Abstract
The occurrence of MAPCAs (major aortopulmonary collateral arteries) with TOF (tetralogy of Fallot) and bilateral hypoplastic pulmonary arteries together is a rare condition. Patients are typically middle-aged men who usually present with acute signs of cardiac manifestations. The anomalies have survival up to the fourth decade of life and are fraught with clinical challenges. Additionally, various congenital syndromic associations, such as DiGeorge syndrome, are associated with these anomalies. We report an extremely rare case of a 41-year-old male who came with complaints of chest pain, dyspnea on exertion, and headaches. The patient had a previous history of tuberculosis and a rare combination of MAPCAs with TOF and bilateral hypoplastic pulmonary arteries, with a right-sided aortic arch with an aplastic left subclavian artery. The importance of the case comes from the need to perform surgery on a middle-aged male who was completely asymptomatic prior to this.

Abstract
Background: The anatomy of major aortopulmonary collateral arteries (MAPCAs) can be highly variable with regard to number, anatomic origin, course, and relationship to the native pulmonary arteries. Some MAPCAs travel behind the esophagus (retroesophageal) and bronchus before entering the lung parenchyma. The purpose of this paper was to review the anatomy, physiology, and surgical characteristics of retroesophageal MAPCAs. Methods: This manuscript summarizes the data from a series of three papers that have focused on the subject of retroesophageal MAPCAs from our institution over the past ten years. Results: Two-thirds of patients evaluated had a retroesophageal MAPCA identified at surgery. Retroesophageal major aortopulmonary collateral arteries (REMs) were more common with a left arch (77%) compared with a right arch (53%). Of all REMs evaluated, 83% were single supply, 13% were dual supply with an inadequate connection, and 4% were dual supply with an adequate connection. Based on these findings, 96% of retroesophageal MAPCAs were unifocalized. Follow-up catheterization was performed at a median of 17 months after surgery; 75% of unifocalized MAPCAs were widely patent, 20% were patent but stenotic, and 5% were occluded. Conclusions: The data demonstrate that retroesophageal MAPCAs are relatively common and almost always require unifocalization. At mid-term follow-up, 95% of unifocalized MAPCAs were found to be patent.

Should Prenatal Chromosomal Microarray Analysis Be Offered for Pulmonary Atresia? A Single-Center Retrospective Study in China. Genes (Basel) 2023; 14:genes14030722. [PMID: 36980994 PMCID: PMC10047995 DOI: 10.3390/genes14030722] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/06/2023] [Accepted: 03/13/2023] [Indexed: 03/18/2023] Open
Abstract
(1) Objective: To evaluate the application of chromosomal microarray analysis (CMA) in fetuses with pulmonary atresia (PA) and to explore the risk factors for predicting chromosomal imbalances and adverse perinatal outcomes. (2) Methods: This study investigated 428 cases of PA singleton pregnancies that were tested using CMA and quantitative fluorescent polymerase chain reaction (QF-PCR) as first-line genetic testing. The PA cases were divided into two groups: an isolated group and a non-isolated group. (3) Results: CMA revealed clinically relevant copy number variations (CNVs) in 9/139 (6.47%) PA fetuses, i.e., pathogenic copy number variations (pCNVs) in 8/139 (5.76%) fetuses and likely pathogenic CNVs in 1/139 (0.72%) fetuses. Stratified analysis showed that the incidence of clinically significant variants was higher in non-isolated PA fetuses than in isolated PA fetuses (12.50%, 6/48 vs. 3.30%, 3/91, p = 0.036). Regression analysis showed that a combination of other structural abnormalities at diagnosis of PA represented the principal risk factor for chromosomal imbalances (OR = 2.672). A combination of other structural abnormalities and a high maternal age increased the risk of adverse pregnancy outcomes in PA cases, including intrauterine fetal death (IUFD), termination of pregnancy (TOP), and preterm delivery. (4) Conclusions: The value of CMA for locating imbalanced genetic variations in fetuses with PA was highlighted by this study, particularly when combined with additional structural abnormalities.

EUROPEAN JOURNAL OF CARDIO-THORACIC SURGERY : OFFICIAL JOURNAL OF THE EUROPEAN ASSOCIATION FOR CARDIO-THORACIC SURGERY 2022; 63:6865033. [PMID: 36458925 DOI: 10.1093/ejcts/ezac553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 10/24/2022] [Accepted: 12/01/2022] [Indexed: 12/03/2022]
Abstract
OBJECTIVES Children with Alagille syndrome often have complex forms of congenital heart defects with the majority having peripheral pulmonary artery stenosis (PPAS) and pulmonary valve atresia (PA) or pulmonary valve stenosis. Children with Alagille syndrome also have variable amounts of liver dysfunction. The purpose of this study was to evaluate the impact of liver dysfunction on outcomes in children with Alagille syndrome undergoing congenital heart surgery. METHODS This was a retrospective review of 69 patients with Alagille syndrome who underwent congenital heart surgery at our institution. The underlying diagnoses included PPAS (n = 29), tetralogy of Fallot with PPAS (n = 14), tetralogy with PA (n = 3), PA with ventricular septal defect and major aortopulmonary collateral arteries (n = 21) and one each with D-transposition and supravalvar aortic stenosis. RESULTS The median age at surgery was 16 months (range 0-228 months). Procedures performed included PPAS repair (n = 43), tetralogy with PA repair (n = 3), unifocalization procedures (n = 21) and other (n = 2). Forty-two (61%) patients had mild or no liver dysfunction, while 26 (38%) had moderate or severe liver dysfunction. The median cardiopulmonary bypass time was 345 min (341 with liver dysfunction, 345 without liver dysfunction). There were a total of 8 operative (12%) deaths and 3 late (4%) deaths. Six operative and 2 late deaths occurred in patients with liver dysfunction (combined 30.7%) versus 2 operative and 1 late death (combined 7.1%) for patients without liver dysfunction (P < 0.05). CONCLUSIONS These results suggest that liver dysfunction has a profound impact on survival in children with Alagille syndrome undergoing congenital heart surgery.

Unifocalization with pericardial roll technique in pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries. J Card Surg 2022; 37:2642-2650. [PMID: 35661255 DOI: 10.1111/jocs.16656] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Revised: 04/04/2022] [Accepted: 04/06/2022] [Indexed: 11/29/2022]
Abstract
OBJECTIVE This study aims to compare both the pericardial roll technique with the patch augmentation technique of the unifocalization, and single-stage complete repair with the unifocalization and shunt for the repair of the ventricular septal defect, pulmonary atresia, and major aortopulmonary collateral arteries. METHODS This was a retrospective review of the 48 patients undergoing unifocalization of the ventricular septal defect, pulmonary atresia, and major aorticopulmonary collateral arteries from a single center. Our cohort had two surgical pathways, including single-stage midline unifocalization (n = 40), unifocalization after pulmonary artery rehabilitation by creating an aortopulmonary window or central shunt (n = 8). There were two surgical techniques in single-stage midline unifocalizaton, including widening of the pulmonary arteries with a patch (n = 30), and connecting pulmonary arteries with a pericardial roll (n = 10). RESULTS A total of 14 (29.2%) of 48 patients underwent single-stage complete repair, 26 patients underwent shunt palliation with unifocalization. Combined early and late mortality was seen in seven patients in those who underwent shunt palliation with unifocalization, while it was seen in one patient in those who underwent a single-stage complete repair (mortality ratio 26.8% vs. 7.1%, p = .22). There was no statistically significant difference between the pericardial roll and patch augmentation techniques in terms of pulmonary artery reintervention (p = .65). Although all pulmonary artery reinterventions were for unilateral pulmonary artery in the roll technique group, 41.7% of reinterventions were for bilateral pulmonary arteries in the pericardial augmentation group. CONCLUSION Single-stage complete repair of the ventricular septal defect, pulmonary atresia, and major aorticopulmonary collateral arteries has better results than unifocalization with a shunt. In terms of nonvaluable raw material, the use of the pericardial roll technique is a considerable alternative for unifocalization.

