PURPOSE The genetic etiology of atrioventricular septal defect (AVSD) is unknown in 40% cases. Conventional sequencing and arrays have identified the etiology in only a minority of nonsyndromic individuals with AVSD. METHODS Whole-exome sequencing was performed in 81 unrelated probands with AVSD to identify potentially causal variants in a comprehensive(More)
BACKGROUND Stroke in association with a patent foramen ovale (PFO) may be due to paradoxical embolization via a right to left intracardiac shunt but the exact contribution of PFO to stroke or stroke recurrence in childhood remains unclear. METHODS To review the relationship of a PFO with stroke, and evaluate associated co-morbidities. An electronic(More)
BACKGROUND Hypoxia-inducible factor (HIF1A) regulates the myocardial response to hypoxia and hemodynamic load. We investigated the association of HIF1A variants with right-ventricular (RV) remodeling after tetralogy of Fallot (TOF) repair. METHODS Children with TOF were genotyped for three single-nucleotide polymorphisms in HIF1A. Genotypes were analyzed(More)
Kawasaki disease (KD) is a major cause of acquired heart disease among children and increases the risk of myocardial infarction. While the biochemical basis of the disease is unclear, the evidence suggests interplay between a microbial infection and a genetic predisposition in the development of the disease. Diagnosis of KD based on clinical observation is(More)
Hemodynamic fluctuations and thromboembolic complications are significant areas of concern during the postoperative management of patients with univentricular hearts. The objective of this study is to review the incidence and risk factors associated with thrombosis and thromboembolic complications following total cavopulmonary anastomosis, the third stage(More)
Kawasaki disease is an acute, systemic vasculitis of unknown cause affecting mainly neonates (infants) and young children. Despite treatment during the acute phase with intravenous immunoglobulin and aspirin, up to 5% of those affected will develop coronary aneurysms, predisposing them to thrombotic complications that could result in myocardial infarction(More)
BACKGROUND The healthcare burden related to congenital heart disease (CHD) is increasing with improving survival. We assessed changing trends in prenatal risk factors for CHD in the current era in a Canadian cohort. METHODS AND RESULTS CHD patients <18 years old (n=2339) and controls without structural heart disease (n=199) were prospectively enrolled in(More)
