We report a modified Norwood stage I procedure for tricuspid atresia, transposition of great arteries, and hypoplastic right aortic arch with complete vascular ring. In this technique, we applied dual arterial cannulation to avoid circulation arrest during neoaortic reconstruction, and also corrected the arch laterality during the Norwood stage I palliation procedure. Pulmonary flow was supplied by the Blalock-Taussig shunt. Postoperative imaging revealed the patent left neoaortic arch, and the vascular ring was relieved with a patent tracheobronchial tree...

PURPOSE: Coronary-pulmonary arterial fistulas (CPAFs) are rare coronary artery anomalies that have been described only in limited case reports. This study aims to evaluate the clinical presentation and imaging findings of CPAFs collected from 6 participating medical centers along with CPAFs reported in the literature, to discern any general trends present in CPAFs. MATERIALS AND METHODS: A total of 25 cases of CPAF diagnosed by coronary computed tomography angiography were collected across 6 participating institutions...

In current practice, children with anatomically normal hearts routinely undergo fluoroscopy-free ablations. Infants and children with congenital heart disease (CHD) represent the most difficult population to perform catheter ablation without fluoroscopy. We report two neonatal patients with CHD in whom cardiac ablations were performed without fluoroscopy. The first infant had pulmonary atresia with intact ventricular septum with refractory supraventricular tachycardia, and the second infant presented with Ebstein's anomaly of the tricuspid valve along with persistent supraventricular tachycardia...

The anatomic causes for fetal right atrial dilatation with tricuspid regurgitation include Ebstein anomaly, tricuspid dysplasia, unguarded tricuspid orifice, and Uhl anomaly. Unguarded tricuspid orifice is characterized by complete or partial agenesis of the tricuspid valvular and subvalvular structures. It is commonly associated with pulmonary atresia. Its prenatal diagnosis is usually associated with unfavorable prognosis. We present a prenatally diagnosed case of fetal unguarded tricuspid orifice with description of its diagnostic workup, along with a review of literature, to enhance the understanding of this rarely reported entity...

OBJECTIVES: To assess the natural history and outcome of fetal pulmonary stenosis [PS] detected at 14 to 16 weeks gestation. METHODS: This is a retrospective study, in the years 2004-2015, with serial follow up during pregnancy. Patients referred for complete early fetal ultrasound including all fetal systems and a fetal echocardiogram. Ninety seven percent of the women were low risk, and 3% had risk factors such as maternal type 1 diabetes mellitus, exposure to teratogenic drugs or anomalies in previous pregnancies or in other family members...

A multistage plan and multidisciplinary approach are the keys to successful repair in patients with pulmonary atresia (PA) with ventricular septal defect (VSD) and major aortopulmonary collateral arteries (MAPCAs). In this article, we present a multidisciplinary approach adopted to treat a patient with PA with VSD and MAPCAs associated with left pulmonary artery interruption.

Management of pulmonary atresia with ventricular septal defect (PA-VSD) in the neonatal period presents numerous challenges. Endovascular stenting of the ductus arteriosus or of a collateral vessel in ductal-dependent pulmonary circulation as an alternative to the Blalock-Taussig (BT) shunt has become increasingly popular in the last decades. The utilization of the reverse Szabo (anchor-wire) technique for single collateral vessel stenting in a case of PA-VSD is described.

A 30-year-old female with tricuspid valve atresia, ventricular septal defect, and atrial septal defect had a neonatal modified Blalock Taussig shunt and a Fontan-Björk operation performed at five years of age. She did well initially but progressively developed signs of systemic congestion due to severe homograft stenosis and underwent successful percutaneous implantation of a Melody(®) pulmonary valve (Medtronic, Minneapolis, MN, USA) in the "tricuspid" position.

In this study, we describe an infant case of pulmonary atresia with intact ventricular septum associated with ventriculo-coronary arterial communication for which a modified Blalock-Taussig shunt operation was performed. He experienced repeated myocardial ischaemic attacks. Further examination revealed pulmonary sequestration in the right lower lobe. He therefore underwent a bidirectional Glenn operation and coil occlusion of the feeding arteries. His myocardial ischaemic attacks subsequently improved.