Abstract
Congenital heart diseases represent one of the hallmarks of 22q11.2 deletion syndrome. In particular, conotruncal heart defects are the most frequent cardiac malformations and are often associated with other specific additional cardiovascular anomalies. These findings, together with extracardiac manifestations, may affect perioperative management and influence clinical and surgical outcome. Over the past decades, advances in genetic and clinical diagnosis and surgical treatment have led to increased survival of these patients and to progressive improvements in postoperative outcome. Several studies have investigated long-term follow-up and results of cardiac surgery in this syndrome. The aim of our review is to examine the current literature data regarding cardiac outcome and surgical prognosis of patients with 22q11.2 deletion syndrome. We thoroughly evaluate the most frequent conotruncal heart defects associated with this syndrome, such as tetralogy of Fallot, pulmonary atresia with major aortopulmonary collateral arteries, aortic arch interruption, and truncus arteriosus, highlighting the impact of genetic aspects, comorbidities, and anatomical features on cardiac surgical treatment.

Abstract
Objectives Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCAs) is a relatively rare, complex, and heterogeneous congenital heart disease. As one of the effective treatments, the midline unifocalization strategy still remains complicated and challenging due to the diverse forms of MAPCAs and pulmonary arteries. The purpose of this study is to summarize our experience of a novel three-dimensional (3D) visualized operative procedure in the single-stage complete repair with unifocalization and to clarify the benefits it may bring to us. Methods We described our experience of the 3D visualized operative procedure such as 3D printing, virtual reality (VR), and mixed reality (MR) technology in patients with PA/VSD/MAPCAs who underwent a single-stage complete repair with unifocalization. The data from the patients who underwent this procedure (3D group) and those who underwent the conventional procedure (conventional group) were compared. Results The conventional and 3D groups included 11 patients from September 2011 to December 2017 and 9 from January 2018 to March 2021, respectively. The baseline characteristics such as age, body weight, preoperative saturation, the anatomy of the pulmonary arteries and MAPCAs, the Nakata index, and TNPAI had no statistical significance. All 9 patients in the 3D group were operated only through a median sternotomy, while 8 cases (72.7%) in the conventional group needed another posterolateral thoracotomy (p = 0.001). In the 3D group, the CPB time was shorter (93.2 ± 63.8 vs. 145.1 ± 68.4 min, p = 0.099), and the median pre-CPB time per MAPCAs was significantly shorter [25.7 (14.0, 46.3) vs. 65 (41.3, 75.0) min, p = 0.031]. There was no early death in the 3D group, while there were 3 in the conventional group (0 vs. 27.3%, p = 0.218). Conclusion The novel 3D visualized operative procedure may help improve the performance of the single-stage complete repair with the midline unifocalization of PA/VSD/MAPCAs and help shorten the dissecting time of the MAPCAs. It may promote the routine and successful application of this strategy in more centers.

Abstract
Pulmonary atresia with ventricular septal defect and major aortopulmonary collaterals is a complex congenital heart defect that includes a heterogeneous subgroup of patients. Variation in the sources of pulmonary blood flow contributes to the complexity of the lesion and the diversity of approaches to its management. Unifocalization and rehabilitation focus on mobilization of collateral arteries and growth of native pulmonary arteries, respectively, with the ultimate surgical goal of achieving separated systemic and pulmonary circulations with the lowest possible right ventricular pressure. Regardless of the strategy, outcomes have altered the natural history of the disease, with a complete repair rate of approximately 80% and low early and late mortality rates. Given this heterogeneity of pulmonary vasculature, a tailored approach should be adopted for each patient, using all diagnostic methods currently offered by technical developments.

Neurodevelopmental Outcomes in Tetralogy of Fallot: A Systematic Review. CHILDREN (BASEL, SWITZERLAND) 2022; 9:children9020264. [PMID: 35204984 PMCID: PMC8870281 DOI: 10.3390/children9020264] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2022] [Revised: 02/02/2022] [Accepted: 02/11/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND Tetralogy of Fallot (TOF) represents between 7 and 10% of the total cases of congenital heart defects (CHD) and is estimated to be the most common cyanotic CHD, requiring medical or surgical intervention within the first year of life. Current advances in prenatal screening and fetal echocardiography led to increased rates of prenatal diagnosis of TOF. Furthermore, improvements in initial medical care, surgical repair, and long-term care are associated with excellent long-term survival until adulthood. Consequently, issues of morbidity have come under the spotlight, specifically neurodevelopmental and psychiatric adverse outcomes, which affect the quality of life of TOF survivors. METHOD This study is a systematic review of English articles, using PUBMED and applying the following search terms, Tetralogy of Fallot, neurodevelopment, autism, cerebral palsy, attention-deficit hyperactivity disorder. Data were extracted by two authors. RESULTS Most researchers suggest that TOF survivors score lower in neurodevelopmental tests than healthy populations of the same age and are in danger of neurodevelopmental impairments. Furthermore, it is suggested that TOF adolescents show higher rates of psychiatric disorders. CONCLUSIONS The neurodevelopment of TOF survivors is not intensively studied. Existing studies in TOF survivors focus on different developmental aspects, using different evaluation methods and thus making conclusions for either one of the four aspects of neurodevelopment (executive function, cognition, and adaptive function, speech-language and motor function, or neuropsychiatric domain). The poor outcomes of these isolated studies indicate the need for future research as well as for continuous neuropsychological assessment and close monitoring of children and adolescents with TOF.

Relation Between Pulmonary Artery Pressures Measured Intraoperatively and at One-Year Catheterization After Unifocalization and Repair of Tetralogy with Major Aortopulmonary Collateral Arteries. Semin Thorac Cardiovasc Surg 2022; 34:1013-1025.

