Device longevity of a leadless pacemaker family.

ABSTRACT:

Background

Leadless ventricular pacemakers have been developed for single chamber VVIR and AV synchronous pacing applications.

Aim

To assess the device longevity impact of battery/electronics enhancements of next-generation Micra leadless pacemakers, Micra VR2 and AV2, compared to Micra VR and AV.

Methods

Real-world pacing data gathered from the Micra IDE study, Medtronic's CareLink database, and historical pacemaker patient survival data from Medtronic's Device Registry were used to project device longevity and estimate the proportion of patients requiring lifetime device replacements.

Results

Based on data from 644 patients, the median projected longevity of Micra VR was 12.3 years and Micra VR2 was 16.7 years, with 91% of patients requiring a single VR2 devi
