Abstract

A cut-off of 9.8% maximum speckle-tracking radial strain in the segment with the latest mechanical delay has been proposed as predictive for selecting the best left ventricular lead placement for positive response on cardiac resynchronization therapy (CRT). However, pacing transmural scar should be avoided, and the purpose of this study was to evaluate the ability of echocardiographic radial strain to predict the presence of scar in the left ventricle segments.