Abstract
To assess the relationships between pulmonary artery (PA) pressure and the PA:aortic systolic pressure ratio measured intraoperatively and at surveillance catheterization in patients achieving complete unifocalization and repair for tetralogy of Fallot with major aortopulmonary collateral arteries (TOF/MAPCAs). This was a single-center retrospective cohort analysis of all patients who underwent complete repair of TOF/MAPCAs from 2002-2019 and received a postoperative surveillance catheterization at our center 6-24 months after surgery. Associations between intraoperative and catheter hemodynamic data were analyzed. 163 patients were included. Median systolic PA pressure was 30 (quartiles 26, 35) and 35 (28, 42) mmHg intraoperatively and at catherization respectively; systolic aortic pressure 90 (86, 100) and 84 (76, 92); and PA:aortic pressure ratio was 0.33 (0.28, 0.40) and 0.41 (0.34, 0.49). Moderate correlation was found between the intraoperative and catheter-based hemodynamics, with the majority of systolic PA pressures within 10mmHg and PA:Ao systolic ratios within 0.1. Changes in the ratio were influenced to a similar degree by differences in PA and aortic pressures. Surgical and/or catheter reinterventions were more common in patients with both higher intraoperative PA systolic pressure and PA:aortic systolic ratios and in those with greater discrepancy between intraoperative and catheterization values. PA systolic pressure and the PA:aortic systolic pressure ratio measured immediately after repair remain useful metrics for assessing the initial operative PA reconstruction, and as indicators of longer term hemodynamics. Initially elevated and subsequently discrepant PA systolic pressure and PA:aortic systolic pressure ratios were associated with higher rates of reintervention. (Figure 7).

Abstract
Background Pulmonary atresia and ventricular septal defect (PA-VSD), with or without systemic pulmonary collateral arteries (SPCAs), represents a complex anatomic and surgical spectrum of congenital heart disease. Currently, there is limited evidence on homograft durability after complete correction, which potentially could be affected by anatomic differences in pulmonary vasculature. Methods This retrospective single-center study included all 69 consecutive PA-VSD patients (46 with SPCAs, 23 without SPCAs) operated on between 1978 and 2018. The primary interest was in homograft durability after complete repair. Longitudinal echocardiographic homograft function and right ventricular systolic pressure were analyzed with linear mixed-effects models. Results The median duration of follow-up was 20 years. Of the 46 patients with SPCAs, 37 (80.4%) underwent biventricular correction at a median age of 2.7 years (interquartile range [IQR], 1.8-6.3 years). Two patients are currently awaiting unifocalization and correction. All 23 patients without SPCAs underwent successful complete correction at a median age of 1.6 years (IQR, 1.1-3.6 years). Freedom from any reintervention after 20 years was 15%. When a homograft was used during correction, freedom from homograft replacement after 20 years was comparable in the 2 groups (P = .925), at 32 ± 11% in the SPCA group and 32 ± 13% in the non-SPCA group. Indications for homograft replacement were isolated stenosis (n = 7; 46.7%), isolated regurgitation (n = 3; 20.0%), and mixed stenosis and regurgitation (n = 5; 33.3%) in the SPCA group and isolated stenosis (n = 8; 88.9%) and stenosis and regurgitation (n = 1; 11.1%) in the non-SPCA group. Peak homograft gradient was significantly (P = .0003) higher in patients without SPCA, with a comparable rate of progression in the 2 groups. However, the prevalence of severe pulmonary regurgitation (PR) was higher in patients with SPCAs, estimated at 35% at 10 years, compared with 15% in patients without SPCAs. Conclusions Homografts used for right ventricular outflow tract reconstruction in patients with PA-VSD, either with or without SPCAs, have similar limited durability. Repeated reintervention is common, and careful follow-up with attention to severe PR is warranted.

Abstract
DiGeorge syndrome (DGS), also known as "22q11.2 deletion syndrome" (22q11DS) (MIM # 192430 # 188400), is a genetic disorder caused by hemizygous microdeletion of the long arm of chromosome 22. In the last decades, the introduction of fluorescence in situ hybridization assays, and in selected cases the use of multiplex ligation-dependent probe amplification, has allowed the detection of chromosomal microdeletions that could not be previously identified using standard karyotype analysis. The aim of this review is to address cardiovascular and systemic involvement in children with DGS, provide genotype-phenotype correlations, and discuss their medical management and therapeutic options.

Abstract
BACKGROUND Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (MAPCAs) is a relatively rare and complex form of congenital heart disease. Unifocalization of MAPCAs has been advocated by some groups for the treatment of this condition. The purpose of this study was to assess the midterm fate of unifocalized MAPCAs in a cohort of patients with retroesophageal MAPCAs. METHODS This was a retrospective review of 37 patients who underwent a unifocalization procedure. All patients in this study had 1 or more retroesophageal MAPCAs, and detailed mapping of the MAPCAs was made based on a combination of the cardiac catheterization and surgical findings. RESULTS The 37 patients had a total of 166 MAPCAs, or 4.5 MAPCAs per patient. One hundred twenty-nine (78%) MAPCAs were unifocalized, whereas 37 (22%) were ligated because they were dual supply. Median follow-up was 69 months. At follow-up cardiac catheterization, evaluation of the 129 unifocalized MAPCAs demonstrated that 123 (95%) had antegrade flow, whereas 6 were occluded. For the 123 MAPCAs with antegrade flow, 97 (80%) were widely patent, whereas 26 were stenotic. Thirteen of the 37 patients have subsequently undergone reintervention on MAPCAs that were determined to be stenotic following unifocalization. Seven of these patients had mild disease and had complete resolution with balloon (n = 5) or surgical revision (n = 2). Six patients with moderate or severe disease underwent surgical revision with confirmed resolution in 4 of 6. CONCLUSIONS The data demonstrate that the majority of unifocalized MAPCAs remain widely patent following unifocalization. However, one-quarter of unifocalized MAPCAs develop stenoses or occlusion. These results suggest the fate for most unifocalized MAPCAs is favorable but highlight the need for close vigilance.

Abstract
Recent advances in understanding the genetic causes and anatomic subtypes of cardiac defects have revealed new links between genetic etiology, pathogenetic mechanisms and cardiac phenotypes. Although the same genetic background can result in different cardiac phenotypes, and similar phenotypes can be caused by different genetic causes, researchers’ effort to identify specific genotype–phenotype correlations remains crucial. In this review, we report on recent advances in the cardiac pathogenesis of three genetic diseases: Down syndrome, del22q11.2 deletion syndrome and Ellis–Van Creveld syndrome. In these conditions, the frequent and specific association with congenital heart defects and the recent characterization of the underlying molecular events contributing to pathogenesis provide significant examples of genotype–phenotype correlations. Defining these correlations is expected to improve diagnosis and patient stratification, and it has relevant implications for patient management and potential therapeutic options.

