Abstract
Fallot-type absent pulmonary valve is a rare and complex congenital heart disease. Repair surgery for this condition during the neonatal period has a mortality rate of over 50%. We reported a neonate with Fallot-type absent pulmonary valve and occlusion of the left main bronchus. The patient's pulmonary artery had unusual anatomy of a type that has not previously been reported. This case report outlines a successful treatment strategy for patients with complex congenital heart disease and airway occlusion during the neonatal period and the effect of these unusual anatomical conditions on postoperative outcomes.

Abstract
The 22q11.2 deletion syndrome has many complications; one of them is immunodeficiency. However, the time of onset and the degree of immunodeficiency can vary. We report a case of a preterm infant with congenital cytomegalovirus infection complicated with 22q11.2 deletion syndrome and immunological abnormalities. Ultrasonography revealed pulmonary atresia, ventricular septal defect, major aortopulmonary collateral artery, and thymic hypoplasia. His serum chemistry tests on admission revealed immunoglobulin G, A, and M levels of 1,547 mg/dL, 70 mg/dL, and 274 mg/dL, respectively. A surface antigen analysis of the peripheral lymphocytes using flow cytometry revealed the following: relatively low CD4-positive T-cell levels (18.1%; 1,767/μL), very high CD8-positive T-cell levels (58.9%; 5,751/μL), and CD4/CD8 ratio of 0.31. The level of T-cell receptor excision circles was relatively low at 17.5 copies/μL. After birth, the CD8-positive T-cell level began to gradually decrease, whereas the CD4/CD8 ratio began to increase. Thrombocytopenia, neutropenia, and skin petechiae were observed on admission. However, the condition improved. Treatment for congenital cytomegalovirus infection was not provided due to the absence of viremia. Unfortunately, the patient died suddenly on the 158th day of life, and the cause of death was unknown. To the best of our knowledge, no association between 22q11 deletion syndrome and cCMV has been described in the recent medical literature. According to the calculation, around one newborn infant who have both 22q11 deletion syndrome and cCMV infection will be born each year in Japan. Healthcare providers should pay more attention to this medical situation in the future.

Abstract
Background Patients with pulmonary atresia or critical pulmonary stenosis with intact ventricular septum (PA/IVS) and biventricular circulation may require pulmonary valve replacement (PVR). Right ventricular (RV) remodeling after PVR is well described in tetralogy of Fallot (TOF); we sought to investigate RV changes in PA/IVS using cardiac magnetic resonance imaging. Methods and Results A retrospective cohort of patients with PA/IVS who underwent PVR at Boston Children's Hospital from 1995 to 2021 with cardiac magnetic resonance imaging before and after PVR was matched 1:3 with patients with TOF by age at PVR. Median regression modeling was performed with post-PVR indexed RV end-diastolic volume as the primary outcome. A total of 20 patients with PA/IVS (cases) were matched with 60 patients with TOF (controls), with median age at PVR of 14 years. Pre-PVR indexed RV end-diastolic volume was similar between groups; cases had higher RV ejection fraction (51.4% versus 48.6%; P=0.03). Pre-PVR RV free wall and left ventricular (LV) longitudinal strain were similar, although LV midcavity circumferential strain was decreased in cases (-15.6 versus -17.1; P=0.001). At a median of 2 years after PVR, indexed RV end-diastolic volume was similarly reduced; cases continued to have higher RV ejection fraction (52.3% versus 46.9%; P=0.007) with less reduction in RV mass (Δ4.5 versus 9.6 g/m2; P=0.004). Post-PVR, RV and LV longitudinal strain remained unchanged, and LV circumferential strain was similar, although lower in cases. Conclusions Compared with patients with TOF, patients with PA/IVS demonstrate similar RV remodeling after PVR, with lower reduction in RV mass and comparatively higher RV ejection fraction. Although no differences were detected in peak systolic RV or LV strain values, further investigation of diastolic parameters is needed.

Abstract
Inflammatory myofibroblastic tumour of the heart is an exceedingly rare benign neoplasm. While benign, without prompt management its impact can be devastating. Tetralogy of Fallot with absent pulmonary valve is a rare form of CHD. We present the first documented case of inflammatory myofibroblastic tumour of the heart in the presence of tetralogy of Fallot with absent pulmonary valve.

