Late left ventricular lead displacement and treatment with a new endovenous active fixation lead.

Left ventricular (LV) lead displacement is an early complication of biventricular pacemakers and leads to loss of capture, diaphragmatic pacing, and symptomatic deterioration, requiring a revision procedure. We report a case of late LV lead displacement following a coughing fit and treatment with a lead with a new principle of active fixation.
