Abstract
BACKGROUND Hybrid interventions have become a common option in the management for a variety of patients with congenital heart disease. In this review, we discuss the data that have driven decision making about hybrid interventions to date. METHODS The existing literature on various hybrid approaches was reviewed and summarized. In addition, the key tenants to creating a successful hybrid program within a congenital heart center are elucidated. RESULTS Hybrid strategies for single-ventricle patients, pulmonary atresia with intact ventricular septum, branch pulmonary artery stenosis, and muscular ventricular septal defect closure have important benefits and limitations compared with traditional approaches. CONCLUSION A growing body of evidence supports the use of hybrid interventions in congenital heart disease. But important questions remain regarding improved survival and other long-term outcomes, such as neurocognition, that might impact widespread adoption as a primary treatment strategy.

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
Radiofrequency (RF) perforation of an atretic pulmonary valve is commonly performed in patients with pulmonary atresia with intact ventricular septum with specifically designed RF wires. In difficult anatomy or low-resource centers, this may instead be successfully performed with a modified coronary guide wire and an electrocautery surgical pencil.

Abstract
Background Pulmonary atresia (PA) is a heterogeneous congenital heart defect and ventricular septal defect (VSD) is the most vital factor for the conventional classification of PA patients. The simple dichotomy could not fully describe the cardiac morphologies and pathophysiology in such a complex disease. We utilized the Human Phenotype Ontology (HPO) database to explore the phenotypic patterns of PA and the phenotypic influence on prognosis. Methods We recruited 786 patients with diagnoses of PA between 2008 and 2016 at Fuwai Hospital. According to cardiovascular phenotypes of patients, we retrieved 52 HPO terms for further analyses. The patients were classified into three clusters based on unsupervised hierarchical clustering. We used Kaplan–Meier curves to estimate survival, the log-rank test to compare survival between clusters, and univariate and multivariate Cox proportional hazards regression modeling to investigate potential risk factors. Results According to HPO term distribution, we observed significant differences of morphological abnormalities in 3 clusters. We defined cluster 1 as being associated with Tetralogy of Fallot (TOF), VSD, right ventricular hypertrophy (RVH), and aortopulmonary collateral arteries (ACA). ACA was not included in the cluster classification because it was not an HPO term. Cluster 2 was associated with hypoplastic right heart (HRH), atrial septal defect (ASD) and tricuspid disease as the main morphological abnormalities. Cluster 3 presented higher frequency of single ventricle (SV), dextrocardia, and common atrium (CA). The mortality rate in cluster 1 was significantly lower than the rates in cluster 2 and 3 (p = 0.04). Multivariable analysis revealed that abnormal atrioventricular connection (AAC, p = 0.011) and persistent left superior vena cava (LSVC, p = 0.003) were associated with an increased risk of mortality. Conclusions Our study reported a large cohort with clinical phenotypic, surgical strategy and long time follow-up. In addition, we provided a precise classification and successfully risk stratification for patients with PA.

Abstract
Right ventricular outflow tract (RVOT) anomalies comprise a wide spectrum of congenital heart disease, typically characterized by obstruction to flow from the right ventricle to pulmonary arteries. This review highlights important considerations surrounding management strategy as well as clinical outcomes for the neonate with RVOT anomaly, including: pulmonary atresia with intact ventricular septum, congenital pulmonary valve stenosis, tetralogy of Fallot, and Ebstein anomaly with anatomic or physiologic RVOT obstruction.

Abstract
BACKGROUND There is increasing use of catheter-based therapy as part of the neonatal treatment algorithm for pulmonary atresia with an intact ventricular septum (PAIVS). The management strategies utilised and outcomes of patients with PAIVS at our centre have not been examined. METHODS A retrospective case series was undertaken including all infants with PAIVS born January 2009 to July 2019 (follow-up to January 2020) managed at The Children's Hospital at Westmead, New South Wales. Demographic features, anatomical substrate, management pathway and subsequent clinical outcomes were examined. RESULTS Fifty-two (52) infants were included (male n=28, 53.8%). The right ventricular morphology was classified as normal, mildly, moderately and severely hypoplastic in 3 (5.8%), 13 (25.0%), 19 (36.5%) and 17 (32.7%) patients respectively. Thirty-seven (37) patients underwent an initial aortopulmonary (AP) shunt (surgical shunt or patent ductus arteriosus [PDA] stent). The remaining 15 patients underwent an initial intervention to decompress the right ventricle. Twenty (20) patients underwent a neonatal catheter-based intervention. An initial catheter-based intervention was more likely in the second half of the period. Sixteen (16) patients had an attempted pulmonary valve perforation, 12 as their initial procedure. Median follow-up was 62 months (range 3-119 months). Final circulation status was known in 37 patients; biventricular n=14 (37.8%), "1.5 ventricles" n=4 (10.8%), single n=19 (51.4%). There were five deaths during the period (9.6%), including two during the initial procedural admission attributed to tamponade requiring extracorporeal membrane oxygenation (ECMO) at the time of percutaneous pulmonary valve perforation. CONCLUSION There has been an overall trend towards including catheter-based strategies in the neonatal period as part of management at our centre. Given the risk of bleeding and ECMO related to this, consideration should be given to the availability of multidisciplinary support when planning the timing of these procedures.