Correlating computed tomographic angiography of pulmonary circulation with clinical course and disease burden in patients with tetralogy of Fallot and pulmonary atresia. Eur J Radiol Open 2021; 8:100363. [PMID: 34189190 PMCID: PMC8217698 DOI: 10.1016/j.ejro.2021.100363] [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: 04/30/2021] [Revised: 06/01/2021] [Accepted: 06/07/2021] [Indexed: 11/29/2022] Open
Abstract
Pulmonary circulation in patients with TOF and pulmonary atresia can be extremely complex. The type of pulmonary circulation correlates with arborization of the pulmonary artery. There is a relationship between type of pulmonary circulation and number of MAPCAs. The morphology of pulmonary circulation determines the successful corrective surgery. All patients carry risk from serial diagnostic imaging and palliative management.
Purpose To determine the type of pulmonary circulation (PC) in patients with tetralogy of Fallot (TOF) and pulmonary atresia (TOF-PA) with the use of computed tomographic angiography (CTA), and describe their clinical courses, corrective surgery and disease burden. Methods 145 patients (median age 4 years, interquartile range: IQR2-8 years) were analyzed for PC which divided into 5 CTA-types and 11 subtypes based on presence of main pulmonary trunk (MPA) and confluent pulmonary arteries (confluence-PAs), presence of ductus arteriosus or major aortopulmonary collateral arteries (MAPCAs), respectively. Pulmonary arteries (PAs) were assessed by McGoon ratio and arborization. Corrective surgery or palliative management was recorded by type of PC. Disease burden was calculated as the sum of CTA, diagnostic angiography, and palliative management. Results The most common (N = 77, 53 %) PC was the presence of MPA with confluent-PAs (type-1) which was encountered mostly in TOF patients, followed by the presence of confluent-PAs with atretic MPA (type-2) (N = 47, 32 %) which found mainly in TOF-PA. McGoon ratio in type-1 (2.44 ± 0.84) was significantly larger than type-2 (1.61 ± 0.61) (median difference 0.84, 95 %CI 0.56–1.11, p < 0.001). Almost 2/3 of patients in type-1 (71 %) and 1/3 of patients in type-2 (34 %) achieved corrective surgery. There was no significant difference in amount of disease burden among the different PC, with the median value of 3 (IQR1-4). Conclusions Types of PC allow suggestions for size and arborization of PAs and successful surgical correction with an inverse relationship with the numbers of MAPCAs. There is no significant difference in amount of disease burden among the types of PC.

Screening of 22q11.2DS Using Multiplex Ligation-Dependent Probe Amplification as an Alternative Diagnostic Method. BIOMED RESEARCH INTERNATIONAL 2021; 2020:6945730. [PMID: 33062692 PMCID: PMC7539069 DOI: 10.1155/2020/6945730] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 06/06/2020] [Indexed: 11/18/2022]
Abstract
Background The 22q11.2 deletion syndrome (22q11.2DS) is the most common form of deletion disorder in humans. Low copy repeats flanking the 22q11.2 region confers a substrate for nonallelic homologous recombination (NAHR) events leading to rearrangements which have been reported to be associated with highly variable and expansive phenotypes. The 22q11.2DS is reported as the most common genetic cause of congenital heart defects (CHDs). Methods A total of 42 patients with congenital heart defects, as confirmed by echocardiography, were recruited. Genetic molecular analysis using a fluorescence in situ hybridization (FISH) technique was conducted as part of routine 22q11.2DS screening, followed by multiplex ligation-dependent probe amplification (MLPA), which serves as a confirmatory test. Results Two of the 42 CHD cases (4.76%) indicated the presence of 22q11.2DS, and interestingly, both cases have conotruncal heart defects. In terms of concordance of techniques used, MLPA is superior since it can detect deletions within the 22q11.2 locus and outside of the typically deleted region (TDR) as well as duplications. Conclusion The incidence of 22q11.2DS among patients with CHD in the east coast of Malaysia is 0.047. MLPA is a scalable and affordable alternative molecular diagnostic method in the screening of 22q11.2DS and can be routinely applied for the diagnosis of deletion syndromes.

Abstract
Aim To study the long‐term outcome after surgery for pulmonary atresia and ventricular septal defect (PA‐VSD), and to determine association between the contribution of major aorto‐pulmonary collateral arteries (MAPCAs) to the pulmonary blood flow, comorbidity and cause of death. Methods Patients who had undergone surgery for PA‐VSD from January 1st 1994 to December 31st 2017 were studied retrospectively. Survival was cross‐checked against the Swedish National Population Register. Results Seventy patients were identified, giving an incidence of 5.3 newborns per 100 000 live births. In 41 patients (59%) the pulmonary blood flow originated from a patent ductus arteriosus (PDA), while 29 patients (41%) had contribution of the pulmonary blood flow from MAPCAs. Extracardiac disease was found in 34 patients (49%), 16 of whom had 22q11‐microdeletion syndrome (23%). Survival at follow‐up was similar in patients with and without MAPCAs (72.4% vs. 75.6%, n.s.), with a median follow‐up time of 14.3 years (3.2–41.8 years). No difference was found in mortality in patients with or without any syndrome or extracardiac disease. Conclusion Long‐term survival did not differ between those with and without MAPCAs and no difference in mortality was seen in patients with and without concomitant extracardiac disease or any kind of syndrome.

Abstract
BACKGROUND Repair of tetralogy of Fallot (TOF) with major aortopulmonary collateral arteries (MAPCAs) requires unifocalization of pulmonary circulation, intracardiac repair with the closure of the ventricular septal defect, and placement of a right ventricle (RV) to pulmonary artery (PA) conduit. The decision to perform complete repair is sometimes aided by an intraoperative flow study to estimate the total resistance of the reconstructed pulmonary circulation. METHODS We reviewed patients who underwent unifocalization and PA reconstruction for TOF/MAPCAs to evaluate acute and mid-term outcomes after repair with and without flow studies and to characterize the relationship between PA pressure during the flow study and postrepair RV pressure. RESULTS Among 579 patients who underwent unifocalization and PA reconstruction for TOF/MAPCAs, 99 (17%) had an intraoperative flow study during one (n = 91) or more (n = 8) operations to determine the suitability for a complete repair. There was a reasonably good correlation between mean PA pressure at 3 L/min/m2 during the flow study and postrepair RV pressure and RV:aortic pressure ratio. Acute and mid-term outcomes (median: 3.8 years) after complete repair in the flow study patients (n = 78) did not differ significantly from those in whom the flow study was not performed (n = 444). Furthermore, prior failed flow study was not associated with differences in outcome after subsequent intracardiac repair. CONCLUSIONS The intraoperative flow study remains a useful adjunct for determining the suitability for complete repair in a subset of patients undergoing surgery for TOF/MAPCAs, as it is reasonably accurate for estimating postoperative PA pressure and serves as a reliable guide for the feasibility of single-stage complete repair.

Abstract
BACKGROUND The anatomy of major aortopulmonary collateral arteries (MAPCAs) can be highly variable with regard to number, anatomic origin, course, and relationship to the native pulmonary arteries. Some MAPCAs travel behind the esophagus (retroesophageal) and bronchus before entering the lung parenchyma. This study compared the physiologic and surgical characteristics of retroesophageal vs anterior located MAPCAs. METHODS This was a retrospective review of 42 patients who had 1 (n = 36) or 2 (n = 6) retroesophageal MAPCAs. These MAPCAs were then characterized as (1) single supply, meaning no connection to the pulmonary arteries; (2) dual supply, but inadequate connection to the distal pulmonary vascular bed; and (3) dual supply with adequate connection. RESULTS The 42 patients presented with 187 MAPCAs, or 4.5 MAPCAs per patient. Of these, 48 MAPCAs were retroesophageal, including 40 that were single supply, 6 were dual supply with inadequate connection, and 2 had dual supply with adequate connection. On the basis of this anatomy and physiology, 96% of retroesophageal MAPCAs were unifocalized. For the 139 anterior MAPCAs, 89 were single supply, 15 were dual supply with inadequate connection, and 35 were dual supply with adequate connection; thus, 75% of anterior MAPCAs were unifocalized (P < .01 compared with retroesophageal MAPCAs). CONCLUSIONS The data demonstrate that retroesophageal MAPCAs had very different anatomy and physiology compared with anterior MAPCAs. These results suggest that nearly every retroesophageal MAPCA should be unifocalized to incorporate the lung segments supplied.

