Preservation of contractile reserve of the free wall of the left ventricle one of the main predictors for response to cardiac resynchronization therapy

Abstract

Score of the role of the contractile reserve of the left ventricular free wall in patients with ischemic and dilated cardiomyopathy was investigated for the selection of candidates for cardiac resynchronization therapy (CRT). Local reserve contractility was studied by assessing the dynamics of myocardial systolic velocity by tissue Doppler pulsed-wave at rest and at peak postural tests. Preservation of contractile reserve is the most important factor for response to СRT compared with dyssynchrony.
