Summary
Pacing-induced cardiomyopathy (PICM) can occur with right ventricular pacing. A dual-snare technique enables safe extraction of leadless pacemakers (Micra AV) for upgrading to left bundle branch pacing (LBBP) in these patients.
Area of Science:
- Cardiology
- Electrophysiology
- Medical Device Technology
Background:
- Pacing-induced cardiomyopathy (PICM) is a known complication of chronic high-burden right ventricular pacing (RVP).
- Left bundle branch pacing (LBBP) shows promise in managing PICM.
- Leadless pacemakers (LPs), such as the Micra AV, are increasingly used for bradyarrhythmias but may still cause PICM with RVP.
