PURPOSE To evaluate the feasibility and accuracy of magnetic resonance (MR) coronary angiography for the detection of coronary artery anomalies in infants and children by using surgical findings as a reference. MATERIALS AND METHODS The data analysis was approved by the institutional review board. One hundred children with congenital heart disease(More)
Aortic stiffness, an important predictor of cardiovascular events, may relate to aortic calcification rather than noncalcified atherosclerotic plaque. The aim of this study was to determine the relation of aortic stiffness to aortic plaque and aortic calcification in asymptomatic postmenopausal women. One hundred female twins (mean age±standard deviation(More)
PURPOSE To assess the optimal timing for coronary magnetic resonance (MR) angiography in children with congenital heart disease by using dual cardiac phase whole-heart MR imaging. MATERIALS AND METHODS The local institutional review board approved this study, and informed consent was obtained from parents or guardians. Thirty children (13 girls; overall(More)
The purpose of this study was to evaluate the presence of diffuse myocardial fibrosis in children and adolescents with hypertrophic cardiomyopathy (HCM) and to assess associations with echocardiographic and clinical parameters of disease. While a common end point in adults with HCM, it is unclear whether diffuse myocardial fibrosis occurs early in the(More)
BACKGROUND Coronary allograft vasculopathy is the leading cause of late death after heart transplantation in children. It is poorly detected by conventional angiography. Intravascular ultrasound is invasive and costly. This study shows that magnetic resonance imaging (MRI) late gadolinium enhancement (LGE) of the coronary vessel wall can detect and grade(More)
PURPOSE To evaluate the feasibility of a single breath-hold 3D cine balanced steady-state free precession (b-SSFP) sequence after gadolinium diethylenetriamine penta-acetic acid (Gd-DTPA) injection for volumetric cardiac assessment. MATERIALS AND METHODS Fifteen adult patients routinely referred for cardiac magnetic resonance imaging (MRI) underwent(More)
AIMS Exercise limitation is common post-Fontan. Hybrid X-ray and magnetic resonance imaging (XMR) catheterization allows haemodynamic assessment by means of measurement of ventricular volumes and flow in major vessels with simultaneous invasive pressures. We aim to assess haemodynamic response to stress in patients with hypoplastic left heart syndrome(More)
BACKGROUND Cytomegalovirus (CMV) infection has been implicated as a cause of posttransplantation coronary artery disease in adults. The purpose of this retrospective observational study was to evaluate the effect of CMV on outcome after heart transplantation in children. METHODS AND RESULTS Risk factors tested were recipient age, sex, and(More)
BACKGROUND Isolated left ventricular non-compaction (LVNC) is an uncommon disorder characterized by the presence of increased trabeculations and deep intertrabecular recesses. In adults, it has been found that ejection fraction (EF) decreases significantly as non-compaction severity increases. In children however, there are a few data describing the(More)
