Background Sepsis-induced myocardial dysfunction is associated with poor outcomes, but
traditional measurements of systolic function such as left ventricular ejection fraction (LVEF) …

Myocardial deformation imaging is a novel echocardio-graphic method for assessment of
global and regional myocardial function. As this technology has evolved, it has been applied …

Background Cardiac resynchronization therapy (CRT) in heart failure is plagued by too
many nonresponders. The aim of the present study is to evaluate whether the estimation of …

Background: Current guidelines suggest that patients with left bundle branch block (LBBB)
be treated with cardiac resynchronization therapy (CRT); however, one-third do not have a …

Abstract Background Tissue Doppler-derived left ventricular systolic velocity (mitral S') has
shown excellent correlation to left ventricular ejection fraction (LVEF) in non-critically …

Background Previous studies have demonstrated variable patterns of longitudinal septal
deformation in patients with left ventricular (LV) dysfunction and left bundle branch block …

Aims Strain delay index (SDI) allows quantification of the wasted contraction or gain of
myocardial contractility expected after cardiac resynchronization therapy (CRT). The present …

Left ventricular mechanical dyssynchrony (LVMD) refers to the nonuniformity in mechanical
contraction and relaxation timing in different ventricular segments. We aimed to determine …

Secondary mitral regurgitation (MR) has been extensively studied in heart failure due to
reduced ejection fraction. In contrast, the occurrence and the pathogenesis of secondary MR …

Aims Although dipyridamole is a widely used pharmacological stress agent, the direct effects
on myocardium are not entirely known. Diabetic cardiomyopathy can be investigated by 2D …
