Abstract
BACKGROUND The optimal approach to patent ductus arteriosus management during systemic-to-pulmonary artery shunt placement is currently unknown. The purpose of this study is to examine the outcomes of variable strategies for patent ductus arteriosus management during Blalock-Taussig-Thomas shunt surgery. METHODS A retrospective cohort study of infants who underwent shunt placement was performed, comparing those who had the ductus ligated with those who had the ductus left open. Indicators of low cardiac output syndrome, development of necrotizing enterocolitis, and secondary outcomes such as resuscitation events were examined. RESULTS Thirty-six infants were included all of whom had their shunt placed via median sternotomy. Twenty infants had their ductus ligated at the time of the shunt, and they were compared with 16 infants whose ductus was left open. There was no statistical difference in preoperative baseline characteristics, including corrected gestational age, age in days, weight, mechanical ventilation, vasoactive use, heterotaxy, and gastrointestinal anomalies. There was also no statistical difference in postoperative indicators of low cardiac output, including urine production, total fluids given, renal injury, maximum lactate, and vasoactive-inotropic score. Three patients had postoperative renal injury, and all were in the ligated duct group. There was also no statistical difference in any secondary outcomes, including the development of necrotizing eneterocolitis, resuscitation events, reinterventions, length of intubation, total length of stay, and mortality. CONCLUSIONS This study provides evidence that variable management of the ductus during shunt placement does not significantly impact outcomes. Leaving the ductus open allows for a potential rescue source of pulmonary blood flow and does not appear to increase the risk of postoperative low cardiac output.

Hypoplastic Left Heart Syndrome with Mitral Stenosis and Aortic Atresia-Echocardiographic Findings and Early Outcomes. J Am Soc Echocardiogr 2024; 37:603-612. [PMID: 38432347 DOI: 10.1016/j.echo.2024.02.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2023] [Revised: 02/13/2024] [Accepted: 02/13/2024] [Indexed: 03/05/2024]
Abstract
BACKGROUND Mitral stenosis/aortic atresia (MS/AA) has been reported as a high-risk variant of hypoplastic left heart syndrome (HLHS), potentially related to ventriculocoronary connections (VCCs) or endocardial fibroelastosis (EFE) and myocardial hypoperfusion. We aimed to identify echocardiographic and clinical factors associated with early death or transplant in this group. METHODS Patients with HLHS MS/AA treated at our center between 2000 and 2020 were included. Pre-stage I palliation echocardiograms were reviewed. Certain imaging factors, such as determination of VCC, EFE, and measurement of tricuspid annular plane systolic excursion were measured from retrospective review of preoperative images; others were derived from clinical reports. Groups were compared according to primary outcome of death or transplant prior to stage II palliation. RESULTS Of 141 patients included, 39 (27.7%) experienced a primary outcome. Ventriculocoronary connections were identified in 103 (73.0%) patients and EFE in 95 (67.4%) patients. Among imaging variables, smaller ascending aorta size (median, 2.2 [interquartile range (IQR) 1.7-2.8] vs 2.6 [2.2-3.4] mm, P = .01) was associated with primary outcome. There was similar frequency of VCC (74.4% vs 72.5%, P = .83), EFE (59.0% vs 72.5%, P = .19), moderate or greater tricuspid regurgitation (5.1% vs 5.9%, P = 1.00), and similar right ventricular systolic function (indexed tricuspid annular plane systolic excursion 32.5 ± 7.3 vs 31.4 ± 7.2 mm/m2, P = .47) in the primary outcome group compared to other patients. Clinical factors associated with primary outcome included lower birth weight (mean, 2.8 ± SD 0.8 vs 3.3 ± 0.5 kg, P = .0003), gestational age <37 weeks (31.6% vs 4.9%, P < .0001), longer cardiopulmonary bypass time (median, 112 [IQR, 93-162] vs 82 [71-119] minutes, P = .001), longer intensive care unit length of stay (median, 19 [IQR, 10-30] vs 10 [7-15] days, P = .001), and extracorporeal membrane oxygenation following stage I palliation (43.6% vs 8.8%, P < .0001). Presence of VCCs and EFE was not associated with death or transplant after controlling for birth weight and era of stage I palliation. CONCLUSIONS In one of the largest reported single-center cohorts of HLHS MS/AA, there were few pre-stage I palliation imaging characteristics associated with primary outcome. Imaging findings evaluated in this study, including the presence of VCC and/or EFE as determined using highly sensitive echocardiogram criteria, should not preclude intervention, although impact on long-term outcomes requires further evaluation.