Abstract
Left pulmonary artery (LPA) stenosis with acute angulation commonly necessitates surgical revision in the treatment of tetralogy of Fallot (TOF). We investigated the clinical characteristics of acute angulation of the LPA in patients with TOF via computed tomography (CT). Between 2011 and 2022, 160 patients were diagnosed with TOF using CT. After excluding 28 patients due to insufficient records or age, 132 patients were included in the present analysis. The patients were divided into two groups according to the presence or absence of acute angulation of the LPA: group I (TOF with an acute angle of the LPA, n = 53) and group II (TOF without an acute angle of the LPA, n = 79). We retrospectively collected clinical data from electronic medical records. T-tests were used to analyze continuous variables (i.e., age, sex, weight, right ventricular outflow tract [RVOT] pressure on echocardiography, and distance to bifurcation), and Fisher's exact and chi-square tests were used to analyze categorical data (i.e., presence of the right aortic arch, pulmonary arterial atresia/hypoplasia, atrial septal defect [ASD], patent ductus arteriosus [PDA], and pulmonary valve). The groups did not differ significantly in terms of sex, weight, presence of the right aortic arch, pulmonary arterial atresia/hypoplasia, ASD, or distance to the bifurcation. Moreover, there was no significant difference between the presence and absence of PDA (P = 0.057); however, patients in group I were significantly older (143.2 ± 97.8 days) than those in group II (91.1 ± 76.0 days, P = 0.002). Furthermore, RVOT pressure was significantly higher among patients in group I (45.1 ± 22.5 mmHg) than in group II (25.0 ± 12.4 mmHg, P < 0.001). In the current study, acute angulation of the LPA in patients with TOF, as observed on CT, was associated with older age and higher RVOT pressure on echocardiography.

Abstract
BACKGROUND The objective was to study the ductus arteriosus morphology in duct-dependent pulmonary circulation and its pattern in different ventricle morphology using CT angiography. METHOD From January 2013 to December 2015, patients aged 6 months and below with duct-dependent pulmonary circulation underwent CT angiography to delineate the ductus arteriosus origin, tortuosity, site of insertion, and pulmonary artery anatomy. The ductus arteriosus were classified into type I, IIa, IIb, and III based on its site of origin, either from descending aorta, distal arch, proximal arch, or subclavian artery, respectively. RESULTS A total of 114 patients and 116 ductus arteriosus (two had bilateral ductus arteriosus) were analysed. Type I, IIa, IIb, and III ductus arteriosus were seen in 13 (11.2 %), 71 (61.2%), 21 (18.1%), and 11 (9.5%), respectively. Tortuous ductus arteriosus was found in 38 (32.7%), which was commonly seen in single ventricular lesions. Ipsilateral and bilateral branch pulmonary artery stenosis was seen in 68 (59.6%) and 6 (5.3%) patients, respectively. The majority of patients with pulmonary atresia intact ventricular septum had type I (54.4%) and non-tortuous ductus arteriosus, while those with single and biventricular lesions had type II ductus arteriosus (84.9% and 89.7%, respectively). Type III ductus arteriosus was more common in biventricular lesions (77.8%). CONCLUSIONS Ductus arteriosus in duct-dependent pulmonary circulation has a diverse morphology with a distinct origin and tortuosity pattern in different types of ventricular morphology. CT may serve as an important tool in case selection and pre-procedural planning for ductal stenting.

Abstract
In neonatal Ebstein's anomaly of the tricuspid valve, prolonged ductal patency in patients without anatomic pulmonary valve atresia can be deleterious. Circular shunts may develop in patients with different degrees of pulmonary and tricuspid insufficiency. Closure of the arterial duct may result in haemodynamic improvement in particular scenarios. The transcatheter approach is a valuable closure alternative despite some technical difficulties in large-sized arterial ducts and low birth weight neonates. Herein, we report on two consecutive term newborns with Ebstein's anomaly and large arterial ducts in whom mechanical stimulus of the arterial duct during failed attempts of transcatheter closure led after two days to definitive closure followed by good clinical outcomes.