Abstract
Post-procedural right ventricular pseudoaneurysm is a rare but life-threatening complication of interventional catheterisation. We describe a 3-day-old newborn who underwent transcatheter intervention for pulmonary atresia with a complication of right ventricular pseudoaneurysms, and transcatheter embolisation of the pseudoaneurysms was performed at 3-week-old. It is the first described case that receives transcatheter closure of right ventricular pseudoaneurysms in a newborn with a favourable outcome.

Percutaneous Balloon Pulmonary Valvuloplasty of Critical Pulmonary Stenosis and severe pulmonary stenosis in Neonates and Early Infancy: A Challenge in the Cyanotic. J Cardiovasc Thorac Res 2021; 13:156-161. [PMID: 34326970 PMCID: PMC8302899 DOI: 10.34172/jcvtr.2021.33] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Accepted: 04/30/2021] [Indexed: 11/29/2022] Open
Abstract
Introduction: Pulmonary stenosis with an intact ventricular septum (PS-IVS) is one of the common causes of cyanotic heart disease in neonates with diverse morphologies as well as management and treatment protocols. The aim of this study was to evaluate short and midterm results of balloon pulmonary valvuloplasty (BPV) for this disorder. Methods: Between 2012 and 2016, Totally 45 neonates and infants under 6 months old were evaluated.The patients had a minimum right-to-left ventricular pressure ratio of 1, right-to-left shunting at the patent foramen ovale or atrial septal defect level, and tricuspid valve Z-scores higher than -4. Results: Immediately after the procedure, the right ventricular pressure dropped to the normal values in 8 (20%) patients. The immediate procedural success rate was seen in 42 (93.3%) cases: the right-to-left ventricular pressure ratio dropped to below 50% or the level of O2 saturation rose above 75%. Of three cases unresponsive to BPV, two of them underwent patent ductus arteriosus (PDA) stenting and one procedural death occurred. At 6 months’ follow-up, of 42 patients, this pressure was still with in the normal range in 36 (80%) infants, while it had returned to high values in 9 (20%) patients and necessitated repeat valvuloplasty. After BPV, severe pulmonary valve regurgitation was observed in14.2% patients; the condition was more common when high-profile noncompliant balloons were used. Conclusion: Balloon pulmonary valvuloplasty in infants with PS-IVS confers acceptable results insofar as it improves echocardiographic parameters and hemodynamic changes at short- and midterm followups.Balloon selection with sizes more than 1.2 of the diameter of the pulmonary valve annulus and the use of noncompliant high-pressure balloons results in higher degrees of pulmonary regurgitation.

Abstract
BACKGROUND We aimed to explore the relationship between temporal right heart growth and long-term outcomes in patients with pulmonary atresia with intact ventricular septum (PA/IVS) who underwent balloon pulmonary valvulopalsty (BPV). METHODS Echocardiography was performed to measure the pulmonary valve diameter (PVD), the right atrial end-systolic area (RAA), and the right ventricular end-diastolic area (RVA) before BPV, 1 and 5 years after BPV. The primary and secondary endpoints were to explore temporal changes in the right heart structures and to determine echocardiographic parameters related to late adverse events (LAEs). RESULTS In 31 patients, PVD significantly increased after BPV, whereas TVD remained unchanged throughout the follow-up period of 9.1 (5.7-12.0) years. After BPV, RAA temporally decreased, whereas RVA significantly increased. There were six LAEs (19%); arrhythmias in two, heart failure in one, reintervention of the right ventricular outflow tract in one, and reintervention for residual cyanosis in two. The rate of freedom from LAEs at 5 and 10 years were 92% and 82%, respectively. RAA temporally decreased in patients without LAEs (P<0.01); however, RAA remained unchanged throughout the period in patients with LAEs (P=0.16). Moderate or severe pulmonary regurgitation (PR) (hazard ratio [HR], 23.0; 95% confidence interval [CI], 1.3-385; P=0.03) and the ratio of RVA /RAA at 1 year after BPV (HR, 6.3×10-11; 95%CI, 2.1×10-20-0.19; P=0.03) were independent risk factors for LAEs. CONCLUSIONS Disproportional right heart growth was observed in patients with PA/IVS after BPV. PR and increased RAA are crucial in identifying the burden of LAEs among them.