Abstract
Various transcatheter interventions for the right ventricular outflow tract (RVOT) have been introduced and developed in recent decades. Transcatheter pulmonary valve perforation was first introduced in the 1990s. Radiofrequency wire perforation has been the approach of choice for membranous pulmonary atresia in newborns, with high success rates, although complication rates remain relatively common. Stenting of the RVOT is a novel palliative treatment that may improve hemodynamics in neonatal patients with reduced pulmonary blood flow and RVOT obstruction. Whether this option is superior to other surgical palliative strategies or early primary repair of tetralogy of Fallot remains unclear. Transcatheter pulmonary valve replacement has been one of the biggest innovations in the last two decades. With the success of the Melody and SAPIEN valves, this technique has evolved into the gold standard therapy for RVOT abnormalities with excellent procedural safety and efficacy. Challenges remain in managing the wide heterogeneity of postoperative lesions seen in RVOT, and various technical modifications, such as pre-stenting, valve ring modification, or development of self-expanding systems, have been made. Recent large studies have revealed outcomes comparable to those of surgery, with less morbidity. Further experience and multicenter studies and registries to compare the outcomes of various strategies are necessary, with the ultimate goal of a single-step, minimally invasive approach offering the best longer-term anatomical and physiological results.

Abstract
PURPOSE OF REVIEW To review preoperative assessment and management of neonates with congenital heart disease (CHD). RECENT FINDINGS The spectrum for neonates with CHD can be wide and complex. An in-depth understanding of their physiology is the first step in assessing their hemodynamics and developing an effective therapeutic strategy. SUMMARY There is significant heterogeneity in the anatomy and physiology in newborns with CHD. Their complex pathophysiology can be simplified into seven basic subtypes, which include systolic dysfunction, diastolic dysfunction, excessive pulmonary blood flow, obstructed pulmonary blood flow, obstructed systemic blood flow, transposition physiology, and single ventricle physiology. It is important to note these physiologies are not mutually exclusive, and this review summarizes the hemodynamic and therapeutic strategies available for the preoperative neonate with CHD.

Abstract
Clinicians caring for neonates with congenital heart disease encounter challenges in clinical care as these infants await surgery or are evaluated for further potential interventions. The newborn with heart disease can present with significant pathophysiologic heterogeneity and therefore requires a personalized therapeutic management plan. However, this complex field of neonatal-cardiac hemodynamics can be simplified. We explore some of these clinical quandaries and include specific sections reviewing the anatomic challenges in these patients. We propose this to serve as a primer focusing on the hemodynamics and therapeutic strategies for the preoperative neonate with systolic dysfunction, diastolic dysfunction, excessive pulmonary blood flow, obstructed pulmonary blood flow, obstructed systemic blood flow, transposition physiology, and single ventricle physiology.

Outcomes of infants with pulmonary atresia with intact ventricular septum listed for heart transplantation: A multi-institutional study. Pediatr Transplant 2022; 26:e14338.

Abstract
BACKGROUND Management of infants with pulmonary atresia/intact ventricular septum (PA/IVS) is variable. Because of higher mortality in more severe forms, heart transplant (HT) is an acceptable approach, but waitlist and post-transplant outcomes are unclear. This study compared outcomes of infants with PA/IVS vs. other single ventricle (SV) anatomies listed for HT. METHODS Data from the Pediatric Heart Transplant Society (1993-2018) were analyzed for survival and risk factors for mortality. RESULTS Of 1617 SV infants, 300 had PA/IVS (19%) and 1317 had other SV (81%). Overall, 1-, 5-, and 10-year survival was higher among PA/IVS (74%, 65%, 61%) versus other SV infants (62%, 54%, 50%, p = .004). While waitlist mortality was similar between groups (p = .09), PA/IVS was an independent predictor of improved waitlist survival (HR 0.68, p = .03), and PA/IVS infants had higher incidence of waitlist removal (8% vs. 5.5%, p = .03), most commonly for being "too well." Post-transplant survival was superior among PA/IVS versus other SV infants (1- and 5-year survival 93% and 81% vs. 80% and 71%, p < .0001). Risk factors for PA/IVS waitlist mortality (2008-2018) included extracorporeal membrane oxygenation and mechanical ventilation. Prior aortopulmonary (AP) shunt among PA/IVS infants was associated with improved waitlist survival. CONCLUSIONS Overall survival among PA/IVS infants listed for HT exceeds that of other SV infants with PA/IVS identified as an independent predictor of improved waitlist and post-transplant survival. Prior AP shunt among listed PA/IVS infants was associated with improved waitlist outcomes, though, which may reflect a listing selection bias.