Abstract
BACKGROUND Residual lesions following Fallot repair are primarily pulmonary regurgitation and right ventricular outflow tract obstruction. These lesions may impact exercise tolerance, particularly because of a poor increase in left ventricular stroke volume. Pulmonary perfusion imbalance is also common, but its effect on cardiac adaptation to exercise is not known. AIM To assess the association between pulmonary perfusion asymmetry and peak indexed exercise stroke volume (pSVi) in young patients. METHODS We retrospectively studied 82 consecutive patients with Fallot repair (mean age 15.2±3.8 years) who underwent echocardiography, four-dimensional flow magnetic resonance imaging and cardiopulmonary testing with pSVi measurement by thoracic bioimpedance. Normal pulmonary flow distribution was defined as right pulmonary artery perfusion between 43 and 61%. RESULTS Normal, rightward and leftward flow distributions were found in 52 (63%), 26 (32%) and four (5%) patients, respectively. Independent predictors of pSVi were right pulmonary artery perfusion (β=0.368, 95% confidence interval [CI] 0.188 to 0.548; P=0.0003), right ventricular ejection fraction (β=0.205, 95% CI 0.026 to 0.383; P=0.049), pulmonary regurgitation fraction (β=-0.283, 95% CI -0.495 to -0.072; P=0.006) and Fallot variant with pulmonary atresia (β=-0.213, 95% CI -0.416 to -0.009; P=0.041). The pSVi prediction was similar when the categorical variable right pulmonary artery perfusion>61% was used (β=0.210, 95% CI 0.006 to 0.415; P=0.044). CONCLUSION In addition to right ventricular ejection fraction, pulmonary regurgitation fraction and Fallot variant with pulmonary atresia, right pulmonary artery perfusion is a predictor of pSVi, in that rightward imbalanced pulmonary perfusion favours greater pSVi.

Abstract
OBJECTIVE Despite decades of experience, aspects of the management of tetralogy of Fallot with pulmonary stenosis (TOF) remain controversial. Practitioners must consider newer, evolving treatment strategies with limited data to guide decision making. Therefore, the TOF Clinical Practice Standards Committee was commissioned by the American Association for Thoracic Surgery to provide a framework on this topic, focused on timing and types of interventions, management of high-risk patients, technical considerations during interventions, and best practices for assessment of outcomes of the interventions. In addition, the group was tasked with identifying pertinent research questions for future investigations. It is recognized that variability in institutional experience could influence the application of this framework to clinical practice. METHODS The TOF Clinical Practice Standards Committee is a multinational, multidisciplinary group of cardiologists and surgeons with expertise in TOF. With the assistance of a medical librarian, a citation search in PubMed, Embase, Scopus, and Web of Science was performed using key words related to TOF and its management; the search was restricted to the English language and the year 2000 or later. Articles pertaining to pulmonary atresia, absent pulmonary valve, atrioventricular septal defects, and adult patients with TOF were excluded, as well as nonprimary sources such as review articles. This yielded nearly 20,000 results, of which 163 were included. Greater consideration was given to more recent studies, larger studies, and those using comparison groups with randomization or propensity score matching. Expert consensus statements with class of recommendation and level of evidence were developed using a modified Delphi method, requiring 80% of the member votes with 75% agreement on each statement. RESULTS In asymptomatic infants, complete surgical correction between age 3 and 6 months is reasonable to reduce the length of stay, rate of adverse events, and need for a transannular patch. In the majority of symptomatic neonates, both palliation and primary complete surgical correction are useful treatment options. It is reasonable to consider those with low birth weight or prematurity, small or discontinuous pulmonary arteries, chromosomal anomalies, other congenital anomalies, or other comorbidities such as intracranial hemorrhage, sepsis, or other end-organ compromise as high-risk patients. In these high-risk patients, palliation may be preferred; and, in patients with amenable anatomy, catheter-based procedures may prove favorable over surgical palliation. CONCLUSIONS Ongoing research will provide further insight into the role of catheter-based interventions. For complete surgical correction, both transatrial and transventricular approaches are effective; however, the smallest possible ventriculotomy should be utilized. When possible, the pulmonary valve should be spared; and if unsalvageable, reconstruction can be considered. At the conclusion of the operation, adequate relief of the right ventricular outflow obstruction should be confirmed, and identification of a significant fixed anatomical obstruction should prompt further intervention. Given our current knowledge and the gaps identified, we propose several key questions to be answered by future research and potentially by a TOF registry: When to palliate or proceed with complete surgical correction, as well as the ideal type of palliation; the optimal surgical approach for complete repair for the best long-term preservation of right ventricular function; and the utility, efficacy, and durability of various pulmonary valve preservation and reconstruction techniques.

