Predictors of ventricular pacing burden after permanent pacemaker implantation following transcatheter aortic valve replacement.

ABSTRACT: BACKGROUND:In the era of an expanding use of transcatheter aortic valve replacement (TAVR), conduction disturbances and the requirement for permanent pacemaker (PPM) implantation remains a clinical concern. HYPOTHESIS:Using a single-center experience, we sought to identify predictors of ventricular pacing burden after TAVR in patients who required PPM implantation. METHODS:We conducted a retrospective study of 359 consecutive patients with symptomatic severe aortic valve stenosis who underwent TAVR at our institution between September 2013 and July 2019. Thirty patients (8.4%) required a PPM within 30?days after TAVR. Pre and post-TAVR electrocardiograms, pre-TAVR echocardiograms and computed tomography (CT), TAVR procedural details and post-TAVR device interrogation records at 1, 3, and 6 months were reviewed. RESULTS:Mean percentage of ventricular pacing (VP%) at 1, 3, and 6 months was 58%, 59%, and 56% respectively. Using univariate logistic regression analysis, patients who had low VP%?