Abstract
Coronary abnormalities are frequent in pulmonary atresia and intact ventricular septum, mainly in patients with a very diminutive right ventricle. They severely impact on early and late prognosis. We describe an 8-year-old girl who presented with myocardial ischaemia, late after uneventful Fontan completion. The importance of precise delineation of the coronary anatomy upon initial assessment and during follow-up is emphasised.

Abstract
BACKGROUND There are a number of surgical and interventional treatment options for infants with pulmonary atresia with intact ventricular septum (PAIVS). In our practice, we characterize coronary fistulae and interruptions with angiography in the newborn and have developed a strategy to safely decompress the right ventricle in association with ligation of fistulae if necessary. METHODS All infants operated for PAIVS at age < 60 days from 1999 to 2018 were retrospectively studied. Pre- and postoperative variables were collected, angiograms were reviewed, and a territory score was created to grade the severity of coronary abnormalities. This study focused on the subgroup of patients who had early surgical decompression of the right ventricle. RESULTS A total of 77 patients were included, with a mean follow-up of 8.6 years. Of these, 55 (71%) had coronary fistulae, including 28 (36%) with coronary artery interruption. Right ventricular decompression (RVD) was performed in 47 (60.5%) patients. There was no 30-day mortality in those who underwent RVD, whereas 6 (20%) without RVD died within 30 days (P = .003). Ten-year survival was 97.8% and 73.3% for RVD and non-RVD, respectively. In order to prevent coronary steal, 17 patients underwent coronary fistula ligation as their RV was decompressed with 100% early and late survival. CONCLUSION Early and late survival in infants with PAIVS is better if the RV can be decompressed. Coronary fistula ligation with RVD has been introduced without an adverse outcome in selected patients with large fistulae.

Abstract
BACKGROUND Surgical treatment of pulmonary atresia with intact ventricular septum (PA/IVS) in neonates is challenging because of the broad variations of right ventricular (RV) malformations. In this retrospective study, we summarized our 8-y experience in surgical management for neonatal PA/IVS patients. METHODS Thirty-four neonates with PA/IVS between July 1, 2006 and June 30, 2014, were reviewed. Patients were categorized into three groups: mild, moderate, and severe RV hypoplasia according to RV morphology and development. Patients were on regular follow-up for at least 5 y. Overall survival, complications, reinterventions, risk factors for mortality, and health status were evaluated. RESULTS 21 patients (61.8%) were treated with biventricular repair, eight patients (23.5%) with Fontan procedure, and one patient (2.9%) with bidirectional Glenn procedure. There were four postprocedural mortalities and one late death. The 5-y survival rates after final surgical repair for mild, moderate, and severe RV hypoplasia groups were 100%, 100%, and 88.9%, respectively. The reintervention rates were 0% (0/4), 21.4% (3/14), and 55.6% (5/9) for the subgroups, respectively. At the latest follow-up, most patients had a status characterized as New York Heart Association class I (88.9%, 24/27). CONCLUSIONS Surgical management for PA/IVS in neonates should be individualized. Favorable early and long-term outcomes can be achieved in neonatal PA/IVS patients by individualized surgical strategies, regardless of the degree of RV hypoplasia. In spite of potential RV catch-up development, the degree of RV hypoplasia is a factor of paramount importance to assess PA/IVS in neonates.

