Allan L. Klein, MD, FASE, FRCP (C), FACC, FAHA,and FESC I enjoy my spinning class. At one moment, I am climbing up a hill with maximal resistance, the flywheel is…
Background Echocardiography is a valuable noninvasive technique to estimate cardiac output (CO) from the left ventricle (LV) not only in clinical practice but also in small-animal experiments. CO is used…
Background Guidelines suggest that an abnormal blood potassium level is a relative contraindication to performing dobutamine stress echocardiography (DSE). However, this has not been previously studied. Methods We reviewed a consecutive series…
Background In severe right heart obstruction (RHO), redistribution of cardiac output to the left ventricle (LV) is well tolerated by the fetal circulation. Although the same should be true of…
Background Speckle-tracking echocardiography allows early detection of subclinical left ventricular systolic dysfunction (LVSD) in patients with rheumatoid arthritis (RA). In this prospective study, we assessed the prevalence and the prognostic…
Background Coarctation of the aorta (CoA) is difficult to diagnose by fetal echocardiogram (F-Echo), often requiring multiple F-Echos during gestation and neonatal echocardiograms (N-Echos) after birth. Furthermore, CoA is the…
Background Mitral annular calcification (MAC) is a chronic inflammatory process with similarities to atherosclerosis. It is common in elderly patients and those with renal dysfunction. Although MAC is associated with…
Background Little is known about baseline diastolic dysfunction and changes in diastolic dysfunction grade after transcatheter aortic valve replacement (TAVR) for aortic stenosis (AS) and its impact on overall outcomes….
Background Net atrioventricular compliance (Cn), a parameter for the net compliance of the left atrium and left ventricle, is known to be a useful predictor of outcomes in patients with…
