Key result
Leadless pacemakers appear safe after prior conventional pacing with 0 periprocedural complications or infections.
Why the study?
Leadless pacemakers are increasingly used in patients after a previously implanted conventional pacing system, but efficacy and safety in this setting required evaluation.
Is leadless pacemaker implantation safe and effective in patients with a prior conventional pacing system compared to de novo implantation?
Cohort (n=257)
Yes
Is leadless pacemaker implantation safe and effective in patients with a prior conventional pacing system compared to de novo implantation?
Leadless pacemaker implantation is safe and effective in patients with a prior conventional pacing system, with no increased risk of complications compared to de novo implantation.

Supports leadless upgrades after conventional systems in select patients; hypothesis-generating and should not yet change practice.
Jelisejevas et al. (2023) conducted a cohort in Patients requiring leadless pacemaker implantation (n=257). Leadless pacemaker implantation in patients with a prior conventional pacing system vs. Leadless pacemaker implantation without a history of conventional pacing system was evaluated on Efficacy and safety (electrical device parameters and periprocedural complications). Leadless pacemaker implantation in patients with a prior conventional pacing system was effective and safe, with 0 periprocedural complications or infections observed in this group.
