Pacing-induced cardiomyopathy following leadless and transvenous pacemaker implantation: A multicenter retrospective study.

ABSTRACT:

Background

Pacing-induced cardiomyopathy (PICM) has been reported among patients with transvenous pacemakers (TVP). Recent reports have suggested that the incidence may be lower among patients with leadless pacemakers (LP). We performed a multicenter retrospective study to better define these rates and to identify any potential risk factors.

Objective

To determine the rates of PICM between LP and TVP and risk factors for development of PICM in each cohort.

Methods

Patients implanted with either a Micra transcatheter LP or TVP between November 2015 and January 2022 were identified from medical records at 3 large medical centers. PICM was defined as a decrease in left ventricular ejection fraction (LVEF) from pre-implant in patients with a baseline LVEF of ≥50% with a r
