OBJECTIVES The aim of this study was to report the results of an international multicenter experience of cardiac magnetic resonance imaging (MRI) evaluation of cardiac tumors in children, each with histology correlation or a diagnosis of tuberous sclerosis, and to determine which characteristics are predictive of tumor type. BACKGROUND Individual centers(More)
PURPOSE To evaluate the feasibility of dobutamine stress magnetic resonance (DSMR) in pediatric patients. MATERIALS AND METHODS The medical records of all DSMR studies performed on patients < or =22 years old at a single institution were retrospectively reviewed. The DSMR protocol included dobutamine doses up to 40 microg/kg/minute and atropine to attain(More)
BACKGROUND D-transposition of the great arteries (TGA) with left ventricular outflow tract obstruction (LVOTO) may be treated with arterial switch operation (ASO) with or without LVOT intervention, as well as non-ASO anatomic repairs, such as aortic translocation or Rastelli procedure. We evaluated midterm results of repair for TGA/LVOTO at our institution.(More)
Adults with bicuspid aortic valves (BAVs) are at risk for progressive aortic dilation independent of valve function. The evolution of aortic dilation in children with functionally normal BAVs has not been studied. In this study, ascending aortic diameters were assessed in a group of children with functionally normal BAVs (peak gradient < or =16 mm Hg) to(More)
We describe 5 patients who presented with musculoskeletal abnormalities in the neonatal period. All patients were initially suspected to have Larsen syndrome or Beals syndrome but were subsequently diagnosed with a TGFBR2 mutation diagnostic of Loeys-Dietz syndrome. Patients had progressive aortic enlargement, which necessitated surgical intervention for 3(More)
Background- Multiple echocardiographic parameters have been identified to predict the severity of aortic regurgitation (AR) with variable reliability. This study was performed to identify which echocardiographic parameters best predict the severity of AR in a cohort of patients with congenital heart disease, using cardiovascular MRI quantification as a(More)
Marfan's syndrome (MS) and bicuspid aortic valves (BAVs) are associated with aortic dilation. Despite their histologic similarities, the 2 diseases differ with regard to the location of maximal aortic dilation. Echocardiographic analysis of aortic dimensions was performed in children with MS, children who had aortic dilation in the setting of nonstenotic(More)
We describe the case of a 3-year-old child with neonatal Marfan syndrome complicated by mitral valve prolapse with regurgitation, marked aortic root dilatation, and ventricular tachycardia. The patient had resolution of ventricular tachycardia following surgical intervention consisting of a valve-sparing aortic root replacement and mitral valve annuloplasty.
Double-outlet right atrium is a rare congenital cardiac anomaly previously described in association with atrioventricular canal defect. Straddling tricuspid valve is another uncommon anomaly that is almost always associated with a ventricular septal defect. We report the echocardiographic features of a newborn with double-outlet right atrium associated with(More)
