Key result
Tricuspid valve prolapse occurred in 8.6% of patients after Micra transcatheter pacing system implantation and was associated with longer procedure times and more deployments.

What is the incidence and characteristics of tricuspid valve prolapse after Micra transcatheter pacing system implantation?
Tricuspid valve prolapse is a notable complication (8.6%) after Micra leadless pacemaker implantation, associated with chordae tendineae rupture, longer procedure times, and more device deployments.

May warrant post-implant TV surveillance; leaves open predictors, incidence, and clinical sequelae in larger cohorts.
Background: The characteristics and incidence of patients with tricuspid valve (TV) prolapse after leadless pacemaker implantation are unknown. Methods and Results: We retrospectively identified 35 of 85 patients with sufficient echocardiographic TV imaging before and after Micra transcatheter pacing system (Micra TPS) implantation. The post-procedure incidence of TV prolapse was 8.6%, and the cause of prolapse was chordae tendineae rupture. Patients with TV prolapse had significantly longer procedure times and more deployments than patients without TV prolapse. Conclusions: TV prolapse after Micra TPS implantation is not a rare complication and is accompanied by frequent deployments and prolonged procedure times.

Kawatani et al. (2023) conducted a cohort in Patients undergoing leadless pacemaker implantation (n=35). Micra transcatheter pacing system implantation was evaluated on Post-procedure incidence of tricuspid valve prolapse. Tricuspid valve prolapse occurred in 8.6% of patients after Micra transcatheter pacing system implantation and was associated with longer procedure times and more deployments.
