Key result
LP yields no reported quantitative results for PICM incidence compared to TVP.
Why the study?
Limited data are available on the incidence of pacing-induced cardiomyopathy in patients with leadless pacemakers and how this compares to patients with transvenous pacemakers.
Does leadless pacemaker implantation reduce the incidence of pacing-induced cardiomyopathy compared to transvenous pacemakers in patients requiring permanent pacing?
Cohort
No
Does leadless pacemaker implantation reduce the incidence of pacing-induced cardiomyopathy compared to transvenous pacemakers in patients requiring permanent pacing?
This study aims to determine if leadless pacemakers have a different incidence of pacing-induced cardiomyopathy compared to traditional transvenous systems.
Absence of quantitative results in this cohort leaves open any difference in pacing-induced cardiomyopathy risk between leadless and transvenous pacemakers; prospective data needed.
Pacing-induced cardiomyopathy (PICM) is a known complication in patients with permanent pacemakers (PPMs), typically occurring in patients with high right ventricular pacing burden. The introduction of the leadless pacemaker (LP) has eliminated pocket- and lead-related complications, but limited data are available on the incidence of PICM in the population with LPs and how this incidence compares to that of patients with transvenous pacemakers (TVPs).1,2 With this retrospective analysis, we sought to report the differences in PICM from a cohort where all implantation procedures were performed within the same health care system in the modern era.

Kleiman et al. (2024) conducted a cohort in Patients with permanent pacemakers. Leadless pacemaker vs. Transvenous pacemakers was evaluated on Incidence of pacing-induced cardiomyopathy (PICM). The abstract describes a retrospective analysis comparing pacing-induced cardiomyopathy incidence between leadless and transvenous pacemakers, but reports no quantitative results.