Abstract
OBJECTIVE We report a single-institute experience of neonatal transvenous radiofrequency pulmonary valve perforation for pulmonary atresia/intact ventricular septum, with echocardiographic predictors of biventricular circulation. METHODS Data were reviewed retrospectively for all neonates who underwent primary transvenous pulmonary valve perforation for pulmonary atresia/intact ventricular septum between January 2008 and November 2018 at our institution. We compared patients who need systemic-to-pulmonary shunt or ductal stenting with patients who did not need. RESULTS During the study period, 31 patients with pulmonary atresia/intact ventricular septum underwent successful radiofrequency pulmonary valve perforation and balloon dilation of the pulmonary valve. There was no procedure-related mortality. Sixteen patients (52%) needed systemic-to-pulmonary shunt or ductal stenting after initial procedure. Among the survivors (follow-up time of 1 to 11.5 years), 15 patients had a biventricular circulation and 6 patients had 1 and 1⁄2 ventricular circulation. Two patients are awaiting for Fontan operation. Both the TV/MV annulus ratio (>0.85) and tricuspid valve z-score (>-1) were found to be a good predictor of a biventricular outcome in our cohort. CONCLUSIONS Percutaneous radiofrequency pulmonary valve perforation and balloon valvotomy is an effective and safe primary treatment strategy for neonates with pulmonary atresia/intact ventricular septum. Ductal stenting or systemic-to-pulmonary shunt may be required in the majority of patients who had smaller right heart components. Preselection of patients according to tricuspid valve z-score and TV/MV annulus ratio allows predicting biventricular circulation.

Abstract
Methods and Results We retrospectively reviewed 52 young infants, 41 of whom had CPS and 11 had PA/IVS, in a single center from June 2009 to October 2017. Patients were divided into three groups according to the type of catheter used to enter through the RVOT. The unique structure of the Simmons catheter allowed it to be maneuvered directly into the RVOT within a few minutes. Compared with the other two groups, the Simmons catheter group had a significantly shorter fluoroscopy time entering through the RVOT (P < 0.001) and a shorter total X-ray exposure time (P < 0.001). Furthermore, compared with the floating catheter group, the success rate of surgery was much higher in the Simmons catheter group (P < 0.001). Conclusions The Simmons catheter is a safe and effective method to enter through the RVOT in infants with CPS or PA/IVS. Therefore, the Simmons catheter could be an alternative catheter when entering through the RVOT in young infants, especially neonates with low birth weight.

Abstract
AIMS Management strategies for pulmonary atresia with intact ventricular septum are variable and are based on right ventricular morphology and associated abnormalities. Catheter perforation of the pulmonary valve provides an alternative strategy to surgery in the neonatal period. We sought to assess the long-term outcome in terms of survival, re-intervention, and functional ventricular outcome in the setting of a 26-year single-centre experience of low threshold inclusion criteria for percutaneous valvotomy. METHODS AND RESULTS Retrospective analysis of patients diagnosed with pulmonary atresia with intact ventricular septum from 1990 to 2016 at a tertiary referral centre, was performed. Of 71 patients, 48 were brought to the catheterisation laboratory for intervention. Catheter valvotomy was successful in 45 patients (94%). Twenty-three patients (51%) also underwent ductus arteriosus stenting. The length of intensive care and hospital stay was significantly shorter, and early re-interventions were significantly reduced in the catheterisation group. There were eight deaths (17%); all within 35 days of the procedure. Of the survivors, only one has required a Fontan circulation. Twenty-eight patients (74%) have undergone biventricular repair and nine patients (24%) have one-and-a-half ventricle circulation. Following successful valvotomy, 80% of patients required further catheter-based or surgical interventions. CONCLUSIONS A low threshold for initial interventional management yielded a high rate of successful biventricular circulations. Although mortality was low in patients who survived the peri-procedural period, the rate of re-intervention remained high in all groups.

