Application of Foley balloon catheter in palliative surgery for pulmonary atresia with an intact ventricular septem, with additional cases of pulmonary atresia with ventricular septal defect and tetralogy of Fallot. BMC Cardiovasc Disord 2023; 23:547. [PMID: 37940877 PMCID: PMC10634058 DOI: 10.1186/s12872-023-03587-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2023] [Accepted: 10/29/2023] [Indexed: 11/10/2023] Open
Abstract
BACKGROUND Pulmonary atresia and tetralogy of Fallot can require palliative surgery in the neonatal period due to severe hypoxia; however, limitations of established techniques include high failure rate and need for cardiopulmonary bypass. Herein, right ventricular outflow tract reconstruction on a beating heart using a Foley balloon catheter is described. METHODS A retrospective review of patients who underwent right ventricular outflow tract reconstruction on a beating heart using a Foley balloon catheter at our institution between September 2018 and March 2022 was completed. During the procedure, a Foley balloon catheter was used to occlude the blood from the right ventricular inflow tract. RESULTS Eight patients with pulmonary atresia and intact ventricular septum underwent an off-pump right ventricular outflow tract reconstruction. One patient with pulmonary atresia and ventricular septal defect, and two patients with tetralogy of Fallot underwent an on-pump right ventricular outflow tract reconstruction on a beating heart. The procedures were successful in all patients. Patent ductus arteriosus ligation without modified Blalock-Taussig shunt placement was performed in three patients with pulmonary atresia with intact ventricular septum and two patients with tetralogy of Fallot, ductus arteriosus was left open in four patients with pulmonary atresia with intact ventricular septum. All patients remained clinically well without serious complications. CONCLUSIONS Right ventricular outflow tract reconstruction on a beating heart using a Foley balloon catheter for pulmonary atresia and tetralogy of Fallot is a feasible alternative to catheter-based interventions or traditional surgical treatment, especially in patients with muscular infundibular stenosis or hypoplastic pulmonary annulus. Further studies with more cases are needed to verify feasibility and superiority of this approach.

Abstract
Newborns with congenital heart disease often require interventions linked to high morbidity and mortality rates. In the last few decades, many transcatheter interventions have become the first-line treatments for some critical conditions in the neonatal period. A catheter-based approach provides several advantages in terms of procedural time, length of hospitalization, repeatability and neurodevelopmental issues (usually related to cardiopulmonary bypass). The main transcatheter procedures will be reviewed, as they are now valid alternatives to conventional surgical management.

Abstract
Here, we report two neonates diagnosed with pulmonary atresia with intact ventricular septum and muscular right ventricular outflow tract (RVOT) obstruction who underwent modified hybrid therapy as an initial palliation. This new approach combined the traditional hybrid approach and off-pump RVOT reconstruction with a Foley balloon catheter. Both patients recovered well with adequate pressure gradients over the RVOT and pulmonary valve. This novel modified hybrid therapy can serve as a feasible treatment approach for pulmonary atresia patients with intact ventricular septum, especially those with muscular RVOT stenosis. Pulmonary atresia with intact ventricular septum (PA/IVS) is a rare cyanotic congenital cardiac defect that typically requires early decompression of the right ventricle (RV) [1, 2]. Hybrid therapy, namely, transventricular balloon pulmonary valvuloplasty, has emerged as a promising alternative to traditional cardiac surgical procedures or catheter-based techniques [3-5]. However, the saturation of hemoglobin with oxygen (SpO2) does not return to the normal range immediately after the right ventricle outflow tract (RVOT) obstruction is relieved by the hybrid approach. Herein, we describe the effectiveness of a modified hybrid approach in neonatal PA/IVS patients with muscular RVOT obstruction.

