Micra leadless pacemaker revisions: incidence, characteristics, and outcomes from a multicentre French cohort.

ABSTRACT:

Aims

Leadless pacemakers (LLPs) offer a valuable option for selected patients requiring ventricular pacing. However, data on revision procedures-defined as any intervention on an implanted LLP to correct dysfunction or upgrade the system, with or without removal-remain scarce. This study aimed to evaluate the real-world incidence, characteristics, and outcomes of LLP revisions, with particular emphasis on the feasibility and safety of removal.

Methods and results

This multicentre retrospective study involved 46 French centres performing LLP implantations between 2015 and 2023. Among 8994 Micra LLPs implanted, 100 revision procedures (1.1%) were performed in 100 patients, including 73 Micra VR and 27 Micra AV devices, at a median follow-up of 229 (68.5-629.8) days.