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
Pulmonary atresia (PA) is a rare congenital heart defect (CHD) with complex manifestations and a high mortality rate. Since the genetic determinants in the pathogenesis of PA remain elusive, a thorough identification of the genetic factors through whole exome sequencing (WES) will provide novel insights into underlying mechanisms of PA. We performed WES data from PA/VSD (n = 60), PA/IVS (n = 20), TOF/PA (n = 20) and 100 healthy controls. Rare variants and novel genes were identified using variant-based association and gene-based burden analysis. Then we explored the expression pattern of our candidate genes in endothelium cell lines, pulmonary artery tissues, and embryonic hearts. 56 rare damage variants of 7 novel candidate genes (DNAH10, DST, FAT1, HMCN1, HNRNPC, TEP1, and TYK2) were certified to have function in PA pathogenesis for the first time. In our research, the genetic pattern among PA/VSD, PA/IVS and TOF/PA were different to some degree. Taken together, our findings contribute new insights into the molecular basis of this rare congenital birth defect.

Abstract
Stenting the arterial duct emerged in the early 1990s as an alternative to a variety of surgical interventions in neonates with a duct-dependent pulmonary or systemic circulation complex defect. Furthermore, palliative ductal stenting has been applied in older children with severe suprasystemic pulmonary arterial hypertension, as an alternative to surgical shunts, such as Potts anastomosis. Early results of this technique were discouraging, but by learning from the failures of the past, ductal stenting has become a reliable palliative therapy. In this review, we aim to describe the historical evolution of ductal stenting, its different clinical applications and outcomes, and future perspectives for this strategy in congenital cardiac catheterization.

Abstract
Recent advances in catheterization and imaging technology allow for more complex procedures to be performed in the catheterization laboratory. A number of lesions are now amenable to a percutaneous procedure, eliminating or at least postponing the need for a surgical intervention. Due to the increase in the complexity of the procedures performed, the involvement of anesthesiologists and their close collaboration with the interventional cardiologists have increased. It is important to understand the physiology and pathophysiology of the patients and to anticipate the plans and the potential complications in order to manage them. We are witnessing a rise in the number of complex interventions in newborns and infants, such as balloon valvotomy (critical aortic stenosis, pulmonary stenosis), radio frequency perforation (of pulmonary atresia and intact ventricular septum), right ventricular outflow tract stenting (in Tetralogy of Fallot), ductal stenting (in some ductus-dependent pulmonary circulation), and combined with a surgical procedure (hybrid procedure for hypoplastic left heart syndrome). Multiple registries have been created in order to understand and improve outcomes of patients with congenital heart disease undergoing catheterization procedures and to develop performance and quality metrics, from which data regarding anesthetic-related risks can be extrapolated. Experienced personnel and a multidisciplinary team approach with direct communication among the team members is a must to ensure anticipation and management of critical events when they occur.

Abstract
OBJECTIVE To assess the feasibility, safety, and efficiency of ductal stenting in pulmonary atresia with intact ventricular septum or critical pulmonary stenosis after balloon pulmonary valvuloplasty. BACKGROUND Ductal stenting in pulmonary atresia with intact ventricular septum is a re-emerging and promising technique. There is little data available on its outcomes after establishing prograde pulmonary blood flow. METHODS We retrospectively reviewed all neonates with pulmonary atresia with intact ventricular septum or critical pulmonary stenosis who underwent ductal stenting after balloon valvuloplasty. Ductal stenting was performed either in the same setting (group A) or a few days later after balloon valvuloplasty (group B). We compared the two groups. RESULTS Eighteen coronary stents were transvenously delivered and successfully deployed in 18 newborns. There was no procedure-related mortality. The median hospital stay post-intervention was 6 days with a mean discharge oxygen saturation of 94%. Group A had a shorter overall hospital stay with a shorter overall time of irradiation but with a longer overall procedural time. On a follow-up of 18 months, no re-intervention for stent failure or overflow was undertaken. The median stent patency based on echocardiography was 12 months. CONCLUSION Stenting the arterial duct in pulmonary atresia with intact ventricular septum or critical pulmonary stenosis is a feasible, safe, and efficient technique. It avoids surgery or long hospital stay with prostaglandin infusion. The minimal 6 months stent longevity provides a period of time long enough to decide whether the right ventricular diastolic function is normalised or Glenn surgery is still needed.

