Background: Congenital Heart Disease (CHD) is the commonest group of congenital malformations and affects 7-8 per 1000 live born newborns. Nevertheless, it is estimated that more than 50% of babies with undiagnosed CHD are not detected by routine neonatal cardiac examination. Aim: To find the incidence of CHD in newborns and to determine the accuracy of pulse oximetry for detecting clinically unrecognized critical congenital heart disease (CCHD) in the newborns...

Unilateral pulmonary artery agenesis (UPAA) is a rare malformation that can present as an isolated anomaly or may be associated with certain congenital cardiac anomalies, such as tetralogy of Fallot, atrial septal defect, coarctation of aorta, right aortic arch, truncus arteriosus and pulmonary atresia. Clinical presentation is non-specific which makes the diagnosis elusive; chronic dyspnea, hemoptysis or recurrent infections are the most common manifestations. Patients may remain asymptomatic until adulthood...

BACKGROUND: There are patients born with pulmonary atresia and a ductus arteriosus or hemi-truncus to one lung and major aortopulmonary collateral arteries (MAPCAs) to the contralateral lung. The purpose of this study was to review our surgical results for this relatively rare subset of patients. METHODS: This was a retrospective review of 35 patients with ductus/hemi-truncus in association with pulmonary atresia with ventricular septal defect and MAPCAs. Our surgical algorithm is bifurcated into two strategies: 1) patients with "favorable" MAPCAs are candidates for single stage complete repair, and 2) patients with "unfavorable" MAPCAs undergo a staged approach...

The optimal treatment for transposition of the great arteries with stenosis along the pulmonary tract has always been a challenge. En bloc rotation of the truncus arteriosus has been proposed as an alternative method in this group of patients. We report a truncus turnover in a 3-month-old, 3.4 kg infant.

Objective: To investigate the feasibility and efficacy of transcatheter closure of anastomotic leakage after aortic surgery using Amplatzer Vascular Plug Ⅲ (AVP Ⅲ). Methods: A retrospective analysis was performed in 5 patients with anastomotic leakage after aortic surgery, who underwent transcatheter closure in our hospital from January to June 2017 using AVP Ⅲ. Surgeries were performed in 3 cases of Standford type A dissection, 1 case of ascending aortic aneurysm and 1 case of persistent truncus.There were 3 males,and age was (43...

OBJECTIVES: Preoperative moderate or greater truncal valve (TV) insufficiency is one of the most important factors influencing mortality in children with truncus arteriosus. We therefore sought to determine the impact of TV insufficiency and concomitant TV surgery on children who underwent truncus arteriosus repair at a single institution. METHODS: We reviewed 180 patients who underwent truncus arteriosus repair between 1979 and 2016. Preoperative echocardiography demonstrated TV insufficiency in 80 patients (mild: 33...

The purpose of the study is to analyze the impact of hybrid stage 1 palliation on right ventricular myocardial pathology in hypoplastic left heart syndrome. Sufficient amount of right ventricular biopsies could be obtained from 16 of 32 patients who underwent Norwood operation between 2007 and 2013. Histopathological findings of right ventricle in patients who underwent primary Norwood operation (primary group, n = 5), patients with aortic atresia (HS1P AA group, n = 6) or aortic stenosis (HS1P AS group, n = 5) who underwent staged Norwood palliation following hybrid stage 1 palliation were compared...

Non-allelic homologous recombination events on chromosome 22q11.2 during meiosis can result in either the deletion (22q11.2DS) or duplication (22q11.2DupS) syndrome. Although the spectrum and frequency of congenital heart disease (CHD) are known for 22q11.2DS, there is less known for 22q11.2DupS. We now evaluated cardiac phenotypes in 235 subjects with 22q11.2DupS including 102 subjects we collected and 133 subjects that were previously reported as a confirmation and found 25% have CHD, mostly affecting the cardiac outflow tract (OFT)...

