Abstract
BACKGROUND Identification of risk factors for biventricular (BiV) repair in children with hypoplastic left ventricles (HLV) has been challenging. We sought to identify preoperative cardiovascular magnetic resonance (CMR) predictors of outcome in patients with HLVs who underwent BiV repair, with a focus on the mitral valve (MV). METHODS Single-center retrospective analysis of preoperative CMRs on patients with HLV (≤50 mL/m2) and no endocardial fibroelastosis who underwent BiV repair from 2005-2022. CMR measurements included MV orifice area in diastole. The primary composite outcome included time to death, transplant, BiV takedown, heart failure admission, left atrial decompression, or unexpected reoperation; and the secondary outcome included more than or equal to moderate mitral stenosis and/or regurgitation. RESULTS Median follow-up was 0.7 (interquartile range 0.1, 2.2) years. Of 122 patients [59 atrioventricular canal (AVC) and 63 non-AVC] age 3 ± 2.8 years at the time of BiV repair, freedom from the primary outcome at 2 years was 53% for AVC and 69% for non-AVC (log rank p = 0.12), and freedom from the secondary outcome at 2 years was 49% for AVC and 79% for non-AVC (log rank p < 0.01). Independent predictors of primary outcome for AVC patients included MV orifice area z-score <-2 and transitional AVC; for non-AVC patients, predictors included MV orifice area z-score <-2, abnormal MV anatomy, and conal-septal ventricular septal defect. Independent predictors of secondary outcome for AVC patients included older age at surgery, transitional AVC, and transposition of the great arteries. CONCLUSION In children with HLV, low MV orifice area and pre-existing MV pathology are risk factors for adverse outcome after BiV repair.

Abstract
OBJECTIVES A double orifice of the left atrioventricular valve (LAVV) associated with atrioventricular septal defects (AVSD) can significantly complicate surgical repair. This study reports our experience of AVSD repair over 3 decades, with special attention to the zone of apposition (ZoA) of the main orifice, and presents a technique of hemivalve pericardial extension in specific situations. METHODS We performed a retrospective study from 1987 to 2016 on 1067 patients with AVSD of whom 43 (4%) had a double orifice, plus 2 additional patients who required LAVV pericardial enlargement. Median age at repair was 1.3 years. Mean follow-up was 8.2 years (1 month-32 years). RESULTS Associated abnormalities of the LAVV subvalvular apparatus were found in 7 patients (5 parachute LAVV and 2 absence of LAVV subvalvular apparatus). ZoA was noted in 4 patients (9%): partially closed in 15 (35%) and completely closed in 24 (56%). Four patients required, either at first repair or secondarily, a hemivalve enlargement using a pericardial patch without closure of the ZoA. The early mortality rate was 7% (n = 3), all before 2000. Two patients had unbalanced ventricles and the third had a single papillary muscle. There were no late deaths. Six patients (14%) required 7 reoperations (3 early and 4 late reoperations) for LAVV regurgitation and/or dysfunction, of whom 4 (9%) required mechanical LAVV replacement (all before 2000). Freedom from late LAVV reoperation was 97% at 1 year, 94% at 5 years and 87% at 10, 20 and 30 years. Unbalanced ventricles (P = 0.045), subvalvular abnormalities (P = 0.0037) and grade >2 LAVV postoperative regurgitation (P = 0.017) were identified as risk factors for LAVV reoperations. Freedom from LAVV mechanical valve replacement was 95% at 1 year, 90% at 5 years and 85% at 10, 20 and 30 years. An anomalous LAVV subvalvular apparatus was identified as a risk factor for mechanical valve replacement (P = 0.010). None of the patients who underwent LAVV pericardial extension had significant LAVV regurgitation at the last follow-up examination. CONCLUSIONS Repair of AVSD and double orifice can be tricky. Preoperative LAVV regurgitation was not identified as an independent predictor of surgical outcome. LAVV hemivalve extension appears to be a useful and effective alternate surgical strategy when the ZoA cannot be closed.

Abstract
A 4-year-old, 5.9-kg female Japanese Spitz presented with syncope and exercise intolerance. Echocardiography revealed an ostium primum atrial septal defect (ASD), a cleft mitral valve,
mitral valve regurgitation (MR), and tricuspid regurgitation (TR) (velocity: 3.6 m/sec, pressure gradient: 52 mmHg), leading to a diagnosis of partial atrioventricular septal defect (AVSD)
with moderate pulmonary hypertension (PH). Open-heart surgery using cardiopulmonary bypass was performed through right atriotomy. The cleft of the mitral valve was sutured with polypropylene
and the AVSD was closed using an autologous pericardial patch fixed with glutaraldehyde. No postoperative pulmonary hypertensive crisis occurred. Shunting flow through the ASD, TR and PH had
completely disappeared 2 months postoperatively; however, moderate MR persisted. The dog is still alive 5 years postoperatively without clinical signs.