Abstract
OBJECTIVE The aim of this study was to describe the prenatal diagnosis of Major Aortopulmonary Collateral Arteries (MAPCAs), and to present a systematic ultrasound method for evaluating lung vascularity in fetuses with pulmonary atresia with ventricular septal defect (PAVSD) and agenesis of ductus arteriosus (DA). METHOD This retrospective study evaluated fetuses diagnosed with PAVSD with agenesis of DA, for the presence of the MAPCAs anomaly. Fetal pulmonary vasculature was investigated by 2D and 4D Spatio Temporal Image Correlation (STIC) technology using High Definition Color Doppler. RESULTS Over a 10 year period, six fetuses were diagnosed with MAPCAs. Prenatal diagnosis was made between 17 w 6 d and 28 w 4 d in five fetuses, with the sixth diagnosed at 37 w 6 d. All six had PAVSD with agenesis DA, four exhibited pulmonic atresia without any arterial outflow, while two fetuses presented with absent left pulmonary artery, and a miniscule right pulmonary artery. In five cases, the parents elected to terminate the pregnancy and the last, although born alive, did not survive an attempt at restorative surgery and died at the age of 5 months. Postnatal CT angiography imaging of this case revealed the subclavian origin of the MAPCAs. Chromosomal micro array analysis of the amniotic fluid revealed that five of the six fetuses were normal and one was lost to follow up. CONCLUSION MAPCAs should be investigated in cases of PAVSD with agenesis DA. A meticulous ultrasound evaluation using 2D and 4D STIC can permit the prenatal diagnosis of this anomaly and provide the parents with the opportunity for prenatal consultation.

Abstract
BACKGROUND Surgical repair of tetralogy of Fallot and major aortopulmonary collaterals (TOF/MAPCAs) involves unifocalization of MAPCAs and reconstruction of the pulmonary arterial circulation. Surgical and cardiopulmonary bypass (CPB) times are long and suture lines are extensive. Maintaining patency of the newly anastomosed vessels while achieving hemostasis is important, and assessment of transfusion practices is critical to successful outcomes. METHODS Clinical, surgical, and transfusion data in patients with TOF/MAPCAs repaired at our institution (2013-2018) were reviewed. Types and volumes of blood products used in the perioperative period, in addition to the use of antifibrinolytics and/or procoagulants (factor VIII inhibitor bypassing activity [FEIBA]; anti-inhibitor coagulant complex), were assessed. Outcome measures included days on mechanical ventilation (DOMV), postoperative intensive care unit and hospital length of stay (LoS), and incidence of thrombosis. RESULTS Perioperative transfusion data from 279 patients were analyzed. Surgical (879 ± 175 minutes vs 684 ± 257 minutes) and CPB times (376 ± 124 minutes vs 234 ± 122 minutes) were longer in patients who received FEIBA than those who did not. Although the indexed volume of packed red blood cells (128.4 ± 82.2 mL/kg) and fresh frozen plasma (64.2 ± 41.1 mL/kg) was similar in patients who did and did not receive FEIBA, the amounts of cryoprecipitate (5.5 ± 5.2 mL/kg vs 5.8 ± 4.8 mL/kg) and platelets (19.5 ± 20.7 mL/kg vs 20.8 ± 13 mL/kg) transfused were more in those who did receive FEIBA. CONCLUSION Perioperative transfusion is an important component in the overall surgical and anesthetic management of patients with TOF/MAPCAs. The intraoperative use of FEIBA was not associated with a decrease in the amount of blood products transfused, DOMV, or LoS or with an increase in thrombotic complications.

Abstract
A strict and rational approach to Fallot's tetralogy with pulmonary atresia and major aortopulmonary collateral arteries allows to achieve optimal results. Rehabilitative and unifocalization strategies do not constitute separate philosophies; instead the surgical strategy should be tailored to each individual patient. Based on our previous experience, the ability to achieve definitive intracardiac repair is the real determinant of both improved survival and adequate systolic right ventricular performance on mid-term follow-up.

Abstract
Background Due in part to the heterogeneity of the pulmonary circulation in patients with tetralogy of Fallot and major aortopulmonary collateral arteries (MAPCAs), research on this condition has focused on relatively basic anatomic characteristics. We aimed to detail pulmonary artery (PA) and MAPCA anatomy in a large group of infants, assess relationships between anatomy and early surgical outcomes, and consider systems for classifying MAPCAs. Methods and Results All infants ( <1 year of age) undergoing first cardiac surgery for tetralogy of Fallot/MAPCAs from 2001 to 2019 at Stanford University were identified. Preoperative angiograms delineating supply to all 18 pulmonary segments were reviewed for details of each MAPCA and the arborization and size of central PAs. We studied 276 patients with 1068 MAPCAs and the following PA patterns: 152 (55%) incompletely arborizing PAs, 48 (17%) normally arborizing PAs, 45 (16%) absent PAs, and 31 (11%) unilateral MAPCAs. There was extensive anatomic variability, but no difference in early outcomes according to PA arborization or the predominance of PAs or MAPCAs. Patients with low total MAPCA and/or PA cross-sectional area were less likely to undergo complete repair. Conclusions MAPCA anatomy is highly variable and essentially unique for each patient. Though each pulmonary segment can be supplied by a MAPCA, central PA, or both, all anatomic combinations are similarly conducive to a good repair. Total cross-sectional area of central PA and MAPCA material is an important driver of outcome. We elucidate a number of novel associations between anatomic features, but the extreme variability of the pulmonary circulation makes a granular tetralogy of Fallot/MAPCA classification system unrealistic.

Abstract
BACKGROUND Single-stage unifocalisation for pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCA) requires a high degree of three-dimensional (3D) anatomical imagination. A previous study has reported the application of a 3D-printed heart model with virtual reality (VR) or mixed reality (MR). However, few studies have evaluated the surgical outcomes of the 3D model with VR or MR in PA/VSD patients. METHODS Three-dimensional (3D) heart models of five selected PA/VSD patients were derived from traditional imageology of their hearts. Using VR glasses, the 3D models were also visualised in the operating room. Both the 3D-printed heart models and preoperative evaluation by VR were used in the five selected patients for surgical simulation and better anatomical understanding. Mixed reality holograms were used as perioperative assistive tools. Surgical outcomes were assessed, including in-hospital and early follow-up clinical data. RESULTS The use of these three new technologies had favourable feedback from the surgeons on intraoperative judgment. There were no in-hospital or early deaths. No reintervention was required until the last follow-up. Three (3) patients developed postoperative complications: one had right bundle branch block and ST-segment change, one had chest drainage >7 days (>40 mL/day) and one had pneumonia. CONCLUSION The preoperative application of a 3D-printed heart model with VR or MR helped in aligning the surgical field. These technologies improved the understanding of complicated cardiac anatomy and achieved acceptable surgical outcomes as guiding surgical planning.