Abstract
Late detection of critical congenital heart disease (CCHD) is multifactorial and ill defined. We investigated the results of pulse oximetry screening (POS) and points in the care chain that contribute to delayed detection of CCHD. The medical records of 13 infants with delayed detection at a single pediatric cardiac center between 2013 and 2016 were identified and reviewed. Left heart obstructive lesions were the most common diagnosis (n = 8; 62%) and included coarctation of the aorta (n = 6), interrupted aortic arch with ventricular septal defect (n = 1), and critical aortic stenosis (n = 1). Tetralogy of Fallot (TOF) (n = 2), truncus arteriosus (n = 1), pulmonary atresia with ventricular septal defect (n = 1), and total anomalous pulmonary venous drainage (n = 1) made up the remainder of the conditions. Routine prenatal care was reported in most infants (10/13). Infants with late detection had either a true negative POS (10/13 infants) or no POS performed (3/13 infants). At the time of detection, 5/6 (83%) infants with coarctation had normal pulse oximetry values, whereas 6/7 (86%) infants with other CCHD developed abnormal pulse oximetry values. At diagnosis, 11/13 (85%) infants had significant signs or symptoms of clinical deterioration; only 2 infants were completely asymptomatic. Late detection of CCHD is uncommon and multifactorial. Eliminating late detection is dependent upon improving detection on screening obstetrical ultrasounds, enforcement of universal POS, and attention to the neonatal physical exam.

Abstract
Absent pulmonary valve (APV) syndrome with tricuspid atresia or tricuspid stenosis (TA/TS) is an extremely rare malformation recently reported as a variant of APV with intact ventricular septum (VS). The condition, however, has univentricular physiology and unique structural and clinical features. The purpose of this study was to update the current knowledge about this condition by describing long-term outcomes of three new cases and reviewing the available literatures. A systematic literature search was performed to collect clinical and anatomical data of APV with TA/TS. Institutional medical records were retrospectively reviewed to identify APV with TA/TS patients. In a total of 62 (59 reported and 3 new) cases, patent ductus arteriosus was present in 98% of APV patients with TA/TS. A large ventricular septal defect, dilatation of the pulmonary arteries, which is typically found in APV with tetralogy of Fallot, and respiratory distress at birth were rarely reported. Most of the recent cases were successfully managed by the Glenn or Fontan procedure. Coronary artery anomaly and ventricular arrhythmia were more frequently reported as the cause of death or severe neurological sequelae (9/16 and 3/8, respectively). Additional surgical intervention was required in the mid/long-term period in three cases due to left-ventricular outflow obstruction and in two due to aortic dilatation. The Fontan and Glenn procedures improved the survival in the last two decades. In addition to coronary artery anomaly and ventricular arrhythmia, left-ventricular outflow tract obstruction and aortic dilatation should be carefully monitored.

Abstract
OBJECTIVES The objective of this study was to assess procedural outcomes of balloon pulmonary artery (PA) angioplasty procedures after complete repair of tetralogy of Fallot with major aortopulmonary collateral arteries (TOF/MAPCAs). BACKGROUND Our approach to patients with TOF/MAPCAs emphasizes early complete unifocalization and repair. Major PA reinterventions are relatively uncommon. Balloon PA angioplasty is often used, but the effectiveness of balloon PA angioplasty in this population is unknown. METHODS The study cohort comprised patients who underwent complete unifocalization and repair of TOF/ MAPCAs at our center between 2002-2018 and underwent balloon PA angioplasty after repair. To assess immediate procedural outcomes, pre- and postintervention PA measurements were compared. RESULTS We reviewed 134 vessels that were dilated a median of 1.1 years after repair in 60 patients (median 2 PA branches per patient). Treated vessels included 15 central, 64 lobar, and 55 segmental branches. The median PA diameter at the level of stenosis increased from 1.9 mm to 3.3 mm (P<.001), and the median diameter increase was 50%. All but 6 treated vessels were enlarged. The stenosis-distal diameter ratio increased from a median of 64% to 89% (P<.001). The median central PA to aortic systolic pressure ratio was 47% before and 39% after intervention (P<.001). CONCLUSIONS Balloon PA angioplasty was acutely effective at treating most stenoses of reconstructed PA branches after repair of TOF/MAPCAs. Simple angioplasty can be a useful tool in treating isolated or modest stenoses after unifocalization/PA reconstruction surgery using our approach.