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

Abstract
BACKGROUND In patients with pulmonary atresia, intact ventricular septum (PA/IVS) following right ventricular (RV) decompression, RV size and morphology drive clinical outcome. Our objectives were to (1) identify baseline and postdecompression echocardiographic parameters associated with 2V circulation, (2) identify echocardiographic parameters associated with RV growth and (3) describe changes in measures of RV size and changes in RV loading conditions. METHODS We performed a retrospective analysis of patients who underwent RV decompression for PA/IVS at four centers. We analyzed echocardiograms at baseline, postdecompression, and at follow up (closest to 1-year or prior to Glenn circulation). RESULTS Eighty-one patients were included. At last follow-up, 70 (86%) patients had 2V circulations, 7 (9%) had 1.5 ventricle circulations, and 4 (5%) had single ventricle circulations. Follow-up echocardiograms were available in 43 (53%) patients. The majority of patients had improved RV systolic function, less tricuspid regurgitation (TR), and more left-to-right atrial shunting at a median of 350 days after decompression. Multivariable analysis demonstrated that larger baseline tricuspid valve (TV) z-score (P = .017), ≥ moderate baseline TR (P = .045) and smaller baseline RV area (P < .001) were associated with larger increases in RV area. Baseline RV area ≥6 cm2 /m2 had 93% sensitivity and 80% specificity for identifying patients who ultimately achieved 2V circulation. All patients with RV area ≥8 cm2 /m2 at follow up achieved 2V circulation. This finding was confirmed in a validation cohort from a separate center (N = 25). Factors associated with achieving RV area ≥8 cm2 /m2 included larger TV z-score (P = .004), ≥ moderate baseline TR (P = .031), and ≥ moderate postdecompression pulmonary regurgitation (P = .002). CONCLUSIONS Patients with PA/IVS and smaller TV annuli are at risk for poor RV growth. Volume-loading conditions signal increased capacity for growth sufficient for 2V circulation.

Abstract
BACKGROUND Transcatheter right ventricle decompression in neonates with pulmonary atresia and intact ventricular septum is technically challenging, with risk of cardiac perforation and death. Further, despite successful right ventricle decompression, re-intervention on the pulmonary valve is common. The association between technical factors during right ventricle decompression and the risks of complications and re-intervention are not well described. METHODS This is a multicentre retrospective study among the participating centres of the Congenital Catheterization Research Collaborative. Between 2005 and 2015, all neonates with pulmonary atresia and intact ventricular septum and attempted transcatheter right ventricle decompression were included. Technical factors evaluated included the use and characteristics of radiofrequency energy, maximal balloon-to-pulmonary valve annulus ratio, infundibular diameter, and right ventricle systolic pressure pre- and post-valvuloplasty (BPV). The primary end point was cardiac perforation or death; the secondary end point was re-intervention. RESULTS A total of 99 neonates underwent transcatheter right ventricle decompression at a median of 3 days (IQR 2-5) of age, including 63 patients by radiofrequency and 32 by wire perforation of the pulmonary valve. There were 32 complications including 10 (10.5%) cardiac perforations, of which two resulted in death. Cardiac perforation was associated with the use of radiofrequency (p=0.047), longer radiofrequency duration (3.5 versus 2.0 seconds, p=0.02), and higher maximal radiofrequency energy (7.5 versus 5.0 J, p<0.01) but not with patient weight (p=0.09), pulmonary valve diameter (p=0.23), or infundibular diameter (p=0.57). Re-intervention was performed in 36 patients and was associated with higher post-intervention right ventricle pressure (median 60 versus 50 mmHg, p=0.041) and residual valve gradient (median 15 versus 10 mmHg, p=0.046), but not with balloon-to-pulmonary valve annulus ratio, atmospheric pressure used during BPV, or the presence of a residual balloon waist during BPV. Re-intervention was not associated with any right ventricle anatomic characteristics, including pulmonary valve diameter. CONCLUSION Technical factors surrounding transcatheter right ventricle decompression in pulmonary atresia and intact ventricular septum influence the risk of procedural complications but not the risk of future re-intervention. Cardiac perforation is associated with the use of radiofrequency energy, as well as radiofrequency application characteristics. Re-intervention after right ventricle decompression for pulmonary atresia and intact ventricular septum is common and relates to haemodynamic measures surrounding initial BPV.

Abstract
Patent ductus arteriosus (PDA) stenting has gained acceptance for palliation in cyanotic congenital heart disease. The PDA in tetralogy of Fallot with pulmonary atresia (ToF-PA) arises, in the left aortic arch, from underneath the arch and connects to the proximal left pulmonary artery, often resulting in stenosis. The PDA is usually elongated and tortuous, making stent implantation challenging. Shorter duration of palliation, aggravation of branch pulmonary artery stenosis resulting in poor growth and difficulty at surgery makes ductal stenting controversial. Access via the carotid and axillary artery reduces complexity of the procedure and improves success, with recent data demonstrating good pulmonary artery growth. Advances in bioresorbable stents offer future promise and will likely resolve some controversies surrounding PDA stenting in ToF-PA.

