BACKGROUND: Our institutional approach to tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) emphasizes unifocalization and augmentation of the reconstructed pulmonary arterial (PA) circulation and complete intracardiac repair in infancy, usually in a single procedure. This approach yields a high rate of complete repair with excellent survival and low right ventricular (RV) pressure. However, little is known about remodeling of the unifocalized and reconstructed pulmonary circulation or about reinterventions on the reconstructed PAs or the RV outflow tract conduit...

The Pediatric Cardiac Genomics Consortium (PCGC) designed the Congenital Heart Disease Genetic Network Study to provide phenotype and genotype data for a large congenital heart defects (CHDs) cohort. This article describes the PCGC cohort, overall and by major types of CHDs (e.g., conotruncal defects) and subtypes of conotrucal heart defects (e.g., tetralogy of Fallot) and left ventricular outflow tract obstructions (e.g., hypoplastic left heart syndrome). Cases with CHDs were recruited through ten sites, 2010-2014...

Background: The right ventricle (RV) is not designed to sustain high pressure leading to failure. There are no current medications to help RV contraction, so further information is required on adaption of the RV to such hypertension. Methods: The Right Ventricle in Children (RVENCH) study assessed infants with congenital heart disease undergoing cardiac surgery with hypertensive RV. Clinical and echocardiographic data were recorded, and samples of RV were taken from matched infants, analysed for proteomics and compared between pathologies and with clinical and echocardiographic outcome data...

INTRODUCTION: Adults with repaired tetralogy of Fallot (ToF) have impaired exercise capacity, vascular and cardiac autonomic function, and quality of life (QoL). Specific effects of high-intensity interval or moderate continuous exercise training on these parameters in adults with repaired ToF remain unknown. METHODS AND RESULTS: Thirty adults with repaired ToF were randomized to either high-intensity interval, moderate intensity continuous training (36 sessions, 2-3 times a week) or usual care (no supervised exercise)...

Cyanotic congenital heart disease presents an increased tendency to bleed in view of subtle coagulation defects. Airway bleeding can be particularly difficult to manage while maintaining an adequate ventilation. An isolated lung bleed with the exclusion of possible traumatic, medical and surgical causes of bleeding, should alert the attending anesthesiologist to the possibility of the collateral-related bleeding. Preoperative coil embolization remains an important initial management step in a case of tetralogy of Fallot (TOF) with major aortopulmonary collaterals...

BACKGROUND: Ventricular tachyarrhythmias (VAs) are the most common cause of death in patients with repaired Tetralogy of Fallot (TOF), but predicting those at risk remains a challenge. Electrophysiological study (EPS) has been proposed to risk stratify TOF patients. OBJECTIVE: We sought to evaluate a perioperative EPS-guided approach to risk stratify TOF patients undergoing PVR and guide concomitant cryoablation. METHODS: A prospective cohort study of TOF patients undergoing EPS at time of PVR from 2006-present was conducted at 2 centers...

The increasing survival in the adulthood of patients with congenital heart disease (CHD) has changed the epidemiology of adult CHD (ACHD) patients and has led to an increment in hospitalization rates due to heart failure (HF). ACHD patients hospitalized for HF have a five-fold higher risk of death HF than those compensated. HF occurs predominantly in patients with tetralogy of Fallot, single ventricles, and after the Mustard operation for transposition of the great arteries. Diagnostic strategies applied in acquired HF patients are usually used to evaluate ACHD patients, but sometimes this can postpone the identification of HF that can become manifest with unusual and peculiar signs or symptoms...

With improved surgical techniques and medical management for patients with congenital heart diseases, more patients are living longer and well into adulthood. This improved survival comes with a price of increased morbidity, mainly secondary to increased risk of tachyarrhythmias. One of the major arrhythmias commonly encountered in this subset of cardiac patients is AF. Similar to the general population, the risk of AF increases with advancing age, and is mainly secondary to the abnormal anatomy, abnormal pressure and volume parameters in the hearts of these patients and to the increased scarring and inflammation seen in the left atrium following multiple surgical procedures...

BACKGROUND: The right ventricular (RV) contractile reserve is a measure of the dynamic function of the RV and is a sensitive indicator of volume load. This can be measured noninvasively using the tricuspid annular plane systolic excursion (TAPSE) during exercise. We studied the RV contractile reserve of patients after tetralogy of Fallot (TOF) repair with varying degree of RV dilation and pulmonary regurgitation (PR), and compared them to a control group. METHODS: Twenty-six patients who had undergone TOF repair (mean age 29 ± 10 years) were identified and stratified into three group based on the presence and severity of RV dilation and PR...

BACKGROUND: Traditional palliation for biventricular cyanotic congenital heart lesions often involves staging with systemic-to-pulmonary arterial shunts to secure pulmonary blood flow (PBF) in the newborn period prior to complete repair. However, shunts may lead to life-threatening events secondary to shunt occlusion or acute coronary steal. They may be associated with morbidity secondary to diastolic runoff, systemic steal and volume loading, and do not provide pulsatile flow which has the potential to promote pulmonary artery (PA) growth...

Rotational angiography (RA) has proven to be an excellent method for evaluating congenital disease (CHD) in the cardiac cath lab, permitting acquisition of 3D datasets with superior spatial resolution. This technique has not been routinely implemented for 3D printing in CHD. We describe our case series of models printed from RA and validate our technique. All patients with models printed from RA were selected. RA acquisitions from a Toshiba Infinix-I system were postprocessed and printed with a Stratasys Eden 260...

OBJECTIVE: In tetralogy of Fallot (TOF), the dominant ventricular tachycardia substrates are slow-conducting anatomical isthmuses. Surgical correction has evolved, which might have influenced isthmus presence and dimensions. METHODS: One hundred and forty-two postmortem TOF specimens (84/58 corrected/uncorrected) were studied for isthmus presence. Isthmus 1 is located between the tricuspid annulus and right ventricular (RV) outflow tract (RVOT) patch/RV incision, isthmus 2 between RVOT patch/RV incision and pulmonary valve, isthmus 3 between pulmonary valve and ventricular septal defect (patch), isthmus 4 between ventricular septal defect (patch) and tricuspid annulus...

miR-138 modulates cardiac morphogenesis in zebrafish. We explored whether a genetic polymorphism in miR-138 might contribute to the occurrence of sporadic congenital heart disease (CHD) and the potential mechanism. We performed a case-control study consisting of 857 CHD cases and 938 non-CHD controls by genotyping miR-138 in a Chinese population. Two SNPs, including rare rs139365823 located in the pre-miR-138 sequence and rs76987351 located in the pri-miR-138 sequence, were identified by sequencing miR-138...
