Objective: Apical transverse motion (ATM) is a new parameter for assessing left ventricular (LV) dyssynchrony. Speckle-tracking radial strain analysis seems to be the best method to identify potential responders to cardiac resynchronization therapy. The aim of our study was to investigate the association between ATM and radial dyssynchrony assessed by speckle-tracking echocardiography in patients with non-ischemic dilated cardiomyopathy (NDC). Methods: We examined 35 NDC patients (mean age 49.2 +/- 28.1 years