Prenatal Echocardiographic Predictors of Postnatal Management Strategy in the Fetus with Right Ventricle Hypoplasia and Pulmonary Atresia or Stenosis. Pediatr Cardiol 2017; 38:1562-1568. [PMID: 28770306 DOI: 10.1007/s00246-017-1696-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2017] [Accepted: 07/19/2017] [Indexed: 12/19/2022]
Abstract
Fetuses with pulmonary atresia or pulmonary stenosis with intact ventricular septum manifest variable degrees of right ventricle hypoplasia and inadequacy. We studied the relationship between prenatal echocardiographic parameters and their progression through gestation as potential predictors of postnatal single-ventricle or two-ventricle care strategy. Serial fetal echocardiograms of pulmonary atresia (n = 28) or severe pulmonary stenosis (n = 8) and intact ventricular septum were reviewed. Measurements included tricuspid valve and mitral valve diameter and Z scores, degree of tricuspid regurgitation, presence of subaortic stenosis, presence of coronary artery fistulae, and Doppler pulsatility indices in middle cerebral and umbilical artery. Data were compared between first and last fetal studies. Subjects were divided based on postnatal course of single- or two-ventricle repair. Tricuspid valve size of those destined for single ventricle is smaller than of those destined for a two-ventricle repair at first study (26w, Z score -4.22 v -1.83, p < 0.001) and at final study (35w, -4.94 v -1.42, p < 0.001). Tricuspid valve and right ventricle grow in those destined for two ventricle, but not single-ventricle palliation. Tricuspid valve Z score = -3 at first or last study discriminated between single- or two-ventricle repair, except in two unusual cases with significant subaortic stenosis. Tricuspid valve Doppler-derived parameters of middle cerebral artery and umbilical artery did not distinguish between groups. In the fetus with pulmonary atresia or stenosis and intact ventricular septum, tricuspid valve Z score ≥-3, presence of important tricuspid regurgitation, absence of coronary fistulae, and absence of subaortic stenosis are associated with a two-ventricle postnatal strategy.

Abstract
Objective The aim of the study was to assess the feasibility of using commonly available catheterization laboratory equipment for radiofrequency perforation of the pulmonary valve in patients with pulmonary atresia and intact ventricular septum. Methods The system (off-label use for all items) is made up of a co-axial telescopic arrangement consisting of a 0.014" PT 2 ™ coronary guidewire, for insulation inside a 2.7-F microcatheter which has an inner lumen of 0.021". The microcatheter was passed via a standard 4-F right coronary catheter to just below the atretic pulmonary valve. Radiofrequency (RF) energy was delivered using a standard electrosurgical system. In vitro testing had been performed and indicated that 5-10 W for 2-5 s would be sufficient for valve perforation. Results Radiofrequency perforation was successfully performed in all (n = 5, 100%) patients at a median age of 3 days (range: 1-36) and weight 2.7 kg (range 2.3-3.0). In one patient the pericardium was entered during the initial attempt; the generator was put on coagulation mode during retrieval of the guidewire and no haemopericardium occurred. The pulmonary valve was dilated in all; in three patients (n = 3) the ductus arteriosus was stented during the same session. Conclusion Results of the study show that it is feasible to perforate the pulmonary valve safely using this system. Availability, simplicity and cost are noteworthy benefits.

Abstract
Objectives: In the surgical treatment of pulmonary atresia with intact ventricular septum, the size of the tricuspid valve annulus (as measured by z-scores) has emerged as a significant factor in deciding which repair to perform. Various tricuspid valve annulus z-scores are reported as “cutoffs” for successful biventricular repair. We aimed to determine whether the use of different z-score data sets contributed to the gross variation in “cutoffs” for successful biventricular repair reported in the literature. Methods: A single search was made of PubMed using the “advanced” setting with the following search terms: pulmonary, atresia, intact, septum, z, and score. The filters “title” and “title/abstract” were used for the first four and last two terms, respectively; the instruction “AND” combined all terms. Articles that identified which z-score data set was used in patients with biventricular repairs were included. Results: From 13 articles, 1,392 patients were studied, 410 (29.5%) of which achieved biventricular repair. Three z-score data sets were quoted; mean tricuspid valve annulus z-scores in biventricular repair patients ranged between −0.53 and −5.1. After correcting for discrepancies between z-score data sets, no study reported a mean tricuspid valve annulus z-score <−2.8 in biventricular repair patients and 83.3% reported mean tricuspid valve annuli z-scores >−1.7. Conclusion: The use of varied tricuspid valve annuli z-score data sets may have contributed to gross variations in reported “cutoffs” for successful biventricular repair. This could lead to inappropriate surgical pathway allocation.

Outcomes of Radiofrequency Perforation for Pulmonary Atresia and Intact Ventricular Septum: A Single-Centre Experience. Pediatr Cardiol 2017; 38:170-175.

