Relationship Between Left Ventricular Dyssynchrony and Reverse Remodeling After Cardiac Resynchronization Therapy

Cardiac resynchronization therapy (CRT) is recommended for patients with advanced chronic heart failure. The presence of left ventricular (LV) dyssynchrony before CRT is an important predictor of response to the therapy. We aimed to investigate time course of LV dyssynchrony after CRT and the relationship between LV dyssynchrony improvement and reverse remodeling (RR).
