Background High-intensity focused ultrasound (HIFU) can achieve accurate and focused deep tissue ablation through an extracorporeal emission. Cardiac ablation using HIFU applied transthoracically must overcome potential interference from intervening thoracic…
Benjamin F. Byrd III, MD, FASE Since its enthusiastic adoption as a diagnostic technique, ultrasound has been proven to be safe and effective at diagnosing a wide range of ailments….
Background Invasive studies have shown that children with Fontan palliation have abnormal arterial stiffness, impedance, and hydraulic power and efficiency. The aim of this study was to assess these indexes…
Background Dynamic training schedules introduce novel challenges to medical specialty training programs that require manual dexterity. The aim of this study was to examine the effect of a 3-day, intensive…
Background Right ventricular (RV) systolic function is an important prognostic determinant of cardiopulmonary pathologies in premature infants. Measurements of dominant RV longitudinal deformation are likely to provide a sensitive measure…
Background The American Society of Echocardiography’s Committee on Pediatric Echocardiography Laboratory Productivity (C-PELP) was formed to study the organizational and productivity issues particular to academic pediatric echocardiography laboratories. After much…
Background The aim of this study was to detect normal changes in fetal two-dimensional speckle-tracking echocardiography–derived values for global and regional longitudinal left and right ventricular strain, strain rate, and…
Background The ratio of tricuspid regurgitation velocity (TRV) to the time-velocity integral of the right ventricular outflow tract (TVI RVOT ) has been studied as a reliable measure to distinguish…
Pulmonary hypertension is a challenging entity in terms of etiologic diagnosis, assessment of severity, and treatment. Pulmonary hypertension may be a primary pulmonary vascular problem (familial or idiopathic) or secondary…
Background Hypertrophic cardiomyopathy (HCM) and aortic stenosis (AS) may influence left ventricular (LV) systolic function, despite preservation of LV ejection fraction. The aim of this study was to determine the…
