Abstract

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.
