The Lead Episode 64: Leadless pacemakers at 5-year follow-up: the Micra Transcatheter pacing system post-approval registry.
Danesh Kella, MBBS, FHRS, Mayo Clinic is joined by Michael S. Lloyd, MD, FHRS, Emory University and Siva K. Mulpuru, MD, FHRS, Mayo Clinic to discuss how the authors utilized a post-approval registry for Micra leadless pacemakers and explored the long-term outcomes at 5 years. There were 1809 patients in the leadless pacemaker arm compared to a historical cohort of transvenous pacemakers with 2667 patients. The study found no leadless pacemaker removals due to infection. The overall complication rate at 60 months was 4.5%, and the system revision rate at 60 months was 4.9%. The major complication rate at 36 months was 4.5% in the leadless pacemaker arm, compared to an 8.5% rate observed in the transvenous arm (p <0.001). Overall, long-term outcomes with Micra leadless pacemakers demonstrated low rates of major complications and the need for system revision. 
Learning Objectives
  • To review the long-term outcomes of lead less pacemaker in the real world clinical setting
