300.15 Transcatheter Aortic Valve Replacement-Induced Left Ventricular Dyssynchrony: A Comparative Analysis Using Myocardial Strain and Electrocardiography

Specific strain echocardiogram and electrocardiogram (ECG) measures of mechanical and electrical ventricular dyssynchrony correlate in certain disease states. We hypothesized that strain and ECG measures of dyssynchrony would correlate in patients who develop a new left bundle branch block (LBBB) or