Abstract
While the epidemiology of adult heart failure has been extensively researched, this systematic review addresses the less well characterized incidence and prevalence of pediatric HF. The search strategy used Cochrane methodology and identified 83 unique studies for inclusion. Studies were categorized according to whether the HF diagnosis was reported as primary (n = 10); associated with other cardiovascular diseases (CVDs) (n = 49); or associated with non-CVDs (n = 24). A narrative synthesis of the evidence is presented. For primary HF, the incidence ranged from 0.87/100,000 (UK and Ireland) to 7.4/100,000 (Taiwan). A prevalence of 83.3/100,000 was reported in one large population-based study from Spain. HF etiology varied across regions with lower respiratory tract infections and severe anemia predominating in lower income countries, and cardiomyopathies and congenital heart disease major causes in higher income countries. Key findings for the other categories included a prevalence of HF associated with cardiomyopathies ranging from 36.1% (Japan) to 79% (US); associated with congenital heart disease from 8% (Norway) to 82.2% (Nigeria); associated with rheumatic heart diseases from 1.5% (Turkey) to 74% (Zimbabwe); associated with renal disorders from 3.8% (India) to 24.1% (Nigeria); and associated with HIV from 1% (US) to 29.3% (Brazil). To our knowledge, this is the first systematic review of the topic and strengthens current knowledge of pediatric HF epidemiology. Although a large body of research was identified, heterogeneity in study design and diagnostic criteria limited the ability to compare regional data. Standardized definitions of pediatric HF are required to facilitate cross-regional comparisons of epidemiological data.

Abstract
BACKGROUND Repair of partial or transitional atrioventricular septal defects (P/TAVSDs) has excellent outcomes; however, late reinterventions remain a concern. Technical performance score (TPS) measures residua after repair and has been associated with early/mid-term outcomes after congenital cardiac operation. Our study investigates TPS as a predictor of outcomes after P/TAVSD repair. METHODS This was a single-center retrospective review of P/TAVSD repair from July 2000 to November 2015. Intraoperative and discharge TPS were assigned based on echocardiographic criteria: class 1, no residua; class 2, minor residua; and class 3, major residua or reintervention for major residua. Intensive care unit (ICU) hospital length of stay and reintervention after discharge were analyzed with Cox regression. RESULTS In our cohort, 124 partial (68%) and 59 transitional (32%) AVSDs underwent repair. Median age was 1.5 years (interquartile range [IQR]: 0.6 to 3.8 years), median weight was 9.7 kg (IQR: 6.6 to 14.1 kg), and 96 (52%) were female. Twenty patients (11%) required reintervention after discharge. On multivariable modeling, patients with TPS class 3 spent more days in the ICU (hazard ratio [HR] 0.33, 95% confidence interval [CI]: 0.19 to 0.58, p < 0.001) and hospital (HR 0.33, 95% CI: 0.19 to 0.57, p < 0.001) and had shorter time to reintervention after discharge (HR 8.76, 95% CI: 1.03 to 74.7, p = 0.047). CONCLUSIONS Major residua, that is TPS class 3, were a predictor of in-hospital outcomes and unplanned reinterventions after discharge, with left atrioventricular valve regurgitation being the strongest predictor. Use of TPS as a tool for residual lesions may identify patients predisposed to prolonged ICU hospital stay and reinterventions after discharge, providing feedback on areas in need of improvement in technique and identification of patients who warrant closer follow-up.

Abstract
OBJECTIVE Partial atrioventricular septal defect (pAVSD) is usually repaired between 2 and 4 years of age with excellent results. Repair during infancy has been associated with poorer outcomes. However, most infants in reported series had heart failure or significant left atrioventricular valve (LAVV) regurgitation. The impact of surgery during infancy on outcomes remains unclear. METHODS All children at three institutions who underwent repair of pAVSD from 1975 to 2015 were included. Infants (aged <1 year) were compared with older children in a propensity score matched analysis. Variables used to generate propensity scores were: failure to thrive, congestive heart failure, preoperative LAVV regurgitation, associated congenital heart disease, sex and the presence of trisomy 21. RESULTS pAVSD repair was performed on 430 children, 17.4% (75/430) were infants. Infants (mean age 0.5±0.3 years) had higher rates of LAVV regurgitation, heart failure and additional cardiac malformations than older children (mean age 4.7±3.5 years). At 30 years, survival for infants was 82.1% (95% CI 70.1% to 89.6%) compared with 95.7% (95% CI 91.3% to 97.9%) in older children (P<0.001).Propensity score matching yielded 52 well-matched pairs. Survival at 30 years was 87.9% (95% CI 75.0% to 94.4%) for infants compared with 98.1% (95% CI 87.1% to 99.7%) for older children (P=0.04). There was no significant difference in freedom from reoperation between the groups. CONCLUSIONS Despite matching for risk factors, survival after repair of pAVSD during infancy is lower than that when repair is performed in older children, with no difference in reoperation rates. This suggests that elective repair of pAVSD should be deferred until after infancy.