Abstract
Percutaneous radiofrequency perforation (RFP) of the pulmonary valve is used as a primary therapy in neonates with pulmonary atresia and intact ventricular septum (PAIVS). We sought to determine the safety and efficacy of RFP for PAIVS in a single center and assess the pre-intervention anatomical parameters associated with a biventricular outcome. We retrospectively reviewed all cases of PAIVS treated with RFP at a single center from 1999 through 2012. We collected baseline imaging data, technical aspects of the procedure, adverse events and outcomes. RFP was attempted in 18 patients with 17 successful procedures. There was no mortality; one patient had an acute complication requiring surgical intervention. All were alive at the most recent follow-up (median 4.9 years; IQR = 2.0-6.8 years), 12/17 (71%) had a biventricular circulation, 2/17 (12%) had a 1½ ventricle repair, 2/17 (12%) had a univentricular repair and 1/17 was lost to follow-up. A biventricular outcome in patients with PAIVS was associated with the pre-intervention tricuspid valve/mitral valve (TV/MV) ratio and tricuspid valve (TV) z-score. The median TV/MV ratio for patients who underwent a biventricular repair and a non-biventricular repair was 0.82 (IQR = 0.71-0.90) and 0.59 (IQR = 0.39-0.76), P = 0.036, respectively. The median TV z-scores were -3.2 [(-4.9 to -2.6), and -6.8 (-9.7 to -4.8] P = 0.036 for the biventricular and non-biventricular groups, respectively. RFP is a safe primary therapy for PAIVS. With appropriate patient selection, RFP will often result in a biventricular circulation. Both the TV/MV and TV z-score were found to be a predictor of a biventricular outcome in our cohort.

Abstract
Background In patients who have pulmonary atresia with an intact ventricular septum and severe right ventricular hypoplasia, biventricular repair is considered to be impossible and multiple interventions are generally required for definitive repair. Case presentation An initial palliative procedure was performed in a 1-month-old boy to promote right ventricular development by pulmonary valvectomy without disrupting the annulus, and appropriate oxygenation was achieved with a central funnel shunt. The retained annulus caused functional stenosis and prevented unfavorable right ventricular dilatation due to regurgitation. Thirteen years later, without any other intervention, reconstruction of the right ventricular outflow tract was successfully performed for definitive biventricular repair by using a new expanded polytetrafluoroethylene bulging valved conduit with extended longevity. Conclusions The successful outcome in this case suggests that our minimal palliation strategy could be one option for management of these patients.

Abstract
Advances in surgical technique have had an immense impact on longevity and quality of life in patients with congenital heart disease. However, an inevitable consequence of these surgical successes is the creation of a unique patient population whose anatomy, surgical history and haemodynamics result in the development of a challenging and complex arrhythmia substrate. Furthermore, this patient group remains susceptible to the arrhythmias seen in the general adult population. It is through a thorough appreciation of the cardiac structural defect, the surgical corrective approach, and haemodynamic impact that the most effective arrhythmia care can be delivered. Catheter ablation techniques offer a highly effective management option but require a meticulous attention to the real-time integration of anatomical and electrophysiological information to identify and eliminate the culprit arrhythmia substrate. This review describes the current approach to the interventional management of patients with tachyarrhythmias in the context of congenital heart disease.

Abstract
Radiofrequency perforation and valvuloplasty (RFV) is an effective initial treatment in patients with pulmonary atresia and intact ventricular septum (PA-IVS) and mild to moderate right ventricle and tricuspid valve hypoplasia. Outcomes and risk factors for the need for additional interventions in these patients are poorly defined. All patients with PA-IVS who underwent RFV at our center between January 2000 and July 2011 were reviewed. Twenty-three patients met the inclusion criteria. All patients underwent successful valvuloplasty with no procedural deaths and one major complication. Excluding two patients with limited follow-up, 6 (29 %) patients underwent no subsequent interventions, whereas 9 (42 %) patients underwent surgical right-ventricular outflow tract augmentation. All except one patient with adequate follow-up have a biventricular circulation with saturation >92 %. Patients who did not undergo any right-ventricular outflow tract intervention after valvuloplasty had a significantly lower gradient across the pulmonary valve after valvuloplasty (9.9 mmHg ± 8.4 vs. 19.1 mmHg ± 10.4, p = 0.05). Significantly more patients who received a supplemental source of pulmonary blood flow had a tricuspid valve z-score <-0.7 compared with patients who did not receive supplemental blood flow [2 (15 %) vs. 7 (70 %), p = 0.008]. In our cohort of patients with PA-IVS, radiofrequency perforation with valvuloplasty was an effective and safe first step in establishing a biventricular circulation. Postvalvuloplasty pulmonary valve gradient may be predictive of subsequent outflow tract intervention, and tricuspid hypoplasia may be predictive of the need for a supplemental source of pulmonary blood flow.

