Analysis of myocardial deformation based on pixel tracking in two dimensional echocardiographic images enables quantitative assessment of regional left ventricular function.

OBJECTIVE To evaluate whether myocardial strain and strain rate calculated from two dimensional echocardiography by automatic frame-by-frame tracking of natural acoustic markers enables objective description of regional left ventricular (LV) function. METHODS In 64 patients parasternal two dimensional echocardiographic views at the apical, mid-ventricular… (More)