Abstract
Long-term survival rate of patients operated for partial atrioventricular (AV) canal is lower than that of the general population, and late complications are relatively significant: between 10 and 30% of operated patients present with left AV valve regurgitation, and up to 25% have to be reoperated for valve repair or replacement, left ventricular outflow tract obstruction or residual atrial septal defect. Because the left AV valve regurgitation is the most common complication following surgery, technical details in the surgical management of the mitral valve are the most important aspects of this procedure; for example, the decision to close the cleft and to perform an annuloplasty. The presence of mitral valve anomalies in 7-28% of the cases complicates further the surgical management of these valves. This article will describe in detail the operative technique of partial AV canal repair, and review the relevant literature.

Abstract
OBJECTIVES Postoperative left atrioventricular valve (LAVV) dysfunction is known to be the principal risk factor influencing outcome after repair of all types of atrioventricular septal defect (AVSD). The purpose of the present study was to identify the risk factors for reoperation and to assess the outcomes after reoperation for LAVV dysfunction. METHODS Records of 412 patients who underwent anatomical repair for different types of AVSD from January 2000 to July 2012 were reviewed. The study group (n = 60) included 13 additional patients for whom repair ± LAVV reoperation was performed in a primary institution. Outcomes, independent risk factors, reoperation and death were analysed. RESULTS There were 7 early, (1.7%) and 1 late death. Forty-seven (11.4%) required 64 reoperations for LAVV dysfunction. The median delay for the first LAVV reoperation was 3.5 months (range: 5 days to 10.0 years). Unbalanced ventricles with small left ventricle [odds ratio (OR) = 4.06, 95% confidence interval (CI): 1.58-10.44, P = 0.004], double-orifice LAVV (OR = 5.04, 95% CI: 1.39-18.27, P = 0.014), prior palliative surgery (OR = 3.5, 95% CI: 1.14-10.8, P = 0.029) and discharge echocardiography documenting LAVV regurgitation grade >2 (OR = 21.96, 95% CI: 8.91-54.09, P < 0.001) were found to be independent risk factors for LAVV reoperation. Twelve-year survival and freedom from LAVV reoperation rates were, respectively, 96.1% (95% CI: 94.1-98.1) and 85.8% (95% CI: 81.3-90.3). Survival was significantly worse in patients who underwent LAVV reoperation (P < 0.001) and in those who underwent valve replacement vs valve repair (P = 0.020). CONCLUSION After AVSD repair, LAVV dysfunction appears to be the principal factor that influences outcome. It can usually be managed by repair. Need for multiple reoperations is not uncommon. Long-term outcome in patients with repaired LAVV is favourable.

Abstract
Advances in cardiology and cardiac surgery allow a large proportion of patients with congenital heart defects to survive into adulthood. These patients frequently develop complications characteristic of the defect or its treatment. Consequently, adult cardiologists participating in the care of these patients need a working knowledge of the more common defects. Occasionally, patients with congenital heart defects such as atrial septal defect, Ebstein anomaly or physiologically corrected transposition of the great arteries present for the first time in adulthood. More often patients previously treated in pediatric cardiology centers have transitioned to adult congenital heart disease centers for ongoing care. Some of the more important defects in this category are tetralogy of Fallot, transposition of the great arteries, functionally single ventricle defects, and coarctation. Through this field guide, we provide an overview of the anatomy of selected defects commonly seen in an adult congenital practice using pathology specimens and clinical imaging studies. In addition, we describe the physiology, clinical presentation to the adult cardiologist, possible complications, treatment options, and outcomes.

Abstract
Atrioventricular septal defect with common atrioventricular junction is a relatively common congenital cardiac malformation. It sometimes presents challenging surgical problems, especially when seen in combination with tetralogy of Fallot. We describe herein our current concepts regarding surgical repair of atrioventricular septal defect with and without tetralogy, discussing indications for surgery, timing, technical aspects, and outcomes.