Abstract
BACKGROUND AND AIMS Suprasystemic pressure waves can damage the coronary arteries resulting in myocardial ischemia and excess early mortality. We aimed to reduce the coronary pressure wave through the sinusoids by abolishing RV volume with percutaneous devices. METHODS AND RESULTS Four patients with PA-IVS and coronary sinusoids from the hypertensive rudimentary RV were evaluated at a median age 26.6 months (range: 2.7-51.7). Right ventricle coronary dependent flow to the left ventricular myocardium was excluded. All four patients had dual perfusion with competitive flow from the RV through the sinusoids to the coronary arteries. Devices used were: Amplatzer vascular plug II of 10-16 mm; 27 coils (diameter 5-15 mm) in the oldest patient. Right ventricular angiography after cavity obliteration showed no more significant coronary perfusion through the sinusoids. There were no complications or deaths. Only minor and transient changes in the levels of troponin were observed. Coronary angiography at pre-Fontan evaluation showed no progress of coronary abnormalities in two patients. CONCLUSION In selected patients with functionally single left ventricle, obliteration of the hypertensive RV cavity by percutaneous devices is safe and abolishes the systolic pressure wave in coronary sinusoids. When performed early, this may halt coronary damage and avoid excess mortality.

Abstract
OBJECTIVES The specific outcomes of patients with pulmonary atresia with intact ventricular septum late after Fontan palliation are unknown. Patients with smaller right ventricles and myocardial sinusoids are known to have worse survival in the first years of life. Whether the potential for coronary ischaemia affects the long-term outcomes of these patients after Fontan palliation is still unknown. METHODS All patients with pulmonary atresia with intact ventricular septum who underwent the Fontan procedure from 1984 to 2016 in Australia and New Zealand were identified, and preoperative, perioperative and follow-up data were collected. RESULTS Late follow-up data were available for 120 patients. The median length of follow-up after the Fontan procedure was 9.1 years (interquartile range 4.2-15.4 years). Late death occurred in 9% of patients (11/120). Six were sudden, unexpected deaths; 4 of those occurred in patients known to have right ventricle-dependent coronary circulation (RVDCC). Those with RVDCC had a higher incidence of sudden death (4/20 vs 2/100; P = 0.007). RVDCC was associated with late death (P = 0.01) and the development of myocardial ischaemia after Fontan completion (P < 0.001). The 10-year survival rate was 77% (95% confidence interval 56-100%) for patients with RVDCC vs 96% (95% confidence interval 92-100%) for patients without RVDCC. CONCLUSIONS Long-term survival of patients with pulmonary atresia with intact ventricular septum after the Fontan procedure is excellent, but patients with RVDCC remain susceptible to coronary ischaemia and sudden death. Closer surveillance and investigation for exercise-induced ischaemia may be necessary.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2019; 53:512-519. [PMID: 30043402 PMCID: PMC6353696 DOI: 10.1002/uog.19183] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/09/2018] [Revised: 05/30/2018] [Accepted: 07/17/2018] [Indexed: 05/25/2023]
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
OBJECTIVE Pulmonary atresia with intact ventricular septum (PA/IVS) can be treated by various operative and catheter-based interventions. We aim to understand the long-term transplant-free survival of patients with PA/IVS by treatment strategy. METHODS Cohort study from the Pediatric Cardiac Care Consortium, a multi-institutional registry with prospectively acquired outcome data after linkage with the National Death Index and the Organ Procurement and Transplantation Network. RESULTS Eligible patients underwent neonatal surgery or catheter-based intervention for PA/IVS between 1982 and 2003 (median follow-up of 16.7 years, IQR: 12.6-22.7). Over the study period, 616 patients with PA/IVS underwent one of three initial interventions: aortopulmonary shunt, right ventricular decompression or both. Risk factors for death at initial intervention included earlier birth era (1982-1992), chromosomal abnormality and atresia of one or both coronary ostia. Among survivors of neonatal hospitalisation (n=491), there were 99 deaths (4 post-transplant) and 10 transplants (median age of death or transplant 0.7 years, IQR: 0.3-1.8 years). Definite repair or last-stage palliation was achieved in the form of completed two-ventricle repair (n=201), one-and-a-half ventricle (n=39) or Fontan (n=96). Overall 20-year survival was 66%, but for patients discharged alive after definitive repair, it reached 97.6% for single-ventricle patients, 90.9% for those with one-and-a-half ventricle and 98.0% for those with complete two-ventricle repair (log-rank p=0.052). CONCLUSIONS Transplant-free survival in PA/IVS is poor due to significant infantile and interstage mortality. Survival into early adulthood is excellent for patients reaching completion of their intended path independent of type of repair.