Abstract
Objective: To summarize the experience of arterial duct (AD) stenting in children with ductus-dependent hypoplastic right heart syndrome (HRHS). Methods: Seven children including 4 cases of pulmonary atresia with intact ventricular septum (PA-IVS) with HRHS and 3 cases of critical pulmonary stenosis (CPS)-IVS with HRHS underwent AD stenting in Qingdao Women and Children's Hospital between January 2012 and January 2019. During the same period, 9 patients of PA-IVS with HRHS received Blalock Taussig (B-T) shunt. Two groups of children on the operation time, hospital stay time, intensive care time and mortality were compared.T test or Mann-Whitney U test was used for comparison between the two groups. Results: There was no significant difference in the age (18 (7-100) vs. 17 (1-142) d, U=31.000, P>0.05) and weight ((3.8±1.1) vs. (3.7±1.3) kg, t=0.272, P>0.05) between the AD stenting group and the B-T group.The operation time ((108±7) vs. (160±49) min, t=-4.304), intensive care time ((3.4±1.0) vs. (6.3±4.5) d, t=-8.692) and total hospitalization time ((10.3±1.0) vs. (26.3±1.0) d, t=-7.822) in the AD stenting group were differed significantly compared with the B-T group (all P<0.05). The transcutaneous oxygen saturation improved significantly (0.723±0.125 vs. 0.926±0.005, t=-6.044, P<0.05) after AD stenting. The diameter of AD stent ranged from 3.5 to 4.0 mm, and the length of AD stent was 16-21 mm. There were no complications such as vascular injury, acute thrombus, catheter spasm and death in the AD stenting group. The mortality of children in the B-T group was 3 in 9 cases. Three cases in the AD stenting group received pulmonary valvulotomy and bilateral Glenn operation at 6, 9 and 9 months after AD stenting, respectively. Conclusions: AD stenting is a feasible, effective, safe and minimally invasive procedure for children with ductus-dependent HRHS. It can even be used as an alternative to B-T shunt.

Abstract
Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries (PA/VSD/MAPCAs) is a rare form of congenital heart disease. The midline unifocalization procedure has been developed for the treatment of PA/VSD/MAPCAs. These are complex and very lengthy procedures that require an entirely different method of perfusion. The purpose of this study was to review our perfusion modifications to support these unifocalization procedures. Sixty-four unifocalization procedures have been performed at our institution during the past 3 years. The median age was 4.1 months (range 1 month-3.5 years) and the median weight at surgery was 4.5 kg (range 3.5-19 kg). The median duration of cardiopulmonary bypass was 352 minutes (range 128-629 minutes), and the median duration of cross-clamp was 24 minutes (range 14-72 minutes). The conduct of surgery included cooling to a rectal perfusion temperature of 25° and a flow rate of 100 mL/kg/min. A pH-stat strategy and del Nido cardioplegia were used. Modifications to the cardiopulmonary bypass circuit include upsizing the oxygenator, reservoir, cannulae, vent catheter, and tubing. All circuits were modified to include the capability of performing an intraoperative flow study. This study is used to determine whether the VSD can be closed during surgery. A collateral flow study circuit is also set up for first-time operations to measure the residual collateral flow after all of the MAPCAs have been harvested. Patients who require midline unifocalization will invariably require very lengthy periods of support on cardiopulmonary bypass. We have adapted our perfusion circuitry to prepare for the demands on the bypass circuit to meet the requirements of this patient population. Our institution has developed a systematic approach for the conduct of perfusion to best serve our patients presenting with PA/VSD/MAPCAs.

