BACKGROUND Cardiac magnetic resonance imaging (MRI) and CT are available in the recent era at many pediatric cardiac centers. OBJECTIVE The aim was to provide a contemporary description of diagnostic imaging trends for definition of congenital heart disease (CHD). METHODS Echocardiography, cardiac catheterization, cardiac MRI, and cardiac CT use in(More)
Kawasaki disease (KD) is the leading cause of acquired coronary disease in children and may lead to subsequent myocardial ischemia and infarction. Because coronary computed tomographic angiography (CTA) is the most sensitive noninvasive test in patients with atherosclerosis, the aim of this study was to retrospectively evaluate coronary CTA performed in(More)
OBJECTIVES To determine outcomes following balloon aortic valvuloplasty (BAV) in aortic stenosis (AS) patients with a left ventricular ejection fraction (LVEF) <20%. BACKGROUND Severe AS patients with a LVEF <20% are excluded from United States (U.S.) transcatheter aortic valve replacement (TAVR) trials and often surgical aortic valve replacement (AVR).(More)
BACKGROUND The use of cardiac computed tomography (CT) for quantification of ventricular function is limited by relatively high radiation dose. OBJECTIVES The goal of this study was to describe the radiation exposure and image quality of 70 kVp functional cardiac CT in patients with congenital heart disease (CHD). METHODS A retrospective review of 70(More)