Abstract
The most common cause of reoperation following repair of atrioventricular septal defect (AVSD) is left atrioventricular valve regurgitation. However, reoperation for subaortic obstruction is required in some, especially after initial repair of partial AVSD. Etiology of reoperation and late outcome were evaluated. Between 1962 and 2007, 146 patients (59 male) underwent reoperation at the authors' institution after prior repair of partial (n = 96) and complete (n = 50) AVSD. Median age at reoperation after repair of partial AVSD was 26 years (range, 10 months to 71 years) and 4.5 years (range, 53 days to 38 years) after repair of complete AVSD. The 3 most common indications for reoperation included left atrioventricular (AV) valve regurgitation in 105 patients, subaortic stenosis in 29, and right AV valve regurgitation in 21. The most common procedures performed included left AV valve repair in 59 (40%) patients, left AV valve replacement in 56 (38%), subaortic fibrous resection/myectomy in 24 (16%), and right AV valve surgery in 19 (13%). Freedom from subsequent reoperation at 10 years was 48% after initial repair of complete AVSD and 84% after initial repair of partial AVSD. During late follow-up, 10-year actuarial survival was 91% and 77% after initial repair of complete and partial AVSD, respectively. The most common indication for reoperation after initial repair of partial or complete AVSD is left AV valve pathology; left ventricular outflow tract obstruction was more common in partial AVSD. Although freedom from subsequent reoperations is higher after initial repair of partial AVSD, these patients have reduced long-term survival when compared with complete AVSD.

Abstract
OBJECTIVE To assess the anatomical features and the associations of partial atrioventricular septal defect (pAVSD) in the fetus. METHODS This was a retrospective multicenter study of 30 cases of confirmed pAVSD seen since 1996 at two referral centers. The following variables were available for analysis in all cases: indications for fetal echocardiography, diagnostic features, associated cardiac, extracardiac and chromosomal anomalies and fetoneonatal outcome. At fetal echocardiography, the echocardiographic features deemed indicative of pAVSD were: 1) ostium primum atrial septal defect and 2) loss of the normal offset appearance of the atrioventricular valves. RESULTS Eighteen of the 30 (60%) cases were diagnosed before 24 weeks of gestation and 12 were diagnosed later. Suspicion of congenital heart disease and known aneuploidy (trisomy 21) accounted for 60% of the referral indications. The two anatomical landmarks deemed indicative of pAVSD were detected in all cases at echocardiography. Twelve cases were isolated (one with increased nuchal transluceny at the 12-week scan, one with polyhydramnios, one with fetal growth restriction) including four that were detected on routine ultrasound examination by the authors. Additional cardiac anomalies were present in five (17%) cases, four of which involved aortic coarctation. There were associated chromosomal anomalies in 13 (43%); however, excluding the six cases referred because of known Down syndrome, the adjusted association rate with aneuploidy was 29.2% (7/24). Extracardiac anomalies, including non-chromosomal syndromes, were present in 10 cases (33.3%). Regarding fetoneonatal outcome, there were 13 terminations of pregnancy, one early neonatal death and 16 survivors, including four with mild to severe neurodevelopmental delay due to associated syndromic conditions. CONCLUSIONS We describe the key echocardiographic features of pAVSD in the fetus. In addition, we have confirmed that the association with trisomy 21 holds also for pAVSD, though to a lesser extent, with a 12.5% association rate in this series. In the fetus, pAVSD seems to be associated with a high rate of chromosomal/non-chromosomal syndromic conditions, including skeletal dysplasias. Inutero, aortic coarctation represents the most frequently associated cardiac lesion (13.3%).

Abstract
Closure of a mitral valve (MV) cleft, small left-sided cardiac structures, and ventricular imbalance all may contribute to mitral stenosis (MS) after repair of atrioventricular canal (AVC) defects. MV replacement is the traditional therapy but carries high risk in young children. The utility of balloon mitral valvuloplasty (BMV) in postoperative MS is not established and may offer alternative therapy or palliation. Since 1996, 10 patients with repaired AVC defects have undergone BMV at a median age of 2.5 years (range 8 months to 14 years), a median of 2 years after AVC repair. At catheterization, the median value of mean MS gradients was 16 mm Hg (range 12 to 22) and was reduced by 34% after BMV. Before BMV, there was mild mitral regurgitation in 9 of 10 patients, which increased to severe in 1 patient. All patients were alive at follow-up (median 5.4 years). Repeat BMV was performed in 4 patients, 10 weeks to 18 months after initial BMV. One patient underwent surgical valvuloplasty; 3 underwent MV replacement 2, 3, and 28 months after BMV. In the 6 patients (60%) with a native MV at most recent follow-up (median 3.2 years), the mean Doppler MS gradient was 9 mm Hg, the median weight had doubled, and weight percentile had increased significantly. In conclusion, BMV provides relief of MS in most patients with repaired AVC defects; marked increases in mitral regurgitation are uncommon. Because BMV can incompletely relieve obstruction and increase mitral regurgitation, it will not be definitive in most patients but will usually delay MV replacement to accommodate a larger prosthesis.

