Background Epirubicin is a cytotoxic drug, widely used in patients with breast cancer, but its application is limited by its cardiotoxicity. Assessment of left ventricular (LV) ejection fraction (EF) is…
Background No prior studies have investigated the association of QRS-T angle with cardiac structure and function and outcomes in heart failure with preserved ejection fraction (HFpEF). The aim of this…
Background Left ventricular (LV) ejection fraction (EF) measured by two-dimensional echocardiographic (2DE) imaging is an important correlate of survival. Real-time three-dimensional echocardiographic (3DE) imaging has addressed some of the limitations…
Background Three-dimensional (3D) speckle-tracking echocardiography (STE) is an emerging technology used to quantify left ventricular (LV) function. However, the accuracy and normal values of LV strain and twist using 3D STE…
Background Global longitudinal strain (GLS) derived from two-dimensional speckle-tracking is an emerging technology, but lack of industry standards limits its application. Prior studies support using this tool to identify subclinical…
Background The authors hypothesized that aortic root geometry is different between bicuspid and tricuspid aortic stenosis (AS) that can be assessed using real-time three-dimensional (3D) transesophageal echocardiography. The aims of…
Background MitraClip implantation reduces mitral regurgitation effectively but decreases mitral valve area, creating iatrogenic mitral stenosis. Evaluation with transesophageal echocardiography intraprocedurally is necessary to measure mitral regurgitation and mitral valve…
Background Rheumatic heart disease (RHD) remains endemic in most of the developing world. Echocardiography has proved highly sensitive for early detection of RHD, but it remains too costly for most…
Background Mitral valve (MV) prolapse (MVP) is a common disorder associated with mitral regurgitation, endocarditis, heart failure, and sudden death. Nondiagnostic morphologies have been described in the familial context and…
Background Differentiating between mitral valve (MV) prolapse (MVP) and MV billowing (MVB) on two-dimensional echocardiography is challenging. The aim of this study was to test the hypothesis that color-coded models…
