Progressive tricuspid regurgitation and elevated pressure gradient after transvenous permanent pacemaker implantation.

ABSTRACT:

Background

The association of postimplant tricuspid regurgitation (TR) and heart failure (HF) hospitalization in patients without HF and preexisting abnormal TR and TR pressure gradient (PG) remain unclear.

Hypothesis

This study aimed to explore the clinical outcomes of progressive postimplant TR after permanent pacemaker (PPM) implantation.

Methods

A total of 1670 patients who underwent a single ventricular or dual-chamber transvenous PPM implantation at our hospital between January 2003 and December 2017 were included in the study. Patients with prior valvular surgery, history of HF, and baseline abnormal TR and TRPG were excluded. Finally, a total of 1075 patients were enrolled in this study. Progressive TR was defined as increased TR grade of ≥2 degrees and TRPG o