Abstract
INTRODUCTION Pulmonary atresia with intact ventricular septum and critical pulmonary stenosis in newborns encompasses a wide spectrum of disease, including cases with significant right ventricular hypoplasia and coronary artery to right ventricle fistulae, which may be considered a contraindication for decompression of the right ventricle. The aim of this study was to review the middle- and long-term outcomes of these patients over 20 years and identify differential factors between both groups, including patients with coronary artery fistulae. PATIENTS AND METHODS We performed a descriptive retrospective study by identifying all patients that received a diagnosis of pulmonary atresia with intact ventricular septum and critical pulmonary stenosis between January 1996 and January 2018. We collected and analysed data regarding right ventricular morphology, surgical management, percutaneous intervention and medium- and long-term outcomes. RESULTS 51 patients were admitted. A total of 9 patients (17.6%) died during the followup. None of the deceased patients had coronary artery to right ventricle fistulae. The median length of follow up in the 42 survivors was 8.9 years (1-16). The functional class based on the latest revision of the New York Heart Association classification was 1.2 for the overall sample. Survivors of critical pulmonary stenosis had a functional class of 1.1, and survivors of pulmonary atresia with intact ventricular septum a functional class of 1.6. There were no differences based on the presence or absence of coronary artery to right ventricle fistulae. CONCLUSIONS Coronary artery to right ventricle fistulae may not be a contraindication for biventricular strategy. Patients with critical pulmonary stenosis had better outcomes compared to patients with pulmonary atresia with intact ventricular septum. The aggressive strategy of opening the pulmonary valve early on was associated with a good overall survival and correlated to a good functional class.

Abstract
There is paucity of long-term data on adult survivors after biventricular repair of pulmonary atresia with intact ventricular septum (PAIVS) and pulmonary stenosis (PS). This study aimed to determine the cardiac and non-cardiac outcomes of adult survivors after biventricular repair of PAIVS and PS. The cardiac, neurodevelopmental and liver problems of 111 adults, 40 with PAIVS and 71 with PS, were reviewed. The median follow-up duration of our patients was 26.5 years (range 14.8-55 years). The freedom from reintervention at 30 years was 17.4% and 73.3% for PAIVS and PS patients (p < 0.001), respectively. Compared with PS patients, PAIVS patients had significantly greater prevalence of right atrial and right ventricular (RV) dilatation, and moderate to severe tricuspid and pulmonary regurgitation (all p < 0.05), and cardiac arrhythmias (22.5% vs. 8.5%, p = 0.047). The freedom from development of cardiac arrhythmias at 30 years of 68.4% and 91.6%, respectively, in PAIVS and PS patients (p = 0.03). Cox proportional hazards model identified PAIVS as an independent risk factor for reintervention (HR 4.0, 95% CI 2.1-7.6, p < 0.001) and development of arrhythmias (HR 4.1, 95% CI 1.1-14.4, p = 0.03). Neurodevelopmental problems were found in 17.5% of PAIVS patients and 7.0% of PS patients (p = 0.11). Liver problems occurred in 2 (5%) PAIVS patients, both of whom required conversion to 1.5 ventricular repair. In conclusion, long-term problems, including the need for reinterventions, cardiac arrhythmias, RV dilation, pulmonary regurgitation, and neurodevelopmental and liver issues are more prevalent in adult PAIVS than PS survivors.

Abstract
BACKGROUND In the present study, we summarize the experiences and evaluate clinical outcomes for the delayed diagnosis of pulmonary atresia with intact ventricular septum (PAIVS) patients when undergoing an initial visit and diagnosis in our heart center. METHODS Fifty-eight cases of delayed diagnosis of PAIVS in patients aged more than 6 months between January 2006 and June 2016 were reviewed in our hospital. The median age at initial diagnosis was 12.2 months (range, 6.1-79.6 months). Forty-five cases eventually reached definitive repair. Survival, risk factors for death, and clinical status after definitive repair were assessed. RESULTS Among patients who completed definitive repair, the Fontan procedure was performed in a large proportion of older PAIVS children (42.2%, 19/45), while only a few patients received biventricular repair (22.2%, 10/45). The medium-term (10-year) survival rates of biventricular repair, 1.5-ventricular repair, and univentricular palliation were 100.0%, 93.3%, and 81.2%, respectively. At the latest follow-up, most patients had a good clinical status after definitive repairs, with a low re-operation rate. CONCLUSIONS A large proportion of the delayed diagnosis of PAIVS patients had to receive univentricular palliation because of limited potential for right ventricular growth. However, optimal definitive repairs could also have been achieved in these patients with a low mortality rate.