Abstract
OBJECTIVES In patients with pulmonary atresia with an intact ventricular septum (PA/IVS), there are no reports about the impact of sinusoidal communication (SC) on left ventricular (LV) performance after a Fontan operation; therefore, the purpose of this study was to fill this gap in the literature. METHODS We performed a single-centre, retrospective study of 46 patients with PA/IVS. Nineteen patients who underwent the Fontan procedure were enrolled and divided into 2 groups: those with SC (SC group) and those without SC (N group). The 2 groups were compared in terms of postoperative cardiac function. RESULTS Thirteen patients were in the SC group (4 patients with right ventricle-dependent coronary circulation) and 6, in the N group. Although 2 of the patients with right ventricular (RV)-dependent coronary circulation showed focal asynergy of the LV wall, others showed no findings of myocardial infarction. The patients' preoperative age and age during the observation period after the Fontan operation did not differ. There was no difference in LV ejection fraction, cardiac index and RV and pulmonary artery pressure before and after the Fontan operation. Preoperative RV volume in the N group was greater than that in the SC group. Brain natriuretic peptide levels were higher in the SC group after the Fontan operation. On ventricular efficacy analysis, contractility was lower (1.8 ± 0.32 vs 2.5 ± 0.40 mmHg/ml/m2, P = 0.001) and ventricular efficacy was worse (1.0 ± 0.15 vs 0.86 ± 0.11, P = 0.046) in the SC group during the postoperative period. CONCLUSIONS Compared to patients with PA/IVS without SC, patients with PA/IVS with SC had a low cardiac contractility and decreased cardiac output efficiency after the Fontan procedure.

Abstract
PA/IVS is a rare, heterogenous congenital heart defect anatomically defined by complete obstruction to the right ventricular outflow tract with varying degrees of hypoplasia of the right ventricle and tricuspid valve. This lesion can have associated coronary artery anomalies and, in some cases, right ventricular-dependent coronary circulation. Due to the wide spectrum of presenting anatomic and clinical features, the treatment options are often dictated by the degree of development of the tricuspid valve and right ventricle. The purpose of this review is to discuss the spectrum of pulmonary atresia with intact ventricular septum morphologies and to evaluate the surgical decision-making process and approaches to surgical repair with respect to the impact of hypoplastic right-sided cardiac features.

Abstract
Although patent ductus arteriosus is essential in fetal life, interventions to close or minimize the adverse hemodynamic effects associated with the left-to-right shunt are often needed after birth, especially in extremely premature infants. However, there are clinical conditions where maintaining patency of the ductus is essential for survival. In this article we discuss use of prostaglandin E1 in the management of congenital heart defects, pulmonary hypertension and left ventricular failure in early neonatal period.

Predictors of Mortality in Children with Pulmonary Atresia with Intact Ventricular Septum. Pediatr Cardiol 2017; 38:1627-1632.

Abstract
Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare cardiac congenital lesion characterized by imperforate pulmonary valve, intact ventricular septum, and atrial level shunt. Although different management strategies to establish a source of non-ductal dependent pulmonary blood flow have been described, studies have not assessed the relationship between the therapeutic approach, patient characteristics, and outcomes. The purpose of this study was to identify predictors of mortality for patients with PA/IVS. Neonates and children with PA/IVS were identified through analysis of the 2012 Kids' Inpatient Database of the Healthcare Cost and Utilization Project. Hospital admissions that included a cardiac catheterization and/or surgical procedure were analyzed to identify demographics, co-morbidities, and outcomes. We identified 508 patients with PA/IVS with hospital admissions that included cardiac catheterization (n = 165), surgical procedures (n = 273), or both (n = 70). The incidence of mortality in this cohort was 6.69% (34/508). Univariable analysis demonstrated that age less than 12 months (p < 0.001), non-elective admission (p < 0.001), AKI (p = 0.001), sepsis (p = 0.002), and the use of ECMO (p < 0.001) were associated with an increased risk of mortality, while no difference was observed for the type of therapeutic approach (p = 0.498). These variables were used in a multivariable logistic regression analysis to develop the predictive model for mortality. Age less than 12 months, non-elective admission, and the use of ECMO in children with PA/IVS were predictors for mortality. Interestingly, the type of therapeutic approach did not influence mortality, which suggests that patient characteristics other than the method chosen to provide pulmonary blood flow determine mortality.

