Novel active fixation mechanism permits precise placement of a left ventricular lead: early results from a multicenter clinical study.

BACKGROUND Left ventricular (LV) lead implantation for cardiac resynchronization therapy (CRT) is associated with lead dislodgement rates ranging from 3% to 10%, and some implant approaches to prevent dislodgement may contribute to suboptimal CRT response. We report our early human experience with an LV lead with a side helix for active fixation to the… (More)