Abstract
Between April 2005 and February 2019, 11 adult patients underwent redo reconstruction of the right ventricular outflow tract. The primary malformation was Fallot's tetralogy in 8, transposition of the great arteries in 2, and pulmonary atresia with intact ventricular septum in 1. Mean age at redo operation was 27.4 years. Right ventricular outflow tract was reconstructed with expanded polytetrafluoroethylene conduits with bulging sinuses and a fan-shaped valve in 9, transannular patch in 1, and right ventricular outflow patch in 1. There were no early and late deaths. One patient had residual branch pulmonary stenosis, while other 10 patients had no significant pulmonary stenosis and no significant pulmonary regurgitation. Signs and symptoms were improved in these 10 patients. Re-operation should be done before the development of right ventricular dysfunction, while it can be performed with satisfactory results in adult patients.

Abstract
Objective: Undiagnosed critical congenital heart disease (CCHD) was assessed before discharge from maternity hospital.Basic information was provided for screening CCHD in the early neonatal stage.Chi-squared test was used for comparison of categorical variables(detection rate of different types of CCHD). Method: A retrospective cohort study was conducted in neonates with CCHD who were admitted to Children's Hospital of Fudan University between 1 January 2012 and 31 December 2015. For comparing with the previously reported undiagnosed rate of CCHD at discharge, CCHD was defined as all duct dependent congenital heart disease (DDCHD) and any cyanotic CHD that required early surgery. Result: A total of 1 036 infants with CCHD were included. The prenatal detection rate of CCHD was 14.04%(122/869). As a whole, 52.51% (544/1 036) of CCHD cases were undiagnosed at discharge, and 14.09%(146/1 036)were still missed after 6-week examination. The diagnoses most likely to be unrecognized at discharge included critical coarctation of the aorta (COA) (75.00%), total anomalous pulmonary venous connection (61.54%), pulmonary atresia (PA) with ventricle septal defect (VSD) (61.45%), single ventricle (SV) (60.10%) and critical aortic stenosis (52.94%). Among newborns diagnosed prior to discharge, 54.88% (270/492) due to symptom or prenatal ultrasonographic diagnosis, 45.12% (222/492) due to abnormal findings in routine examination. Among asymptomatic CCHD cases without prenatal diagnosis, 71.02% (544/766) were undiagnosed and the most common delayed diagnosis was SV (82.78%), interrupted aortic arch (81.82%), transposition of the great arteries with intact ventricular septum (79.63%), PA/VSD (79.07%), and critical COA (78.57%). Newborns with DDC were more likely to develop symptoms within the first few days after birth, in comparison with non-DDC cases. However, their detection rates were close to each other. Conclusion: The rate of misdiagnosis of CCHD before discharge from maternity hospitals is high in China, indicates the importance of implementation of CCHD screening in Chinese maternity hospitals, so as to give timely diagnosis and proper treatment.

Abstract
We experienced a case of a patient with pulmonary atresia and intact ventricular septum (PAIVS) accompanying sinusoidal communication. PAIVS can be associated with coronary artery anomalies, including sinu- soidal communications from the right ventricle to coronary. In addition, the coronary circulation depends on the blood supply from the right ventricle. The patient was a 1-year-old boy with PAIVS (9.0 kg in weight and 74 cm in height). He had undergone balloon atrial septostomy, central shunt and Glenn procedure. Preopera- tive percutaneous oxygen saturation was 85% which decreased to 80% with agitation. He was scheduled for cheiloplasty. The goals of anesthetic management for the patient were to maintain a decrease in pulmonary vascular resistance and an increase in pulmonary blood flow to sinusoidal communications. Stable Pa0₂ was maintained by adjusting FI0₂ : 0.5, and Paco₂ : 30-35 mmHg. Hemodynamics was maintained by fluid trans- fusion, maintaining urine volume and α₁-adrenoceptor agonist We used Aesculon® for monitoring cardiac output which is a noninvasive cardiac function monitor based on impedance technology.

