Background Post-treadmill digital echocardiography (post-TME) is the most widely used form of exercise echocardiography, but ischemia can rapidly resolve in the postexercise period; peak upright bicycle digital echocardiography (UBE) has…
Background The aim of this study was to evaluate changes in three-dimensional (3D) speckle-tracking–derived myocardial strain during ischemia. Methods Twenty patients referred for percutaneous coronary intervention were studied (mean age,…
Background Training of nonsonographer physicians or staff members is needed to implement carotid intima-media thickness (CIMT) and plaque screening by ultrasound for the assessment of subclinical atherosclerosis. The purpose of…
Background Left atrial (LA) and left ventricular (LV) diastolic function analysis can yield new strategies to recognize early cardiac involvement and prognostic indicators in Chagas disease. Methods Patients with Chagas…
Background Fabry disease is associated with left ventricular hypertrophy (LVH) and myocardial fibrosis. The aim of this study was to evaluate left atrial (LA) size and function using tissue Doppler–derived…
Background Fabry cardiomyopathy is characterized by progressive left ventricular hypertrophy (LVH) associated with diastolic dysfunction and is the most common cause of death in Fabry disease (FD). However, LVH is…
Background Although patients with hypertrophic cardiomyopathy (HCM) have normal ejection fractions at rest, the investigators hypothesized that these patients have differentially abnormal systolic function reserves, limiting their exercise capacity compared…
Background The long-term sequelae of Kawasaki disease (KD) are based on the coronary complications. Because KD causes generalized vasculitis, with documented aneurysms in the femoral, iliac, renal, axillary, and brachial…
Background Diagnosing coarctation of the aorta (CoA) in the presence of a patent ductus arteriosus (PDA) may require observation until PDA closure. The aim of this study was to create a…
Background The echocardiographic assessment of circulatory function in sick newborn infants has the potential to improve patient care. However, measurements are prone to error and have not been sufficiently validated….