Abstract
In addition to the considerable surgical advances in treating congenital heart diseases, hybrid and transcatheter therapies have become a cornerstone of neonatal cardiology within the last decade. Approaches to the care of cyanotic newborns with congenital heart disease focused on manipulations of the inter-atrial septum, right ventricular outflow tract obstructions, and on the arterial duct as the source for pulmonary blood flow. Currently, fewer interventional procedures are used in newborns and small infants to treat excessive pulmonary blood flow caused by shunt lesions, but transcatheter techniques and hybrid strategies have been developed to treat newborns suffering from inadequate systemic perfusion. However, transcatheter techniques are still not available to treat failing systemic ventricles without obvious structural disorders of the myocardium or dilated cardiomyopathies in newborns and infancy, despite new surgical-interventional strategies are already developed to avoid or to delay early heart transplantation. In conclusion, material and technical improvements have enabled transcatheter techniques to replace medical-based therapies to solve structurally dependent cardiovascular diseases. However, evidence-based and long-term follow-up data are required.

Abstract
BACKGROUND Hypoplastic left heart complex (HLHC) is characterized by a mitral valve or an aortic valve annular Z score < -2, antegrade flow in the ascending aorta, ductal dependency, coarctation or aortic arch hypoplasia, and absence of significant (sub)valvar stenosis. The Z scores of the mitral and aortic valve annuli are major determinants of HLHC. Therefore, the algorithm for Z-score calculation is essential for diagnosis. However, no single universal method of calculation is in use. In the scientific literature addressing HLHC, various Z-score calculation methods have been applied. The aim of this study was to evaluate Z scores derived from two-dimensional echocardiographic dimensions in patients with HLHC. METHODS To compare the different published methods using two-dimensional echocardiographic measures for Z-score calculation, a cohort of 18 newborns diagnosed with HLHC was retrospectively evaluated. In addition, the methods to determine body surface area in newborns were evaluated. RESULTS Three Z-score calculation methods were included and compared. Using the method of Daubeney et al. to calculate Z scores in our cohort illustrated a lack of correlation beyond a Z score < 0, compared with the methods of Zilberman et al. and Pettersen et al. Z scores calculated using Zilberman et al.'s and Pettersen et al.'s methods were fairly consistent. The equations used by Pettersen et al. are based on the largest population of neonates. CONCLUSION Although the different methods for calculating Z scores for mitral and aortic valve dimensions correspond fairly well in the normal range, Z scores < -2 diverge substantially. A useful scientific comparison of published data and outcomes of patients with HLHC remains elusive. The Z-score calculation algorithms used by Pettersen et al. appear to be the most appropriate for use in an evaluation of HLHC. Because these different methods can yield different values, reporting the method as well as the Z score is essential for an accurate diagnosis. Similarly, the method used to determine body surface area should be reported.

Abstract
OBJECTIVES We report a single institute experience of transcatheter pulmonary valvotomy using the soft end of a guidewire followed or not by a systemic-pulmonary shunt in patients with pulmonary atresia with intact ventricular septum (PAIVS) or critical pulmonary stenosis (CPS). In addition, we compare patients with or without an additional source of flow to support the pulmonary circulation after successful pulmonary valvotomy. METHODS All neonates with PAIVS or CPS who underwent primary transcatheter pulmonary valvotomy between January 2004 and December 2010 were reviewed retrospectively. Some of them needed an additional source of flow to support the pulmonary circulation. We performed a comparison between those who required an additional source of pulmonary flow and those who did not. RESULTS The initial procedure was successful in 20 out of 22 patients (seven of nine with PAIVS; all of 13 with CPS), but 10 of them needed an additional source of flow to support the pulmonary circulation: nine had arterial duct stenting and one had surgical Blalock-Taussig shunt. There were no deaths or major acute complications, except for femoral artery occlusion in three patients. The bipartite right ventricular morphology, the tricuspid z-score of ≤-0.74, the tricuspid to mitral valve ratio of ≤ 0.9, and the z-score of the diastolic interventricular septal thickness ≥ 2.37 in preprocedural examination showed more tendency of needing shunt placement. CONCLUSION Transcatheter pulmonary valvotomy using the soft end of a guidewire followed or not by the arterial duct stent implantation was an effective approach in those patients. The angiographic distinction between CPS and PAIVS did not affect anything in this study including the procedural method, success, and odds for reintervention. The degree of right ventricle cavity hypoplasia provided the main restriction to forward flow after pulmonary valvotomy.
