Predictive Factors for Permanent Pacemaker Implantation and Mortality after Transcatheter Aortic Valve Replacement in Patients with Pre-Existing Atrial Fibrillation.

ABSTRACT:

Introduction

Atrial fibrillation (AF) is the most common arrhythmia among patients undergoing transcatheter aortic valve replacement (TAVR). Post-TAVR permanent pacemaker implantation (PPI) predictors for patients in sinus rhythm were studied. However, scarce data are available about patients with AF. The aim of the study was to assess the prevalence of AF among patient undergoing TAVR, to identify predictors of PPI, and to study the association between PPI and long-term mortality.

Methods

A historical cohort study of all patients who underwent TAVR between 2008 and 2022 in a large tertiary medical center was conducted. Patients with prior aortic valve bioprosthesis or pacemakers were excluded. Thirty-day PPI and 3-year mortality were studied. Univariate and multivariable an
