BACKGROUND There is a need for timely transition of patients with congenital heart disease who have reached adulthood. While the American Heart Association guidelines dictate that patients with moderate or great complexity lesions be seen at least every 2 years, lapse in care is common. We sought to assess the frequency and clinical impact of lapse of(More)
OBJECTIVES We sought to assess outcomes in a series of young patients with Marfan syndrome and to define the prevalence of ventricular arrhythmias in this patient population. BACKGROUND While sudden death is a well-recognized outcome in Marfan syndrome, ventricular arrhythmias are not well described. METHODS Patients were followed with echocardiography,(More)
This statement is an updated report of the American Heart Association's previous publications on exercise in children. In this statement, exercise laboratory requirements for environment, equipment, staffing, and procedures are presented. Indications and contraindications to stress testing are discussed, as are types of testing protocols and the use of(More)
BACKGROUND Myocardial bridging may cause compression of a coronary artery, and it has been suggested that myocardial ischemia may result. The clinical significance and prognostic value of myocardial bridging of the left anterior descending coronary artery in children with hypertrophic cardiomyopathy are unknown. We sought to determine the prevalence and(More)
In 7 of 8 children with idiopathic pulmonary arterial hypertension treated with intravenous epoprostenol for >1 year, concomitant use of bosentan allowed a reduction of epoprostenol and decreased its associated side effects without deterioration of clinical and hemodynamic parameters. In 3 children with normal or near-normal pulmonary artery pressure on(More)
Clinical, angiographic, radiographic, and echocardiographic data on 46 neonates with Ebstein's anomaly presenting with cyanosis between 1954 and 1996 were reviewed to determine possible risk factors for mortality. Most patients (67%) presented at birth with 3 cases diagnosed in utero. Mean systemic oxygen saturation was 62+/-12%. An atrial septal defect >(More)
BACKGROUND Mitral valve replacement (MVR) in children has been associated with a high complication rate. We sought to assess predictors of outcomes in children undergoing MVR. METHODS A retrospective review of clinical, surgical, and echocardiographic records of patients undergoing MVR was performed. Between 1982 and 2000, 53 children underwent 76 MVR(More)
OBJECTIVES We sought to determine clinical, angiographic, and echocardiographic predictors of survival in children with isolated hypertrophic cardiomyopathy (HCM) in a large pediatric centre. BACKGROUND Sudden death is a catastrophic outcome of HCM in childhood but has been difficult to predict. Current therapies might provide for improved outcome if(More)