Abstract
Atrial septal defects (ASDs) are typically asymptomatic in infancy and early childhood, and elective defect closure is usually performed at ages of 4 to 6 years. Severe pulmonary hypertension (PH) complicating an ASD is seen in adulthood and has only occasionally been reported in small children. A retrospective study was undertaken to evaluate the incidence of severe PH complicating an isolated ASD and requiring early surgical correction. During a 10-year period (1996 to 2006), 355 pediatric patients underwent treatment for isolated ASDs either surgically or by catheter intervention at 2 tertiary referral centers. Two hundred ninety-seven patients had secundum ASDs, and 58 had primum ASDs with mild to moderate mitral regurgitation. Eight infants were found with isolated ASDs (6 with secundum ASDs and 2 with primum ASDs) associated with significant PH, accounting for 2.2% of all patients with ASDs at the centers. These 8 infants had invasively measured pulmonary artery pressures of 50% to 100% of systemic pressure. They were operated in the first year of life and had complicated postoperative courses requiring specific treatment for PH for up to 16 weeks postoperatively. The ultimate outcomes in all 8 infants were good, with persistent normalization of pulmonary pressures during midterm follow-up of up to 60 months (median 28). All other patients with ASDs had normal pulmonary pressures, and the mean age at defect closure was significantly older, at 6.2 years for secundum ASDs and 3.2 years for primum ASDs. In conclusion, ASDs were rarely associated with significant PH in infancy but then required early surgery and were associated with excellent midterm outcomes in these patients.

Abstract
BACKGROUND This investigation was designed to determine long-term survival, reoperation rates, and functional status after surgical repair of partial atrioventricular septal defect (PAVSD). METHODS This population-based cohort study with cumulative, prospective follow-up by questionnaire and medical record review included all patients aged younger than 19 years old in the state of Oregon who underwent surgical repair of a PAVSD from 1958 to 2000. The incidence of early death, late death, and reoperation for left atrioventricular valve pathology were determined. Patient-reported health status as measured by the Medical Outcomes Study Short Form 12 (SF-12) was obtained for patients without Down syndrome when they were aged older than 15 years. RESULTS Repair of PAVSD was done in 133 patients. Median follow-up was 8.7 years for a total of 1541 person-years. Mean age at the initial operation was 5.2 +/- 5.1 years (median, 3.4 years). Mean weight was 19.2 +/- 16.0 kg (median, 13.2 kg). Survival was 95% at 30 days, 87% at 10 years, and 78% at 30 years. Reoperation for left atrioventricular valve pathology was done 15 patients (11.3%). Lower weight, absence of Down syndrome, and lack of mitral valve cleft repair were significantly associated with undergoing reoperation. Patient-reported health status was obtained in 35 patients. For this group, the mean SF-12 summary scores for the physical component (52.8 +/- 9.0) and the mean mental component (50.3 +/- 11.0) were not significantly different from age-adjusted norms. CONCLUSIONS The survival rate for this simple cardiac defect is lower than the general population. In addition, the reoperation rate is significant. Despite this, in general, patients without Down syndrome can expect normal functional health status.

Abstract
Partial atrioventricular (AV) canal represents approximately 25% of all AV septal defects. While often grouped with secundum ASD from the perspective of cardiopulmonary physiology, clinical presentation, and timing of surgical correction, their optimal management truly requires an understanding of their anatomic similarities to other forms of common AVC defects. By most measures, outcomes for surgical management of partial AV canal has improved over the last four decades, though some aspects of these defects continue to pose important challenges. Current experience has witnessed the reduction in early mortality and only rare complete heart block. Left AV valve dysfunction remains the most common indication for reoperation (10%) with LVOT stenosis the next most common reason (10% to 15% incidence, 5% to 10% reoperation rate). It is important to understand in this population that postoperative left AV valve problems and LVOT stenosis may be intimately linked, both from an etiologic standpoint, and with respect to their management.

