End-of-service program compulsory ventricular pacing by the transvenous pacemaker remaining after implantation of a leadless pacemaker

Micra (Medtronic, Minneapolis, MN) is a leadless pacemaker implanted percutaneously through a transcatheter system1,2 and is an alternative form of ventricular pacing that may avoid the complications of traditional transvenous pacing systems.3 Compared with the traditional transvenous systems, Micra reportedly reduces the incidence of major complications by approximately 63%.4 Therefore, a leadless pacemaker is preferred for older patients with comorbidities who are at significantly increased risk of transvenous pacing systems complications.