OBJECTIVE: Our institution uses a valved polytetrafluoroethylene conduit as an alternative to homografts. The objective of this study was to investigate the performance of bicuspid valved polytetrafluoroethylene conduits used for right ventricular outflow tract reconstruction in children aged less than 2 years and to evaluate risk factors for earlier conduit explant. METHODS: We performed an Institutional Review Board-approved retrospective chart review of all patients aged less than 2 years who underwent surgical right ventricular outflow tract reconstruction with a bicuspid valved polytetrafluoroethylene conduit or homograft conduit from July 2004 to December 2014...

Right ventricular outflow tract (RVOT) dysfunction is a common hemodynamic challenge for adults with congenital heart disease (ACHD), including patients with repaired tetralogy of Fallot (TOF), truncus arteriosus (TA), and those who have undergone the Ross procedure for congenital aortic stenosis and the Rastelli repair for transposition of great vessels. Pulmonary valve replacement (PVR) has become one of the most common procedures performed for ACHD patients. Areas covered: Given the advances in transcatheter technology, we conducted a detailed review of the available studies addressing the indications for PVR, historical background, evolving technology, procedural aspects, and the future direction, with an emphasis on ACHD patients...

Repair of truncus arteriosus often requires early right ventricular outflow tract (RVOT) reoperation. Using a modified repair, the branch pulmonary arteries are left in situ, which may avoid earlier RVOT reoperation. We hypothesized that our modified repair for type I and II truncus arteriosus would extend the time to RVOT reoperation. Infants with truncus arteriosus were divided into 2 groups: (1) traditional technique where the branch pulmonary arteries are excised from the truncal root, or (2) modified repair where the branch pulmonary arteries are left in situ and septated from the truncal root...

Incomplete penetrance of congenital heart defects (CHDs) was observed in a mouse model. We hypothesized that the contribution of a major genetic locus modulates the manifestation of the CHDs. After genome-wide linkage mapping, fine mapping, and high-throughput targeted sequencing, a recessive frameshift mutation of the heterogeneous nuclear ribonucleoprotein A1 (Hnrnpa1) gene was confirmed (Hnrnpa1ct). Hnrnpa1 was expressed in both the first heart field (FHF) and second heart field (SHF) at the cardiac crescent stage but was only maintained in SHF progenitors after heart tube formation...

OBJECTIVE: It is suggested that folic acid and/or multivitamins, taken periconceptionally, have a role in the prevention of many congenital anomalies. The aim of this study was to determine the serum micronutrient levels in mother-infant pairs with CHD compared with those with healthy newborns and their mothers. METHODS: Serum levels of folic acid, homocysteine, zinc, vitamin A, vitamin D, and vitamin B12 were measured from 108 newborns with CHD (study group) and 103 healthy newborns (control group)...

Background: The true incidence of truncus arteriosus in underdeveloped countries is difficult to determine. This is due largely to underreporting as a result of nonavailability of technologically advanced facilities to make definitive diagnosis prenatally. There is a lack of data on the profile and outcome of patients with persistent truncus arteriosus (PTA) in Nigeria. This study aims to document the demographic characteristics, mode of presentation, indications for echocardiography, associated anomalies, average age at diagnosis, and outcome of patients with truncus arteriosus in our center...

We describe the case of a 21-year-old patient who underwent repairs for multiple lesions including aortic and pulmonary valve replacements, right ventricular outflow tract reconstruction, revision of the right pulmonary artery route, and a repair of partial anomalous pulmonary venous drainage, which was diagnosed during this fourth sternotomy. For these patients with adult CHD, it is most important to address all underlying factors as much as possible at the redo surgery.

Marfan syndrome, bicuspid aortic valve, and/or coarctation of the aorta are associated with medial abnormalities of the ascending aortic or para-coarctation aorta. Medial abnormalities in the ascending aorta are prevalent in other type of patients with a variety of CHDs such as single ventricle, persistent truncus arteriosus, transposition of the great arteries, hypoplastic left heart syndrome, and tetralogy of Fallot, encompassing a wide age range and may predispose to dilatation, aneurysm, and rapture necessitating aortic valve and root surgery...