Abstract
A single surgeon experience using a modified single patch technique for the repair of 128 patients with complete atrioventricular canal is presented. Thirty-day mortality was 1.6%. Follow-up of these patients has shown no incidence of significant residual ventricular septal defect, a 2.3% incidence of reoperation on the mitral valve, and no instances of left ventricular outlet obstruction requiring resection in the follow-up period. Comparisons are drawn between these results and the author's own experience with repair of complete atrioventricular canal using a two-patch technique (46 cases) and repair of partial atrioventricular canal (126 cases) to shed light on late valve function and left ventricular outlet obstruction in all groups.

Abstract
OBJECTIVES The purpose of this study was to determine whether 3-dimensional echocardiography (3DE) provides additional information regarding the mechanisms and sites of left atrioventricular valve regurgitation in atrioventricular septal defect compared with transesophageal 2-dimensional echocardiography (2DE). METHODS Eleven patients with a median age of 5.4 years (2.9-11.6 years) and a median weight of 16.8 kg (13.7-38.3 kg) with an atrioventricular septal defect underwent simultaneous transesophageal 2DE and 3DE before operation. RESULTS The 2DE-3DE agreement for the assessment of the superior and mural leaflet size was 72.7%. The 2DE-3DE agreement for coaptation failure, a residual or primary cleft, and commissural abnormalities as a mechanism of regurgitation were 72.7%, 63.6%, and 36.4%, respectively. For jet sites the 2DE-3DE agreement was 63.6% for a commissural and central location. CONCLUSION Three-dimensional echocardiography provides new and superior data regarding the mechanisms and sites of left atrioventricular valve regurgitation in atrioventricular septal defect.

Abstract
OBJECTIVE Left atrioventricular valve pericardial patch may prevent valve replacement. We assessed patch annular dynamics compared with conventional repair and normal annuli. METHODS Transesophageal 3-dimensional echocardiography was acquired preoperatively and postoperatively in atrioventricular septal defects (n = 10, 5 patch, 5 conventional repair). Real-time 3-dimensional annular motion at midterm was compared with that of healthy children (n = 10). Parameters were: annular area, perimeter, segmental diameter, bending angle, stenosis, and regurgitation. RESULTS Regurgitant jet area ratio decreased in both patient groups. Conventional repair reduced annular area (P = .02). Patch repair showed an annular area larger than normal (P = .01). Control subjects had increased systolic area whereas operative groups showed a reduction. Patch repair had segmental diameters similar to normal whereas conventional repair was inhomogeneous. Annular bending angle was maintained after operation. CONCLUSION Patch repair in pediatrics shows durability without shrinkage or expansion. Improved stenosis and regurgitation does not change by midterm. Operation causes increased annular stiffness and diminished compliance. Neither technique establishes normal annular eccentricity.

Abstract
Patients with partial atrioventricular canal defect (PAVC) who present with congestive heart failure within the first year of life are usually found to have associated left-sided obstructive lesions. We present a case of a child with PAVC who subsequently developed progressive pulmonary venous stenosis as a manifestation of her disease.

Abstract
BACKGROUND Excellent surgical results have been reported for repair of incomplete atrioventricular septal defect; however, left atrioventricular valve regurgitation (ltAVVR) is a major cause of late morbidity. We reviewed our entire experience with incomplete atrioventricular septal defect in order to investigate long-term results of ltAVVR after repair and determine the factors influencing the progression of ltAVVR in late follow-up. METHODS Between 1983 and 2002, 61 patients underwent surgical repair of incomplete atrioventricular septal defect, including 7 patients with intermediate forms. The age of operation ranged from 1 month to 62 years old (median 5.3 years old). Thirteen patients were less than 2 years old, including 7 infants, while there were 15 adult patients. All patients underwent patch closure of the ostium primum defect. Before 1995, the cleft was left open in 7 patients and partial closure of the cleft was done in 41 patients, whereas complete closure of the cleft was performed in 9 patients since 1996. Preoperative and postoperative ltAVVR at hospital discharge and late follow-up were graded 0-IV by echographic evaluation. RESULTS There was 1 early death and 4 late deaths with a 91% 10-year actuarial survival rate. Preoperative ltAVVR grade was I in 25 patients, II in 31 patients, III in 4 patients, and IV in 1 patient. Postoperatively, ltAVVR deteriorated in 3 patients. Left AVVR decreased in 21 patients, whereas in 37 patients it remained the same at hospital discharge. Consequently, ltAVVR remained grade II in 18 patients, grade III in 2, and there was no patient with grade IV. During the long-term follow-up, 24 patients were noted to have increased ltAVVR, including grade III in 8 patients and grade IV in 4. Reoperations for ltAVVR were required in 5 patients (8.3% of hospital survivors); valve replacement in 3 patients and valve repair in 2. Actuarial freedom from reoperation for ltAVVR was 91% at 10 years, whereas actuarial freedom from postoperative ltAVVR grade III or more was 89% at 5 years and 78% at 10 years. Multivariate analysis indicated that postoperative ltAVVR grade II or more at hospital discharge (p = 0.0032, odds ratio = 7.41, 95%CI: 1.95-28.10) was the only independent variable related to late ltAVVR, whereas age at operation, preoperative grade of ltAVVR, and the method of cleft repair were not significant risk factors. CONCLUSIONS Left AVVR is still a significant risk in long-term follow-up. Because the postoperative grade of ltAVVR is the only independent risk factor for late ltAVVR, more efforts should be focused on left atrioventricular valve repair so as to minimize residual regurgitation, even mild regurgitation.

