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…
Background Three-dimensional (3D) color Doppler echocardiography (CDE) provides directly measured vena contracta area (VCA). However, a large comprehensive 3D color Doppler echocardiographic study with sufficiently severe tricuspid regurgitation (TR) to…
Background Regional and global function can be measured by echocardiography using speckle-tracking, a technique that has previously been validated against crystal sonomicrometry. However, the application of Velocity Vector Imaging (VVI)…
Background Mitral annular calcification (MAC) is common in chronic kidney disease. It is associated with cardiovascular events and can cause valvular dysfunction, but it has not been systematically characterized. The…
Background The aim of this study was to explore the contribution of left ventricular (LV) basal rotation to the mechanism of chronic ischemic mitral regurgitation (MR). Methods Fifty-seven patients (52…
In the article “In Patients with Post-Infarction Left Ventricular Dysfunction, How Does Impaired Basal Rotation Affect Chronic Ischemic Mitral Regurgitation?” by Zito et al. , J Am Soc Echocardiogr 2013;26:1118-29, the…
Ischemic mitral regurgitation (MR) is a common complication of myocardial infarction thought to result from leaflet tethering caused by displacement of the papillary muscles that occurs as the left ventricle…