BACKGROUND: We hypothesized that mean pulmonary artery pressure (PAP) detected on a pulmonary flow study may predict medium-term survival and right ventricular systolic pressure (RVSP) in patients with pulmonary atresia (PA), ventricular septal defect (VSD), and major aortopulmonary collateral arteries (MAPCAs). METHODS: Fifty patients with PA/VSD/MAPCAs underwent unifocalization between 2000 and 2013, and 40 of these patients had a pulmonary flow study since 2003...

The association of tricuspid atresia with aortopulmonary window is exceptionally rare. We report a patient with tricuspid atresia, normally related great arteries, non-restrictive ventricular septal defect, and no pulmonary stenosis (type IC) with an aortopulmonary window who underwent successful initial surgical palliation. The unique anatomical feature of this case, other than the presence of the aortopulmonary window, was the absence of pulmonary stenosis at the level of either the ventricular septal defect or the pulmonary valve...

BACKGROUND: For neonates with critical left ventricular outflow tract obstruction (LVOTO), hybrid procedures are an alternative to the Norwood stage 1 procedure. Despite perceived advantages, however, outcomes are not well defined. Therefore, we compared outcomes after stage 1 hybrid and Norwood procedures. METHODS: In a critical LVOTO inception cohort (2005-2014; 20 institutions), a total of 564 neonates underwent stage 1 palliation with the Norwood operation with a modified Blalock-Taussig shunt (NW-BT; n = 232; 41%), Norwood operation with a right ventricle-to-pulmonary artery conduit (NW-RVPA; n = 222; 39%), or a hybrid procedure (n = 110; 20%)...

BACKGROUND: Percutaneous pulmonary valve implantation (PPVI) is utilized for dysfunctional right ventricular outflow tracts (RVOT) to relieve obstruction, regurgitation, and RV dysfunction. PPVI has not been reported to induce arrhythmias. This study is the first to report the incidence of ventricular tachycardia (VT) after PPVI. METHODS: This was a retrospective study of all patients who had PPVI at a single institution. All patients were admitted after PPVI for overnight telemetry monitoring...

PURPOSE: The ideal material for pediatric pulmonary artery (PA) augmentation is autologous pericardium. However, its utility for multistaged operations is limited. In this study, we applied an in vivo tissue-engineered autologous Biotube graft to a patient with congenital heart disease for the first time. DESCRIPTION: For molds of the Biotubes, two silicone 19F drain tubes were embedded in the subcutaneous spaces of a 2-year-old girl with a diagnosis of pulmonary atresia and ventricular septal defect with major aortopulmonary collateral arteries during palliative surgical procedures...

Right atrial isomerism and pulmonary atresia combined with major aortopulmonary collateral arteries are very rare. Surgical treatment becomes more challenging when an extracardiac total anomalous pulmonary venous connection (TAPVC) requiring surgical repair neonatally is also present. We describe a successful staged Fontan operation for a neonate with a single ventricle, right atrial isomerism, pulmonary atresia with major aortopulmonary collateral arteries, a small central pulmonary artery and a supracardiac TAPVC...

PURPOSE: Recurrent trachea-esophageal fistula (recTEF) is a frequent (5%-10%) complication of congenital TEF (conTEF) and esophageal atresia (EA) repair. In addition, postoperative acquired TEF (acqTEF) can occur in addition to or even in the absence of prior conTEF in the setting of esophageal anastomotic complications. Reliable repair often proves difficult by endoluminal or standard surgical techniques. We present the results of an approach that reliably identifies the TEF and facilitates airway closure as well as repair of associated tracheal and esophageal problems...

Recent advances in surgical corrections and supportive care for congenital heart disease have resulted in increasing numbers of adult survivors who may develop hematological malignancies. Treatments including chemotherapy for such patients may cause serious hemodynamic or cardiac complications, especially in those receiving stem cell transplantation. We present a 29-year-old woman with acute lymphoblastic leukemia and congenital heart disease. She had been diagnosed with pulmonary atresia with an intact ventricular septum at birth, and the anomaly was surgically corrected according to the Fontan technique at age 9 years...