Abstract
PURPOSE To assess the reliability of ventricular septal position in predicting elevated right ventricular pressure (RVP) in patients with ostium primum atrial septal defects (ASD 1). METHODS Echocardiograms of 4 groups were retrospectively analyzed: Patients with ASD 1 and low RVP, patients with ASD 1 and high RVP, and 2 age-matched control groups: one with isolated ostium secundum atrial septal defects (ASD 2), and 1 with normal cardiac findings. End-systolic left ventricular sectional diameters along the midmitral diameter (D1) and a diameter orthogonal to it (D2) were measured off-line by a blinded observer. The ratio D2/D1, the eccentricity index (EI), was calculated; a higher index represents greater septal flattening. RESULTS The mean EI in the ASD 1 with low RVP group was significantly higher than both the group with ASD 2 and the healthy control group. The mean EI of the ASD 1 group with high RVP was significantly higher than the mean EI of the ASD 1 group with low RVP, although there was a poor correlation between EI and RVP in this group, r = 0.54. CONCLUSION The ventricular septum is flatter in the ASD 1 patients with low RVP than in an age-matched control group with ASD 2 and compared with an age-matched control group of healthy subjects, giving a false impression of elevated RVP in the ASD 1 group. Although the mean EI is significantly higher in the ASD 1 group with high RVP than in the group with low RVP, there is a poor correlation between EI and RVP, which limits the reliability of this index.

Abstract
OBJECTIVES Some features of the left atrioventricular valve (large mural leaflet, dystrophic tissue) represent a challenge for repair of atrioventricular septal defects without postoperative regurgitation. A retrospective study was conducted to evaluate the results of surgically creating a double-orifice left atrioventricular valve in such circumstances. Clinical results were analyzed according to valvular and subvalvular left atrioventricular valve measurements in pathologic specimens with atrioventricular septal defects. METHODS Among 157 patients operated on for atrioventricular septal defect since October 1989, 10 patients underwent primary repair (n = 8) or reoperation (n = 2) by this procedure. Median age at repair was 3.3 years (0.1-33 years). Anatomic types were complete (n = 3), intermediate (n = 5), and partial (n = 2). Preoperative moderate to severe left atrioventricular valve regurgitation was present in 6 patients. After the repair (two-patch technique in complete atrioventricular septal defect, cleft closed in each case), these 10 patients were found to have moderate to severe residual regurgitation not amenable to repair by annuloplasty. The top edge of the mural leaflet was anchored to the facing free edge of the cleft. RESULTS No hospital death or morbidity was observed. Left atrioventricular valve regurgitation was absent or trivial (8 patients) and mild (2 patients). Color-coded echocardiography did not show significant left atrioventricular valve stenosis. The mean diastolic pressure gradient across the left atrioventricular valve was 3.2 +/- 1.1 mm Hg (1.4-4.5 mm Hg). At a median follow-up of 72 months (6-91 months), there was 1 late death, unrelated to left atrioventricular valve malfunction, due to pulmonary vascular obstructive disease. Left atrioventricular valve regurgitation did not increase over time, except in 1 patient in whom regurgitation recently progressed from mild to moderate. At rest, the mean diastolic pressure gradient across the left atrioventricular valve was 3.8 +/- 2.9 mm Hg (1.5-11.2 mm Hg). One child had an early moderate stenosis without pulmonary hypertension. Studies on pathologic specimens (n = 34) indicated that long chordal lengths and large mural leaflet size are essential independent anatomic features to assess its feasibility. CONCLUSIONS Surgical creation of a double-orifice left atrioventricular valve is an effective additional procedure for repair of atypical cases of atrioventricular septal defect. The operation may decrease the need for reoperation or left atrioventricular valve replacement.