Abstract
Valvar pulmonary atresia is a rare congenital anomaly usually associated with ventricular septal defects or intact ventricular septum. The patent ductus arteriosus (56%) and systemic pulmonary collaterals maintain pulmonary blood flow. Presentation beyond childhood is unusual, as there is usually high morbidity in the first year of life. The two index cases highlight the rarity of adolescents with valvar pulmonary atresia and focusses on the transthoracic echocardiographic features, whose diagnoses provide definitive and curative options with adequate size pulmonary dimensions. Options available are transcatheter interventional radiofrequency pulmonary valvotomy, which is both diagnostic and therapeutic, and intraoperative valve replacement, thus eliminating the need for right ventricle pulmonary artery external valved conduit during corrective surgery. They are the first cases of adolescents with isolated cardiac anomaly of valvar pulmonary atresia, documented in Afro-Caribbeans.

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
BACKGROUND This was a study to evaluate the safety and feasibility of balloon valvuloplasty of the pulmonary valve through the right ventricle (RV) for the treatment of pulmonary atresia with intact ventricular septum (PA-IVS). METHODS Ten neonates with PA-IVS, who underwent balloon valvuloplasty of the pulmonary valve through the RV at our institution from January 2008 to May 2010, were enrolled in this study. The oxygen saturation range was 60% to 83% (median 76%). The Z-value range of the tricuspid valve annulus was -2 to 2 (median 0.15), the diameter range of the pulmonary valve annulus was 4.6 to 8.6 mm (median 7.3), and the RV systolic pressure range was 88 to 124 mm Hg (median 106.5). A guidewire was used to perforate the pulmonary valve through the RV, followed by balloon dilation of the valve. The procedure was guided by transesophageal echocardiography. RESULTS The procedure was carried out successfully in all patients. The procedure time ranged from 64 to 110 minutes (median 82.5). Mechanical ventilation time ranged from 8 to 36 hours (median 11), and hospital stay ranged from 7 to 13 days (median 9). After the procedure, the median oxygen saturation increased to 89.5%, the median RV systolic pressure decreased to 45 mm Hg, and the gradient across the pulmonary valve ranged from 20 to 45 mm Hg (median 27.5). Minor complications included transient supraventricular tachycardia (n = 1), blood loss requiring transfusion (n = 2), moderate pulmonary regurgitation (n = 1), and mild pulmonary regurgitation (n = 3). There were no cases of cardiac perforation, main pulmonary artery aneurysm, or low output syndrome. Follow-up of patients ranged from 8 to 15 months (median 12.3). All patients remained clinically well. CONCLUSIONS Balloon valvuloplasty of the pulmonary valve through the RV is a safe and feasible alternative to surgical valvotomy or percutaneous balloon dilation. Early results are encouraging.

Decreased incidence of right-ventricular outflow tract complications using a retrograde snare technique for radiofrequency pulmonary valve perforation. Pediatr Cardiol 2012; 33:1275-80.