Abstract
PURPOSE OF REVIEW Pediatric heart transplantation is an established therapy for end-stage cardiac disease without suitable medical or surgical options. However, transplantation for congenital heart disease carries an incremental risk that challenges the pediatric transplant team on multiple levels. RECENT FINDINGS With improved outcomes following palliative and corrective congenital cardiac surgery, cardiac transplantation has decreased in recent years as a primary therapy. Nevertheless, congenital heart disease remains the most common indication for cardiac transplantation during infancy. Primary transplantation in infancy is selectively recommended for severe systemic ventricular dysfunction, severe atrioventricular valve insufficiency, and occlusive coronary artery anomalies, particularly with single ventricle physiology. Wait-list mortality remains highest for infants with prior palliative surgery and patients with failing Fontan physiology, both of whom have limited options for effective mechanical circulatory support. The sensitized patient carries an increased risk with prolonged wait times, although virtual cross-matches and single bead assays for donor-specific antigens have facilitated the transplant process. Early and late survival after transplantation for congenital heart disease remain inferior to cardiomyopathy, with prior Fontan procedure as a major risk factor. However, among survivors at 6 months, late outcomes are generally excellent. Major late causes of death include allograft vasculopathy, post-transplant lymphoproliferative disease, and acute rejection. Noncompliance with medications remains a major risk for teenage mortality. SUMMARY Despite the myriad of evolving challenges, pediatric heart transplantation for congenital heart disease enjoys routine short and long-term success at experienced centers for the vast majority of such patients without other options.

Abstract
Pulmonary atresia with intact ventricular septum (PAIVS) is characterized by a broad spectrum of heterogeneous morphologies. Perforation of the atretic valve, balloon dilatation, and stenting of the patent ductus arteriosus are the percutaneous techniques that are used with increasing frequency in our clinic as well. They have some advantages over surgery, including short hospital stay and short intensive care unit stay. The main goal of the primary interventional approach is to avoid surgery. However, a group of patients with PAIVS still need surgery due to poor right ventricular growth. Therefore, the final achievement of the initial percutaneous treatment strategies is still debatable. In this article, we present the early- and mid-term results of the percutaneous approach utilized at our clinic in order to investigate the final effects of interventional therapy according to initial morphology. Between May 2010 and May 2012, 15 neonates diagnosed with PAIVS underwent transcatheter intervention. Detailed echocardiographic examination focused on right ventricle size, and tricuspid valve morphology and coronary sinusoids were performed in all the patients before the intervention. Nine of the patients were boys and six were girls. The mean age was 11.40 ± 12.87 days and mean weight was 3.34 ± 0.46 kg. Only one procedure-related mortality occurred. The mean follow-up period was 10.05 ± 3.42 months (1-26 months). The mean duration of intensive care was 7.19 ± 5.14 days. The mean follow-up time was 10.05 ± 3.42 months. After this period, survival rate was 66% (10/15). Two of the patients achieved biventricular physiology after pulmonary valve perforation. Two patients still have univentricular physiology. Six patients have been followed as a one and half ventricle repair candidate. Five out of 15 patients had stent patency during 6 months of follow-up, while restenosis developed in one patient (1/5, 20%), who had undergone the Glenn operation at 5 months of age. Transcatheter management for PAIVS is a feasible, safe, and effective primary palliative treatment in newborns. Shunt surgery may be considered in cases where cyanosis occurs despite transcatheter intervention. Right ventricular size determines the type of intervention. The early outcomes can be comparable with surgical palliation. However, a group of PAIVS, particularly with severe right ventricular hypoplasia, needs surgery even after a successful primary percutaneous intervention.