Abstract
OBJECTIVE Left atrioventricular valve regurgitation (LAVVR) is the most frequent indication for reoperation following atrioventricular septal defect (AVSD) repair. We estimate from our experience that within 10 years of initial repair, 14% of patients undergoing repair of atrioventricular septal defect (AVSD) require reoperation for this complication. We have developed a novel leaflet augmentation technique for LAVVR which may avoid failure of conventional repair and/or the need for valve replacement. METHOD The novel technique consists of insertion of a glutaraldehyde-treated autologous pericardial patch to augment the bridging leaflets of the atrioventricular valve. We describe the outcome of eight patients in whom this technique was used and compared them to 68 other patients with AVSD undergoing reoperation for LAVVR by either conventional repair (n=54) or valve replacement (n=14). RESULTS There were no early deaths or major complications following patch repair. The mean follow-up is 2.3 years (range 1-8.5 years) during which there were no late deaths. Two patients underwent reintervention at 3.5 and 5 years after patch repair for LAVVR and were successfully rerepaired. Mild residual LAVVR was seen at last echocardiography in six patients and mild to moderate in two. These results compare favorably with the 68 patients who underwent conventional surgery. The 3-year freedom from reoperation was 86% for both repair groups. Dysplastic valve tissue appears to be a major risk factor for failure of conventional repair or for valve replacement. Failure of conventional valve repair led to valve replacement in six of seven patients. CONCLUSIONS For patients with late LAVVR after AVSD repair, pericardial leaflet augmentation is durable and may avoid failure of conventional repair or valve replacement in patients with dysplastic valves.

Abstract
BACKGROUND Narrowing of the left ventricular outflow tract has been associated with partial atrioventricular septal defect (PAVSD) in about 3% of patients. Because of the predisposing anatomy, hemodynamically significant obstruction in the subaortic area may appear after repair of ostium primum atrial septal defects. METHODS From 1984 to 1998, 40 patients underwent surgical correction of PAVSD by patch closure. The mean age at the initial repair was 5.8 years (range 3 months to 22 years). RESULTS Nine patients had 12 subsequent operations for hemodynamically significant subaortic obstruction. The mean age at PAVSD repair was 17 months (3 to 42 months) (p < 0.001 compared with others). Follow-up work-up was obtained due to symptoms in 5 patients and an abnormal echocardiogram in 4 asymptomatic patients. Subaortic stenosis developed at a mean of 5 years (range 4 months to 10 years), and 6 or more years in 4 patients. The mean age at subaortic stenosis repair was 6 years (range 2 to 12 years). Nine patients underwent subaortic fibromuscular resection. Of these, 4 developed recurrent stenosis and 2 have undergone additional operations. CONCLUSIONS Left ventricular outflow tract obstruction after PAVSD repair may be more frequent than reported. Because of the progressive nature of the process, echocardiography should be utilized liberally on patients to uncover subclinical stenosis. Long-term follow-up is essential for diagnosis due to delayed appearance and lack of reliable clinical signs.

Abstract
BACKGROUND We sought to determine the clinical profile, operative results, and long-term outcome for adult patients undergoing operations for partial atrioventricular septal defects. METHODS Between 1976 and 1996, 50 adults (mean age, 36.6 +/- 13.2 years) underwent surgery for partial atrioventricular septal defects. Thirty-nine of them underwent primary repair for a substantial left-to-right shunt (> or =1.8), associated with symptoms in 29. The remaining 11 patients had previous atrioventricular septal defect repair in childhood, but required reoperation as adults for severe left atrioventricular valve regurgitation (6), subaortic (3) or mitral (1) stenosis, and a residual atrial shunt (1). RESULTS No patients died in hospital. Of the 39 patients first repaired in adulthood, left atrioventricular valve repair was performed in 37, valve replacement in 1, and no repair in 1. In contrast, left atrioventricular valve replacement was necessary in 2 of the 6 adults undergoing reoperation for left atrioventricular valve regurgitation. At 7 years median follow-up, 8 patients have died (2 from noncardiac causes). Of 42 patients alive in 1997, 39 are New York Heart Association class I or II, and 3 were class III (class improved in 81%). Two patients required left atrioventricular valve replacement (1 week and 5 years after repair, respectively) for valvar failure. CONCLUSIONS Low operative risk and excellent long-term results support repair of partial atrioventricular septal defect in adults.