Abstract
Objective To evaluate surgical management and results of patients with pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries (PA/VSD/MAPCAs). Methods We reviewed a consecutive series of patients with PA/VSD/MAPCAs between January 2012 and October 2018. Study patients were separated into Group A, efficient MAPCAs; Group B, hypoplastic MAPCAs; Group C, severe hypoplastic MAPCAs at all divisions; and Group D, distal stenosis at most MAPCAs divisions. Results Thirty-six patients were included in the study. Median age at operation time was 5.5 months (2-110 months), median weight was 8 kg (2.5-21 kg), and median number of MAPCAs was three (1-6). In Group A, 14 patients underwent single-stage total correction (TC); in Group B, 18 patients underwent unifocalization and central shunting; and in Group C, four patients had aortopulmonary window creation and collateral ligation. No patient was placed in Group D. Seventy percent of patients (n=25) had the TC operation. Early mortality was not seen in Group A, but the other two groups had a 13.6% mortality rate. At the follow-up, three patients had reintervention, two had new conduit replacement, and one had right ventricular outflow tract reconstruction. Conclusion Evaluating patients with PA/VSD/MAPCAs in detail and subdividing them is quite useful in determining the appropriate surgical approach. With this strategy, TC can be achieved in most patients. Single-stage TC is better than other surgical methods due to its lower mortality and reintervention rates. Care should be taken in terms of early postoperative intensive care complications and reintervention indications during follow-ups.

Abstract
Tetralogy of Fallot (ToF) with pulmonary atresia (ToF-PA) is a complex congenital heart defect at the extreme end of the spectrum of ToF, with no antegrade flow into the pulmonary arteries. Patients differ with regard to the sources of pulmonary blood flow. In the milder spectrum of disease, there are confluent branch pulmonary arteries fed by ductus arteriosus. In more severe cases, however, the ductus arteriosus is absent, and the sole source of pulmonary blood flow is via major aortopulmonary collateral arteries (MAPCAs). The variability in the origin, size, number, and clinical course of these MAPCAs adds to the complexity of these patients. Currently, the goal of management is to establish pulmonary blood flow from the right ventricle (RV) with RV pressures that are ideally less than half of the systemic pressure to allow for closure of the ventricular septal defect. In the long term, patients with ToF-PA are at higher risk for reinterventions to address pulmonary arterial or RV-pulmonary artery conduit stenosis, progressive aortic root dilation and aortic insufficiency, and late mortality than those with less severe forms of ToF.

Abstract
OBJECTIVE The study objective was to characterize and analyze outcomes in patients with tetralogy of Fallot and major aortopulmonary collateral arteries who had undergone surgery elsewhere before referral (prereferral surgery). METHODS Patients with tetralogy of Fallot and major aortopulmonary collateral arteries who underwent surgery between 2001 and 2019 at our center were reviewed. Prereferral surgery and unoperated patients were compared, as were subsets of prereferral surgery patients who had undergone different types of prior procedures. Primary outcomes included complete repair with survival to 6 months, death, and perioperative metrics. RESULTS Of 576 patients studied, 200 (35%) had undergone a wide range and number of prior operations elsewhere, including 92 who had pulmonary blood supply through a shunt and 108 who had a right ventricle pulmonary artery connection. Patients who underwent prereferral surgery with an existing right ventricle pulmonary artery connection had undergone more prereferral surgery procedures than those with a shunt and were more likely to have a right ventricle outflow tract pseudoaneurysm or pulmonary artery stent (all P < .001) at the time of referral. The cumulative incidences of complete repair and death were similar regardless of prereferral surgery status, but the cumulative incidence of complete repair with 6-month survival was higher (P = .002) and of death lower (P = .18) in patients who had prior right ventricle pulmonary artery connection compared with those who had received a prior shunt only. CONCLUSIONS Our comprehensive management strategy for tetralogy of Fallot and major aortopulmonary collateral arteries can be applied with excellent procedural results in both unoperated patients and those who have undergone multiple and varied procedures elsewhere.

Current era outcomes of pulmonary atresia with ventricular septal defect: A single center cohort in Thailand. Sci Rep 2020; 10:5165. [PMID: 32198468 PMCID: PMC7083910 DOI: 10.1038/s41598-020-61879-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 02/28/2020] [Indexed: 11/09/2022] Open
Abstract
Pulmonary atresia with ventricular septal defect (PA/VSD) is a complex cyanotic congenital heart disease with a wide-range of presentations and treatment strategies, depending on the source of pulmonary circulation, anatomy of pulmonary arteries (PAs), and major aortopulmonary collateral arteries (MAPCAs). Data about the outcomes in developing countries is scarce. We therefore conducted a retrospective study to assess survival rates and mortality risks of 90 children with PA/VSD at Siriraj Hospital, Thailand during 2005-2016. Patients with single ventricle were excluded. Survival and mortality risks were analyzed at the end of 2018. The median age of diagnosis was 0.5 (0-13.8) years. The patients' PAs were categorized into four groups: 1) PA/VSD with confluent PAs (n = 40), 2) PA/VSD with confluent PAs and MAPCAs (n = 21), 3) PA/VSD with non-confluent PAs and MAPCAs (n = 12), and 4) PA/VSD with small native PAs and MAPCAs (n = 17). Of the 88 patients who underwent operations, 32 patients had complete repair at 8.4 ± 4.6 years old. During the follow-up [median time of 5.7 years (7 days-13.6 years)], 17 patients (18.9%) died. The survival rates at 1, 5, and 10 years of age were 95%, 83.7%, and 79.6%, respectively. Significant mortality risks were the presence of associated anomalies and non-confluent PAs.

Abstract
The 22q11.2 deletion syndrome has an estimated prevalence of 1 in 4-6,000 livebirths. The phenotype varies widely; the most common features include: facial dysmorphia, hypocalcemia, palate and speech disorders, feeding and gastrointestinal disorders, immunodeficiency, recurrent infections, neurodevelopmental and psychiatric disorders, and congenital heart disease. Approximately 60-80% of patients have a cardiac malformation most commonly including a subset of conotruncal defects (tetralogy of Fallot, truncus arteriosus, interrupted aortic arch type B), conoventricular and/or atrial septal defects, and aortic arch anomalies. Cardiac patients with a 22q11.2 deletion do not generally experience higher mortality upon surgical intervention but suffer more peri-operative complications than their non-syndromic counterparts. New guidelines suggest screening for a 22q11.2 deletion in the patient with tetralogy of Fallot, truncus arteriosus, interrupted aortic arch type B, conoventricular septal defects as well as those with an isolated aortic arch anomaly. Early identification of a 22q11.2 deletion in the neonate or infant when other syndromic features may not be apparent allows for timely parental screening for reproductive counseling and anticipatory evaluation of cardiac and noncardiac features. Screening the at-risk child or adult allows for important age-specific clinical, neurodevelopmental, psychiatric, and reproductive issues to be addressed.

