Summary

Results of a first-in-man study of a novel intracardiac leadless catheter pacemaker (LCP) show its feasibility, safety, and efficacy for right ventricular (RV) pacing, reported study investigators. The prospective, nonrandomized, single-arm LEADLESS study [NCT01700244], conducted at three sites, evaluated the in vivo implantation of the LCP for the first time in 33 patients who required a permanent rate modulated ventricular-based pacemaker.
