Impact of Atrial Fibrillation Type on Outcomes of Transcatheter Aortic Valve Replacement for Aortic Stenosis: A Single-Center Analysis.

ABSTRACT:

Background

Atrial fibrillation (AF) is a recognized risk factor for mortality after transcatheter aortic valve replacement for severe aortic stenosis, but the impact of different types of AF on clinical outcomes remains unclear.

Methods

This retrospective study included 982 patients divided into 3 groups: no AF, paroxysmal AF, and nonparoxysmal AF (persistent or permanent). Clinical outcomes were analyzed using inverse probability weighting and multivariate models.

Results

There were 610, 211, and 161 patients in the no-AF, paroxysmal AF, and nonparoxysmal AF groups, respectively. For the entire cohort, the mean (SD) age was 82 (7.7) years, and the periprocedural, 1-year, and 5-year mortality rates were 2.0%, 12%, and 50%, respectively. After inverse probability weigh