Abstract
Background Tetralogy of Fallot with major aortopulmonary collateral arteries is a heterogeneous form of pulmonary artery (PA) stenosis that requires multiple forms of intervention. We present a patient-specific in vitro platform capable of sustained flow that can be used to train proceduralists and surgical teams in current interventions, as well as in developing novel therapeutic approaches to treat various vascular anomalies. Our objective is to develop an in vitro model of PA stenosis based on patient data that can be used as an in vitro phantom to model cardiovascular disease and explore potential interventions. Methods and Results From patient-specific scans obtained via computer tomography or 3-dimensional (3D) rotational angiography, we generated digital 3D models of the arteries. Subsequently, in vitro models of tetralogy of Fallot with major aortopulmonary collateral arteries were first 3D printed using biocompatible resins and next bioprinted using gelatin methacrylate hydrogel to simulate neonatal vasculature or second-order branches of an older patient with tetralogy of Fallot with major aortopulmonary collateral arteries. Printed models were used to study creation of extraluminal connection between an atretic PA and a major aortopulmonary collateral artery using a catheter-based interventional method. Following the recanalization, engineered PA constructs were perfused and flow was visualized using contrast agents and x-ray angiography. Further, computational fluid dynamics modeling was used to analyze flow in the recanalized model. Conclusions New 3D-printed and computational fluid dynamics models for vascular atresia were successfully created. We demonstrated the unique capability of a printed model to develop a novel technique for establishing blood flow in atretic vessels using clinical imaging, together with 3D bioprinting-based tissue engineering techniques. Additive biomanufacturing technologies can enable fabrication of functional vascular phantoms to model PA stenosis conditions that can help develop novel clinical applications.

Abstract
OBJECTIVES To assess features and outcome in fetuses with pulmonary atresia with ventricular septal defect (PA-VSD). METHODS Fetuses with PA-VSD were prospectively enrolled and grouped on the basis of the pulmonary blood supply, including type A (only arterial duct [DA]), type B (both DA and major aortopulmonary collateral arteries [MAPCAs] present), and type C (MAPCAs only). The echocardiography features, associated chromosomal/genetic malformations, and postnatal outcome were compared among the three groups. RESULTS Fifty-five fetuses with PA-VSD were enrolled. The presence of confluent PAs varied, with the highest displaying rate in type A and lowest rate in type C (100% vs 41.1%). The intrapericardial pulmonary arteries in all groups were hypoplastic but smaller in types B and C than in type A (P < .05). Deletion of 22q11.2 and right aortic arch were more frequently observed in types B and C than in type A. At the end of the study, overall survival rates in type C were lower than those in type A (22.1% vs 77.3%). CONCLUSION There are great differences in the size of pulmonary arteries, associated genetic malformations, and perinatal outcomes among fetuses with PA-VSD. These results could be used for family counseling and surgical planning.

Abstract
Background: Pulmonary vascular supply in tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) is highly variable. Our approach to surgical management of this condition emphasizes early repair including unifocalization and reconstruction of the pulmonary circulation, incorporating all lung segments and addressing stenoses both proximal to and within the lung, in addition to ventricular septal defect closure. At our institution, we have over 15 years of experience using lung perfusion scintigraphy (LPS) to assess the distribution of pulmonary blood flow after complete unifocalization and repair. Methods: We reviewed clinical and quantitative LPS data in 310 patients who underwent complete unifocalization and repair of TOF/MAPCAs from 2003 to 2018 at our institution. Postrepair relative lung perfusion distributions were determined from LPS initially obtained at our institution within 60 days after repair and thereafter. Results: Total lung perfusion to the right and left lungs was 58.0% ± 14.2% and 42.0% ± 14.2%, respectively. Perfusion was balanced in 75% of patients and unbalanced in 25%, including 11% in whom it was extremely unbalanced. On multivariable analysis, older age at repair, surgery other than a single-stage complete unifocalization, and native anatomy consisting of unilateral pulmonary blood supply through a ductus arteriosus were associated with unbalanced perfusion. Conclusion: We present our experience using LPS as an outcome measure after surgical repair of TOF/MAPCAs. Balanced lung perfusion was present in the majority of patients who had complete repair of TOF/MAPCAs performed at our center.

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

Abstract
BACKGROUND A 22q11 chromosome deletion is common in patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals. We sought to determine whether 22q11 chromosome deletion is associated with increased postoperative morbidity after unifocalisation surgery. METHODS We included all patients with this diagnosis undergoing primary or revision unifocalisation ± ventricular septal defect closure at our institution from 2008 to 2016, and we excluded patients with unknown 22q11 status. Demographic and surgical data were collected. We compared outcomes between those with 22q11 chromosome deletion and those without using non-parametric analysis. RESULTS We included 180 patients, 41% of whom were documented to have a chromosome 22q11 deletion. Complete unifocalisation was performed in all patients, and intracardiac repair was performed with similar frequency regardless of 22q11 chromosome status. Duration of mechanical ventilation was longer in 22q11 deletion patients. This difference remained significant after adjustment for delayed sternal closure and/or intracardiac repair. Duration of ICU stay was longer in patients with 22q11 deletion, although no longer significant when adjusted for delayed sternal closure and intracardiac repair. Finally, length of hospital stay was longer in 22q11-deleted patients, but this difference was not significant on unadjusted or adjusted analysis. CONCLUSION Children with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals and 22q11 deletion are at risk for greater prolonged mechanical ventilation after unifocalisation surgery. Careful attention should be given to the co-morbidities of this population in the perioperative period to mitigate risks that may complicate the postoperative course.

Abstract
BACKGROUND Patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals are at risk for prolonged hospitalisation after unifocalisation. Feeding problems after congenital heart surgery are associated with longer hospital stay. We sought to determine the impact of baseline, intra-operative, and postoperative factors on the need for feeding tube use at the time of discharge. METHODS We included patients with the aforementioned diagnosis undergoing unifocalisation from ages 3 months to 4 years from 2010 to 2016. We excluded patients with a pre-existing feeding tube. Patients discharged with an enteric tube were included in the feeding tube group. We compared the feeding tube group with the non-feeding-tube group by univariable and multi-variable logistic regression. RESULTS Of the 56 patients studied, 41% used tube feeding. Median age and weight z-score were similar in the two groups. A chromosome 22q11 deletion was associated with the need for a feeding tube (22q11 deletion in 39% versus 15%, p=0.05). Median cardiopulmonary bypass time in the feeding tube group was longer (335 versus 244 minutes, p=0.04). Prolonged duration of mechanical ventilation was associated with feeding tube use (48 versus 3%, p=0.001). On multi-variable analysis, prolonged mechanical ventilation was associated with feeding tube use (odds ratio 10.2, 95% confidence intervals 1.6; 63.8). CONCLUSION Among patients with tetralogy of Fallot, pulmonary atresia, and major aortopulmonary collaterals who were feeding by mouth before surgery, prolonged mechanical ventilation after unifocalisation surgery was associated with feeding tube use at discharge. Anticipation of feeding problems in this population and earlier feeding tube placement may reduce hospital length of stay.

Abstract
Major aortopulmonary collateral arteries (MAPCAs) are unique vessels associated with hypoxia induced by congenital heart disease (CHD). Although MAPCAs are essential to supply blood to the lungs, their development and proliferation can induce life-threatening complications, such as rupture into the lung. Here, we describe a rare case of esophageal bleeding from MAPCAs in a CHD patient, which was successfully treated by transcatheter arterial embolization (TAE). A 16-year-old male with CHD experienced a hematemesis and melena after the Bentall procedure to treat valvular heart disease. Emergent esophagogastroduodenoscopy revealed spurting bleeding from the middle esophageal vessels; accordingly, endoscopic variceal ligation (EVL) was performed. However, he had a hematemesis again after 2 weeks of EVL. The arterial phase of dynamic computed tomography indicated that a MAPCA associated with CHD was the origin of bleeding. Hence, TAE of this MAPCA with a mixture of n-butyl-2-cyanoacrylate and ethiodized oil was performed to prevent re-bleeding. Color Doppler mode in endoscopic ultrasonography via the esophagus revealed mosaic-like signals in MAPCAs located in the esophageal wall. This finding was consistent with tortuous MAPCAs accompanied by turbulent blood flow. When clinicians encounter CHD patients with unexpected massive esophageal bleeding, bleeding related to MAPCAs should be considered.