Abstract
Heart transplantation is an accepted therapeutic modality for end-stage congenital heart disease for both biventricular and univentricular anomalies. Many transplant centers have pushed the limits of transplantation to include patients with high pulmonary vascular resistance, high panel reactive antibodies, positive cross-matches, and ABO-incompatibility. Excellent results have been possible, particularly with the development of improved diagnostic and therapeutic algorithms to prevent and treat rejection, infection, and post-transplant lymphoproliferative disease. Late graft failure and chronic rejection remain vexing problems. The vast majority of patients with biventricular congenital heart disease have undergone prior cardiac surgical procedures. Indications for transplantation in this subgroup are primarily progressive refractory heart failure following prior cardiac surgical reconstructive procedures. Contraindications to transplantation mimic those for other forms of end-stage heart disease. A determination of pulmonary vascular resistance is important in listing patients with biventricular congenital heart disease for heart transplantation. Modifications in the implant technique are necessary and vary depending on underlying recipient anatomy. Risk factors for perioperative outcomes in patients with biventricular congenital heart disease include the need for reoperation, the degree of anatomic reconstruction necessary during the implant procedure, and the degree of antibody sensitization, in addition to a number of other recipient and donor factors. Postoperative outcomes and survival are very good but remain inferior to those with cardiomyopathy in most series. In conclusion, patients with end-stage biventricular congenital heart disease represent a complex group of patients for heart transplantation, and require careful evaluation and management to ensure optimal outcomes.

Abstract
A neonate with pulmonary atresia and intract ventricular septum, ventriculocoronary sinusoids, bilateral coronary ostial atresia, and a rare collateral vessel between the descending thoracic aorta and the coronary system is described. The clinical course in this infant included extracorporeal life support and coil occlusion of the collateral in order to manage multiple ischemic events.

Critical stenosis of a right ventricle to coronary artery fistula seen at dual-source CT in a newborn with pulmonary atresia and intact ventricular septum. Pediatr Radiol 2011; 41:1069-72.

Abstract
We report the case of a newborn with pulmonary atresia with intact ventricular septum and right ventricle-dependent coronary circulation. He died several weeks after a Blalock-Taussig procedure because of a progressive stenosis of the main coronary artery. We present echocardiographic and dual-source CT images of the stenosis, with autopsy correlation. To our knowledge, CT images of this quality have never been reported in a newborn. This case illustrates the extreme difficulty in prognosticating the outcome for these patients and underlines the need for a detailed neonatal coronary mapping to assess right ventricle-dependent coronary circulation.

Abstract
Neonates born with hypoplastic left heart syndrome now have a remarkably improved prognosis compared with the situation existing before the development of the Norwood sequence of operative procedures. Some of those born with hypoplastic right ventricles in the setting of pulmonary atresia with an intact ventricular septum, however, still have a relatively poor prognosis. In part this reflects the presence of fistulous communication between the cavity of the right hypoplastic right ventricle and the coronary arterial tree. Such fistulous communications are now increasingly recognised as being important in the setting of hypoplastic left heart syndrome. In this brief review, we describe the anatomy of the communications. Those found with hypoplastic right ventricles are seen most frequently when the cavity of the ventricle effectively represents only the inlet, this in turn reflecting mural overgrowth of the apical trabecular and outlet components during foetal development. This almost certainly reflects an earlier appearance of the pulmonary valvar lesion that promotes the cavitary hypoplasia. In those with hypoplastic left ventricles, the key feature differentiating those with fistulous communications is the presence of a patent mitral valve, since the left ventricle is typically no more than a virtual slit in postero-inferior ventricular wall in the setting of mitral valvar atresia or absence of the left atrioventricular connection.

Abstract
This report describes a premature newborn with pulmonary atresia and an intact ventricular septum who presented with a significant fistula between the right ventricle and the left anterior descending coronary artery (LAD). The right ventricle was not decompressed to prevent myocardial damage. After 2 months, the fistula had closed spontaneously. The pulmonary valve was opened, and biventricular circulation was achieved.

Abstract
A stillborn fetus with pulmonary valvar atresia and intact atrial and ventricular septums also had absence of coronary arterial connections from the aorta and an unroofed coronary sinus. A left superior caval vein drained to the dilated coronary sinus. The left coronary artery was anomalously connected to the proximal branch of the right pulmonary artery, and a fistula from the right ventricle supplied the right coronary artery.
