Safety and Efficacy of Leadless Pacemakers: A New Era of Pacing.

Leadless pacemakers are evolving as a new technologic alternative to conventional transvenous pacemakers, though potential short-term and long-term complications have been recognized. The two currently available right ventricular leadless pacing systems are the Nanostim™ Leadless Cardiac Pacemaker (Abbott Laboratories, Chicago, IL, USA) and the Micra™ Transcatheter Pacing System (Medtronic, Minneapolis, MN, USA). This review aims to highlight the safety and efficacy of leadless pacemakers using these two devices as exemplars.