Abstract
BACKGROUND Patients with an open ventricular septal defect (VSD) after repair of pulmonary atresia (PA), VSD, and major aortopulmonary collaterals (MAPCAs) are the most vulnerable subgroup. We analyzed the impact of concomitant versus delayed VSD closure on survival and intermediate-term right ventricular (RV) function. METHODS Between October 1996 and February 2017, 96 patients underwent a pulmonary flow study-aided repair of PA/VSD/MAPCAs. For patients who underwent either concomitant or delayed intracardiac repair, echocardiographic RV systolic function was retrospectively calculated to assess (1) RV fractional area change (RVFAC) and (2) two-dimensional RV longitudinal strain (RVLS) of the free wall of the right ventricle. QLAB cardiac analysis software version 10.3 (Philips Medical Systems, Andover, MA) was used for analysis. RESULTS A total of 64 patients underwent concomitant VSD closure at the time of unifocalization, and 16 patients underwent delayed VSD closure at a median of 2.3 years (range: 3 days to 7.4 years). At a median follow-up of 8.1 years (range: 0.1 to 19.5 years) for the concomitant repair group versus 7.4 years (range: 0.01 to 15.3 years) for the delayed repair group, no differences in RVFAC and RVLS were observed (RVFAC: 41.0% ± 6.2% versus 41.2% ± 7.6%, p = 0.91; RVLS: -18.7 ± 4.3 versus -18.9 ± 4.0, p = 0.87). CONCLUSIONS Patients (83%) with PA/VSD/MAPCAs underwent complete repair at intermediate-term follow-up with preserved RV function. Delayed VSD closure was accomplished in 50% of the patients initially deemed unsuitable for repair. Delayed VSD closure did not affect survival and did not portend impaired RV systolic function.

Abstract
Deletion of 22q11.2 (del22q11) is associated with adverse outcomes in patients with tetralogy of Fallot (TOF). We sought to investigate its contribution to perioperative outcome in patients with a severe form of TOF characterized by pulmonary atresia (PA) or severe pulmonary stenosis (PS) and major aortopulmonary collateral arteries (MAPCAS). We conducted a retrospective review of patients with TOF/MAPCAS who underwent staged surgical reconstruction between 1995 and 2006. Groups were compared according to 22q11.2 deletion status using t-tests or the Wilcoxon Rank sum test. We included 26 subjects, 24 of whom survived the initial operation. Of those, 21 subjects had known deletion status and constitute the group for this analysis [15 with no deletion present (ND) and 6 del22q11 subjects]. There was no difference with respect to occurrence of palliative procedure prior to initial operation, or to timing of closure of the ventricular septal defect (VSD). Other than higher prevalence of prematurity (50%) in the del22q11 group versus no prematurity in the ND, the groups were comparable in terms of pre-operative characteristics. The intra- and post-operative course outcomes (length of cardiopulmonary bypass, use of vasopressors, duration of intensive care and length of hospital stay, tube-feeding) were also comparable. Although the del22q11 had longer mechanical ventilation than the ND, this difference was not significant [68 h (range 4-251) vs. 45 h (range 3-1005), p = 0.81]. In this detailed comparison of a small patient cohort, 22q11.2 deletion syndrome was not associated with adverse perioperative outcomes in patients with TOF, PA, and MAPCAS when compared to those without 22q11.2 deletion syndrome. These results are relevant to prenatal and neonatal pre-operative counseling and planning.

Abstract
OBJECTIVES To determine the early, intermediate and long-term outcomes of pulmonary atresia with ventricular septal defect (PA/VSD) Types I, II and III initially palliated by a right ventricle to pulmonary artery (RVPA) connection. METHODS We performed a retrospective study from 2000 to 2014 that included 109 patients with PA/VSD who had undergone an RVPA connection (tetralogy of Fallot and PA/VSD Type IV excluded). The end-points of this strategy were adequate pulmonary artery tree post-palliation, second palliation, biventricular repair, right ventricular pressure post-biventricular repair and late reoperation. Mean follow-up was 5.4 years (1 day to 14-78 years). RESULTS Early mortality after an RVPA connection was 2.7% (3 of 109). The interstage mortality rate was 6.6% (7 of 106). Eighty-four (77%) patients had a biventricular repair and 8 patients (7%) are awaiting repair. Overall survival was 90% at 1 year and 81% at 10 years. The RVPA connection allowed significant growth of the native pulmonary artery with a Nakata index of 101 mm2/m2 before the RVPA connection and 274 mm2/m2 after (P = 0.001). Twenty-nine reinterventions for restrictive pulmonary blood flow have been done (9 before 2 months and 20 after 2 months). Of the 84 patients who had a repair, 22 patients (26%) initially had a right ventricular pressure greater than 40 mmHg. Twenty-eight patients (33%) required late reoperation. CONCLUSIONS Hospital deaths after the RVPA connection were low. The procedure allowed good growth of the native pulmonary artery. Biventricular repair was possible in a large number of cases. The late morbidity rate remains significant. Early reinterventions could be avoided by appropriate calibration. This technique appears to be suitable for any type of PA/VSD with central pulmonary arteries.

Abstract
Injury to the phrenic nerves may occur during surgery for pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA-VSD and MAPCAs). These patients may develop respiratory failure and require diaphragm plication. The purpose of this study was to evaluate the impact of phrenic nerve palsy on recovery following surgery for PA-VSD and MAPCAs. Between 2007 and 2016, approximately 500 patients underwent surgery for PA-VSD and MAPCAs at our institution. Twenty-four patients (4.8%) subsequently had evidence of new phrenic nerve palsy. Sixteen patients were undergoing their first surgical procedure, whereas 8 were undergoing reoperations. All 24 patients underwent diaphragm plication. A cohort of matched controls was identified based on identical diagnosis and procedures but did not sustain a phrenic nerve palsy. Eighteen of the 24 patients (75%) had clinical improvement following diaphragm plication as evidenced by the ability to undergo successful extubation (5 ± 2 days), transition out of the intensive care unit (32 ± 16 days), and discharge from the hospital (42 ± 19 days). In contrast, there were 6 patients (25%) who did not demonstrate a temporal improvement following diaphragm plication, as evidenced by intervals of 61 ± 38, 106 ± 45, and 108 ± 46 days, respectively (P < 0.05 for all 3 comparisons). The 6 patients who failed to improve following diaphragm plication had a significantly greater number of comorbidities compared to the 18 patients who demonstrated improvement (2.2 vs 0.6 per patient, P < 0.05). When compared with the control group, patients who improved following diaphragm plication spent an additional 22 days and patients who failed to improve an additional 90 days in the hospital. The data demonstrate a bifurcation of clinical outcome in patients undergoing diaphragm plication following surgery for PA-VSD and MAPCAs. This bifurcation appears to be linked to the presence or absence of other comorbidities.