Abstract
OBJECTIVE The Pul-stent is a new cobalt alloys stent, specially licensed for pulmonary artery stenosis. The aim of this study was to investigate the value of the stent implantation as the treatment of postoperative pulmonary artery stenosis. METHOD Clinical practice was carried out to evaluate effectiveness, safety and maneuverability of Pul-stent in the defined clinical setting. Transthoracic echocardiography, chest roentgenography and electrocardiography were carried out as follow-up studies at 1 and 3 months after procedures. RESULT Ten patients (7 males and 3 females) received Pul-stent implantation in left or right pulmonary arteries (9 stents in left and 1 stent in right). For 9 cases transcatheter stent implantation was performed and in I case hybrid procedure. The median age was 7. 9 years (range 3. 4 - 13. 7 years). The median weight was 22. 3 kg (range 13 - 32 kg). Among them 6 cases were post surgical repair of tetralogy of Fallot, 2 cases were after Fontan procedures, 1 patient was post surgical repair of pulmonary atresia with ventricular septal defect, and 1 patient had stenosis at Glenn pathway. The pressure gradient at the stenosis decreased from (31. 6 ± 10. 2) mmHg(1 mmHg =0. 133 kPa) to (7. 3 ± 10. 3) mmHg, and the diameter of the narrowest segment increased from (4. 0 ± 2. 3) mm to (9. 6 ± 2. 7) mm, the right ventricle to aortic pressure ratio decreased from 0. 54 to 0. 36, all of these improvements were statistically significant (t = 3. 9, -9. 7, 4. 5; P =0. 008, 0. 000, 0. 004). The total procedure time ranged from 55 to 220 min (median 117 min) , and the fluoroscopy time ranged from 9 to 67 min (median 26 min). There were 2 cases of post-stenting pneumorrhagia. No stent fracture, stent malposition and other severe complications were observed. Initial follow-up of 1 and 3-months showed good results with maintenance of improved caliber of the stented vessel, and the gradient across the stenosis area measured by echocardiography was (32. 0 ± 14. 6) mmHg after 3 months. Compared with before stentifng ((40.6 ± 15. 2) mmHg) and 1 month later ((30. 6 ± 13. 6) mmHg), the difference was not statistically significant (t =2. 2,1. 76; P =0. 07, 0. 10). CONCLUSION Pul-Stent tracking and delivery was excellent, the initial experience has shown that Pul-stent implantation was effective and safe in treating post-operative branch pulmonary artery stenosis. Further follow-up study should be conducted to make sure whether those good results would be kept constant.

Abstract
The association of conotruncal heart defects with 22q11.2 chromosomal microdeletions is well established. However, it is not clear whether particular types of conotruncal malformations or additional cardiovascular anomalies are associated with microdeletions. In addition, cardiac surgery outcome in children with conotruncal defects and del22q11.2 is not well described. We prospectively enrolled 214 children with conotruncal defects: 126 with tetralogy of Fallot (TOF), 18 with pulmonary atresia-ventricular septal defect (PA-VSD), 15 with truncus arteriosus communis (TAC) type I, one with interrupted aortic arch (IAA) type B, and 54 with the transposition of great arteries, who were consecutively hospitalized at the Pediatric Cardiology Department between 2003 and 2005. 22q11.2 microdeletion was identified by fluorescence in situ hybridization. The postoperative course following cardiac surgery was compared in patients with TOF and its more severe form, PA-VSD, with/without del22q11.2 (groups A and B) and TAC with/without del22q11.2 (groups C and D). In 15 of 214 patients, 22q11.2 microdeletion was diagnosed (in 11 with TOF/PA-VSD, in three with TAC, in one with IAA type B). In patients with TOF/PA-VSD and microdeletion anatomic features that were significantly associated with 22q11.2, deletion included right aortic arch (p = 0.018), aberrant right subclavian artery (p < 0.001), and major aortopulmonary collateral arteries (p = 0.016). A complicated postoperative course was more frequent and mortality was higher in patients with conotruncal defects and with/without microdeletion. We conclude that additional cardiovascular anomalies are significantly more frequent in children with 22q11.2 microdeletion and TOF/PA-VSD. Children with conotruncal heart defects and 22q11.2 microdeletion more frequently experienced complicated postoperative course after cardiac surgery.

