64%) had undergone 1-5 previous surgical procedures (mean 2.5 +/- 1.0/patient). The technique involved supine position placement, submammary incision, access to the pleural space bilaterally through the fourth intercostal space and transverse division of the sternal body. RESULTS Four groups of patients were operated on via this approach: (1) patients undergoing lobar, lung or heart-lung transplantation (40%); (2) patients undergoing repair of tetralogy of Fallot/pulmonary atresia (36%); (3) patients with previously corrected miscellaneous procedures (12%), including completion of Fontan, one-stage repair of left main bronchial stenosis and atrial septal defect, one-stage repair of partial anomalous pulmonary venous connection and aortic coarctation, and repair of congenital pulmonary venous stenosis. There were two early (< 30 days) deaths, giving a perioperative mortality of 6% for the entire series. Complications included postoperative hemorrhage in 4 patients (12%), prolonged ventilation time due to mechanical failure in 4 (12%). There were no wound infections. Analysis of complications by group showed the lung transplant group to be more affected (18% of patients experienced complications). Except for 2 infants undergoing complete unifocalization and presently awaiting completion of repair of tetralogy of Fallot/pulmonary atresia, in the remaining 31 (94%) a definitive surgical treatment could be performed in one-stage. CONCLUSIONS The bilateral thoracosternotomy allows optimal exposure of all intrathoracic anatomic structures making one-stage surgical repair possible in a variety of complex cardiovascular and pulmonary anomalies. Early mortality and technique-related morbidity do not differ from those reported with the conventional approaches to the different disease conditions. A wider application of the clamshell approach for the management of complex intrathoracic pathology in infants and children is advocated.

Abstract
Since September 1991, 14 consecutive patients with tetralogy of Fallot, pulmonary atresia, and diminutive pulmonary arteries have undergone staged repair. All patients had multiple aortopulmonary collateral arteries and the ductus arteriosus was absent in 11. Mean sizes of the right and left pulmonary arteries were 2.2 +/- 0.7 mm and 1.9 +/- 0.8 mm, respectively (range 0.5 to 3.0 mm). Eight patients (57%) have subsequently received complete repair. Age at initial procedure (shunt, right ventricle-pulmonary artery conduit, or direct aorta-pulmonary artery anastomosis) in this group was 5.3 +/- 6.8 months. The number of operative procedures to achieve complete repair was 2.9 +/- 0.8 per patient (range 2 to 4). Intraoperative postrepair peak right ventricle-left ventricle pressure ratio was 0.57 +/- 0.17. Six of 8 patients (75%) required additional interventional procedures (mean 1.5 +/- 1.2 per patient) for angioplasty of peripheral pulmonary artery stenoses, coil embolization of aortopulmonary collateral arteries, or intra-operative insertion of intravascular pulmonary artery stents. Mean follow-up from complete repair was 8.7 +/- 8.3 months (range 0.5 to 23.8 months) and is complete. There was one in-hospital death at 45 days, and one late cardiac death at 20.3 months. Six patients had initial palliative operations (unifocalization, right ventricle-pulmonary artery conduit, direct aorta-pulmonary artery anastomosis, or transannular outflow patch) but have not undergone complete repair. Age at initial procedure in this group was 27.9 +/- 56.9 months (range 0.27 to 155 months), and mean follow-up from initial procedure was 10.9 +/- 11.2 months (range 0 to 31.4 months). The operative mortality rate was 33% (2 of 6 patients). There was one late noncardiac death at 5.3 months. Three patients are awaiting further intervention or repair. This experience suggests that complete repair is feasible even in patients with extremely diminutive pulmonary arteries (< or = 3.0 mm). Pulmonary artery growth is facilitated by early (3 to 6 month) establishment of central pulmonary artery flow by right ventricle-pulmonary artery conduit (pulmonary arteries > 1.5 mm) or by direct ascending aorta-pulmonary artery anastomosis (pulmonary arteries < 1.5 mm). Subsequent interventional catheterization and operative procedures as required for pulmonary artery stenoses and coil embolization of collateral arteries allow continued recruitment of central pulmonary arteries and may obviate or minimize the need for unifocalization procedures.

Abstract
Mortality is high for children with pulmonary atresia, intact ventricular septum, and important connections between the right ventricle and the coronary arteries because of myocardial ischemia: in systole, suprasystemic right ventricular pressure delivers deoxygenated blood to the coronary artery (or arteries) and in diastole, the right ventricle provides a lower resistance alternative to coronary perfusion of the myocardium. Tricuspid valve closure was performed in 10 such children. None had stenosis of native coronary arteries. A trial of tricuspid valve closure (by balloon) was performed in the cardiac catheterization laboratory in 5 of 10 patients. Seven of 10 children survived surgical closure of the tricuspid valve plus concurrent procedures; none had heart block. Two of the 3 nonsurvivors were probably in inoperable condition due to preoperative myocardial ischemia. Before operation, 4 patients had ischemic changes on electrocardiograms; these changes were abolished after operation. Three of 10 patients have had a Fontan operation with 2 survivors. We conclude that children with pulmonary atresia, intact ventricular septum, important connections between the right ventricle and the coronary arteries, and normal native coronary arteries should have surgical closure of the tricuspid valve within the first year of life and treated thereafter as patients with "tricuspid atresia."
