Influence of Left Ventricular Lead Location on Outcomes in the COMPANION Study

Introduction: There are no randomized controlled trial data that evaluate mortality and hospitalization rates in cardiac resynchronization therapy (CRT) recipients based on left ventricular (LV) lead location. We analyzed the event‐driven outcomes of mortality and hospitalization as well as functional outcomes including Functional Class, Quality‐of‐Life, and 6‐minute walk distance in 1,520 patients enrolled in the COMPANION study of CRT versus optimal medical therapy.