Abstract
OBJECTIVES Patients with tetralogy of Fallot and diminutive pulmonary arteries are at risk for suprasystemic right ventricular pressure and right ventricular failure after complete repair. We report the short-term outcome and medium-term follow-up after using a fenestrated ventricular septal defect patch as a component of staged repair in selected patients. METHODS We reviewed 47 patients with tetralogy of Fallot and diminutive pulmonary arteries whose ventricular septal defect patch was fenestrated, either electively or as a rescue technique, at a single institution between 1984 and 2001. RESULTS Early mortality was 10.6% and occurred only in patients who underwent rescue fenestration. Review of medium-term follow-up (median, 39 months) revealed 4 late deaths; an additional 4 patients experienced right ventricular failure despite fenestration. Most (7/8) of these late events occurred in patients who underwent planned fenestration. Excessive left-to-right shunt through the fenestration developed in only 2 patients. CONCLUSIONS Fenestrated patch closure of the ventricular septal defect in patients with tetralogy of Fallot and diminutive pulmonary arteries resulted in 10.6% early mortality. Used preemptively in selected patients, this technique is associated with no surgical mortality and a low incidence of excessive left-to-right shunt (4%). Early survivors remain at risk for late death and right ventricular failure despite fenestration.

Abstract
The combination of complex congenital heart disease (double outlet right ventricle with pulmonary atresia, malalignment ventriculoseptal defect, right-sided aortic arch with left ductus arteriosus) and bladder exstrophy occurred in an infant with Opitz syndrome. Neither of these defects has previously been reported in association with Opitz syndrome. These malformations, which are midline defects, further characterize this syndrome as an impairment in midline development. The spectrum of congenital heart disease and genitourinary anomalies seen in Opitz syndrome is reviewed.

Abstract
Ventriculo-coronary arterial connections are frequently observed in pulmonary atresia with intact interventricular septum. Sustained right ventricular hypertension during cardiac morphogenesis is thought to be responsible for persistence of myocardial sinusoidal-coronary artery connections. Considering an unusual observation of ventriculo-coronary arterial connections in a patient with critical pulmonary valve stenosis, we speculate that sinusoidal connections in pulmonary atresia with intact ventricular septum occur not only because it is the only exit for blood from the blind right ventricle, but also because of intrinsic altered morphogenesis of the right ventricle myocardium.

Abstract
Multi-centre databases are making an increasing contribution to medical understanding. While the statistical handling of randomized experimental studies is well documented in the medical literature, the analysis of observational studies requires the addressing of additional important issues relating to the timing of entry to the study and the effect of potential explanatory variables not introduced until after that time. A series of analyses is illustrated on a small data set. The influence of single and multiple explanatory variables on the outcome after a fixed time interval and on survival time until a specific event are examined. The analysis of the effect on survival of factors that only come into play during follow-up is then considered. The aim of each analysis, the choice of data used, the essentials of the methodology, the interpretation of the results and the limitations and underlying assumptions are discussed. It is emphasized that, in contrast to randomized studies, the basis for selection and timing of interventions in observational studies is not precisely specified so that attribution of a survival effect to an intervention must be tentative. A glossary of terms is provided.

Abstract
A rare malformation of the tricuspid valve is described in which neither valvular tissue nor papillary muscles were formed, while a tricuspid orifice was present. The case involved a cyanotic newborn female infant in whom pulmonary valvular atresia was also present.
The functional, clinical, and angiocardiographic manifestations were similar to those that may be observed either in tricuspid atresia or in pulmonary atresia with intact ventricular septum.
As far as we are aware, the literature contains only one other case which bears some similarity but is not identical to the one herein reported.

Abstract
An opportunity was presented during cardiac catheterization to study the hemodynamic function of the obstructed right ventricular chamber in a heart with tricuspid stenosis, pulmonary atresia, and an intact ventricular septum.
Cineangiocardiograms demonstrated that the anatomically stenotic tricuspid orifice was also a regurgitant orifice and it is postulated that the bidirectional flow of blood associated with the tricuspid regurgitation prevents the obstructed ventricle from becoming obliterated by stasis-thrombosis.
