Background Indications for prophylactic implantable cardioverter-defibrillator implantation in patients with nonischemic dilated cardiomyopathy (DCM) are based on left ventricular (LV) ejection fraction (LVEF), although LVEF has limited ability to predict…
Background Left ventricular systolic function is a key determinant of outcome after ST-segment elevation myocardial infarction (STEMI). The aim of this study was to study speckle-tracking global longitudinal strain (GLS)…
Background To evaluate hemodynamic and functional changes of the failed left ventricle by Velocity Vector Imaging (VVI) and tissue Doppler, 22 patients with cardiogenic shock supported by extracorporeal life support…
Extracorporeal support, in the form of cardiopulmonary bypass, is used frequently in the operating room for physiologic support during cardiac surgery. However, in patients with severe respiratory and/or cardiac failure,…
Background In patients with chronic aortic regurgitation (AR), systolic wall stress and volume overload affects left ventricular (LV) systolic function and remodeling. The aim of this study was to assess…
Background Changes in the peripheral vasculature occur in patients with aortic stenosis (AS). The aims of the present study were to characterize peripheral arterial waveforms and aortic pulsewave velocity (PWV)…
Background The percutaneously implanted Edwards SAPIEN valve (Edwards Lifesciences, Irvine, CA) consists of cusps mounted within a stent. The individual impact of the stent and cusps on transvalvular flow and…
Strain is “stretching” in lay language, and “deformation” in technical terms, and can be used to measure and express myocardial deformation during contraction. Strain is a dimensionless quantity and is…
It has been more than 25 years since Hegrenaes and Hatle and Currie et al revolutionized the diagnostic approach to aortic stenosis by demonstrating an excellent correlation between aortic valve systolic…
Background A recent American College of Cardiology Foundation and American Society of Echocardiography document updated previous appropriate use criteria (AUC) for echocardiography. The aim of this study was to explore…
