Key result
Hybrid Aveir AR and Micra AV2 leadless pacing enables dual-chamber support while preserving atrial longevity.
Why the study?
In patients requiring dual-chamber leadless pacing, continuous implant-to-implant communication reduces atrial battery longevity, while disabling this communication eliminates atrioventricular synchronous pacing.
Case Report (n=1)
This case report demonstrates the feasibility of a concomitant hybrid leadless pacing system (Aveir AR and Micra AV2) during infected transvenous pacemaker extraction to provide atrial pacing with atrioventricular synchronous ventricular backup while preserving atrial battery longevity.
Supports feasibility of hybrid leadless pacing in infected extraction; hypothesis-generating and requires prospective validation.
Leadless pacing is an important option for patients with device‐related infections. In those requiring dual‐chamber support, reduced atrial battery longevity due to continuous implant‐to‐implant (i2i) communication remains a concern. While recent software updates now allow for the disablement of i2i communication when clinically appropriate, this mode does not provide atrioventricular synchronous pacing. We describe a case of a hybrid leadless system combining an atrial leadless pacemaker (Aveir AR, Abbott) and a second leadless pacemaker capable of atrial mechanical‐sensed ventricular pacing (Micra AV2, Medtronic) in the setting of extraction of an infected transvenous pacemaker, providing atrial pacing with ventricular backup capability while preserving atrial device longevity.

Alston et al. (2026) conducted a case report in Infected transvenous pacemaker requiring extraction and dual-chamber pacing support (n=1). Concomitant Aveir AR and Micra AV2 hybrid leadless pacemaker system was evaluated on Atrial pacing with ventricular backup capability while preserving atrial device longevity. A hybrid Aveir AR and Micra AV2 leadless system provided atrial pacing with ventricular backup in 1 patient undergoing infected pacemaker extraction while preserving atrial battery longevity.
