Leadless pacemaker: Performance and complications.

Traditional transvenous cardiac pacemakers have pitfalls due to lead- and device pocket-related complications. Leadless pacemakers were developed and introduced into clinical practice to overcome the shortcomings of traditional transvenous pacemakers. In this review, we provide a description of leadless pacemaker devices, and summarize existing data on device performance. We also describe associated complications during implantation procedure as well as during the follow-up period. Although current generation devices are limited to single-chamber pacing, future generation devices are expected to progress to multi-chamber multi-component pacing systems, and eventually to battery-less devices.