Abstract
Perforation of the atretic pulmonary valve with balloon dilation in infants with pulmonary atresia with intact ventricular septum (PA-IVS) is standard initial therapy for right-ventricular (RV) decompression. This procedure often results in adequate pulmonary blood flow, thus eliminating the need for neonatal surgery. Nonetheless, the incidence of RV outflow-tract complications and mortality for this intervention is significant. We report our experience with retrograde snare-guided radiofrequency (RF) perforation in an attempt to improve accuracy and decrease procedural complications. Medical records were reviewed for the period between March 2007 and May 2010 for all patients with PA-IVS who presented to the catheterization laboratory for attempted RF perforation in infancy. Specific details reviewed included demographics, preprocedural echocardiographic (echo) data, procedural technique and complications, pre- and post-RV pressures and pulmonary valve gradients, need for surgical intervention in the neonatal period, and short- to medium-term follow-up. Eleven neonates with PA-IVS underwent RF perforation using a retrograde snare-guided technique during the study period. The pulmonary valve was successfully perforated and the wire snared in all 11 patients. Six of 11 atretic valves were crossed on the first attempt with low energy (5 W × 2 s). No episodes of tamponade or RV/PA perforation occurred as confirmed by echocardiogram performed immediately after the procedure. There was no ductal spasm with retrograde catheter manipulations. Sequential dilation of the perforated valve was not necessary. RV pressures decreased from 169 % systemic before dilation to 93 % after dilation (p < 0.001) with a residual pulmonary valve gradient of 16 ± 6 mm Hg. Eight of 11 patients (73 %) were discharged without surgery at an average 16 days after the intervention. Three patients required Blalock-Taussig shunts to augment pulmonary blood flow. Femoral artery thrombus occurred in 4 of 11 patients treated with anticoagulation, and 2 patients had atrial arrhythmias during the procedure. No other complications occurred. No preprocedural echo parameters predicted requirement for surgical shunt before hospital discharge. Retrograde snare-guided pulmonary valve perforation in infants with PA-IVS is safe and may decrease the incidence of significant procedural complications.

OBJECTIVES To determine the impact of fetal echocardiography on the management of pregnancy and of newborns affected by pulmonary atresia and intact ventricular septum (PAIVS) and to evaluate the outcome of infants with and without prenatal diagnosis of PAIVS. METHODS We searched our database for cases of PAIVS prenatally and postnatally diagnosed during the period January 1993-December 2009. Postnatal follow-up was available in all cases included in the study. Karyotyping and fluorescent in situ hybridization analysis for the DiGeorge critical region (22q11.2) were performed in all but one case. RESULTS The study comprised 60 cases of PAIVS: 36 with (Group A) and 24 without (Group B) prenatal diagnosis. In Group A, there were two intrauterine deaths, six postnatal deaths (five early after birth) and one termination of pregnancy. In this group, radiofrequency (RF) perforation was successfully performed in 25 cases; 20/25 infants had a biventricular (BV) repair, without further operation in 13 of them. No patient of Group B died. In this group, RF perforation was successfully performed in 22 cases; 20/22 had a BV repair without further procedure in 15 of them. CONCLUSIONS Prenatal diagnosis of PAIVS allows a reliable prognosis of severity and planning of proper surgical repair strategies. Fetuses that are prenatally diagnosed present a more severe spectrum of the disease; for the cases capable of getting through the neonatal period, the mortality rate and the need for further intervention were not significantly different when compared with babies with only postnatal diagnosis.

Abstract
Pulmonary atresia and critical pulmonary stenosis with intact ventricular septum includes a wide spectrum of cardiopathies with great morphological heterogeneity. The pulmonary valve may be completely atretic or may contain a puncture hole if stenosis is present. The obstruction may be membranous and/or muscular. All components of the right ventricle can be affected, even the coronary circulation with ventriculocoronary connections and stenosis or atresia of the pulmonary arteries. Prenatal diagnosis is made when the right ventricle is hypoplastic and hypertrophic. The pulmonary valve is thickened and the pulmonary artery is perfused retrogradely through the ductus arteriosus. Right ventriculocoronary connections may sometimes be seen with fetal echocardiography. Postnatal survival depends on the patency of the ductus arteriosus, requiring prostaglandin E1 infusion. When hypoplastic right ventricle and/or ventricle-dependent coronary circulation exists, biventricular circulation is not possible. In these cases, surgical treatment is palliative. In cases with well-developed right ventricle, transcatheter therapy is usually provided with perforation and balloon dilation of the pulmonary valve. In cases of muscular obstruction of the right ventricle outflow tract, surgery may be considered as first-line therapy. In case of prenatal diagnosis, the medical termination of pregnancy is possible when severe right ventricular hypoplasia exists, precluding biventricular circulation. Postnatally, the prognosis of the patients is highly variable, mainly related to the size of the right cavities and the presence of coronary anomalies.

Abstract
BACKGROUND The hypertrophic myocardium, myocardial fiber disarray, and endocardial fibroelastosis in pulmonary atresia and intact ventricular septum (PAIVS) may provide anatomic substrates for restrictive filling of the right ventricle. HYPOTHESIS Restrictive right ventricle (RV) physiology is related to RV fibrosis and exercise capacity in patients after biventricular repair of PAIVS. METHODS A total of 27 patients, age 16.5 +/- 5.6 years, were recruited after biventricular repair of PAIVS. Restrictive RV physiology was defined by the presence of antegrade diastolic pulmonary flow and RV fibrosis assessed by late gadolinium enhancement (LGE) cardiac magnetic resonance. Their RV function was compared with that of 27 healthy controls and related to RV LGE score and exercise capacity. RESULTS Compared with controls, PAIVS patients had lower tricuspid annular systolic and early diastolic velocities, RV global longitudinal systolic strain, systolic strain rate, and early and late diastolic strain rates (all P < 0.05). A total of 22 (81%, 95% confidence interval: 62%-94%) PAIVS patients demonstrated restrictive RV physiology. Compared to those without restrictive RV physiology (n = 5), these 22 patients had lower RV global systolic strain, lower RV systolic and early diastolic strain rates, higher RV LGE score, and a greater percent of predicted maximum oxygen consumption (all P < 0.05). CONCLUSION Restrictive RV physiology reflects RV diastolic dysfunction and is associated with more severe RV fibrosis but better exercise capacity in patients after biventricular repair of PAIVS.

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
OBJECTIVE We sought to identify in utero predictors of postnatal outcomes in fetal patients with pulmonary atresia with intact ventricular septum (PAIVS) or critical pulmonary stenosis. BACKGROUND Although PAIVS or critical pulmonary stenosis can be diagnosed in utero by echocardiography, our ability to predict outcomes is limited. METHODS Fetal echocardiograms from 28 patients with PAIVS/critical pulmonary stenosis were retrospectively reviewed. Tricuspid valve (TV) annulus, right and left ventricular internal dimensions, and degree of tricuspid regurgitation were recorded. To establish normal fetal values, echocardiograms from healthy patients were analyzed in an identical fashion. RESULTS Both a fetal TV z score of -4 or less beyond 23 weeks of gestation and a fetal TV annulus of 5 mm or less beyond 30 weeks of gestation were predictive of poor postnatal outcomes. In addition, right:left ventricular length or width less than 0.5 and/or the absence of tricuspid regurgitation were predictive of poor outcome. CONCLUSIONS TV annulus size, right:left ventricular ratios, and presence of tricuspid regurgitation on fetal echocardiograms may aid in guiding prenatal counseling regarding postnatal outcome in PAIVS.

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
Pulmonary atresia with intact ventricular septum (PAIVS) is a disease with remarkable morphologic variability, affecting not only the pulmonary valve but also the tricuspid valve, the RV cavity and coronary arteries. With advances in interventional techniques and congenital heart surgery, the management of PAIVS continues to evolve. This review is an attempt at providing a practical approach to the management of this disease. The basis of our approach is morphologic classification as derived from echocardiography and angiography. Group A, patients with good sized RV and membranous atresia, the primary procedure at presentation is radiofrequency (RF) valvotomy. Often it is the only procedure required in this group with the most favourable outcome. Patients with severely hypoplastic RV (Group C) are managed along the lines of hearts with single ventricle physiology. The treatment at presentation is patent ductus arteriosus (PDA) stenting with balloon atrial septostomy or conventional modified Blalock Taussig (BT) shunt. Bidirectional Glenn shunt may be done 6-12 months later followed by Fontan completion after a suitable interval. Patients in Group B, the intermediate group, are those with borderline RV size, usually with attenuated trabecular component but well developed infundibulum. The treatment at presentation is RF valvotomy and PDA stenting +/- balloon atrial septostomy. Surgical re-interventions are not uncommonly required viz. bidirectional Glenn shunt when the RV fails to grow adequately (11/2 - ventricle repair) and right ventricular outflow tract (RVOT) reconstruction for subvalvar obstruction or small pulmonary annulus. Catheter based interventions viz. repeat balloon dilatation or device closure of patent foramen ovale (PFO) may also be required in some patients.
