Abstract

Background As transcatheter aortic valve replacement (TAVR) technology expands to healthy and lower-risk populations, the burden and predictors of procedure-related complications including the need for permanent pacemaker (PPM) implantation needs to be identified.

Methods and Results Digital databases were systematically searched to identify studies reporting the incidence of PPM implantation after TAVR. A random- and fixed-effects model was used to calculate unadjusted odds ratios (OR) for all predictors. A total of 78 studies, recruiting 31 261 patients were included in the final analysis. Overall, 6212 patients required a PPM, with a mean of 18.9% PPM per study and net rate ranging from 0.16% to 51%. The pooled estimates on a random-effects model indicated significantly higher odds of post-TAVR PPM implantation for men (OR, 1.16; 95% CI, 1.04-1.28); for patients with baseline mobitz type-1 second-degree atrioventricular block (OR, 3.13; 95% CI, 1.64-5.93), left anterior hemiblock (OR, 1.43; 95% CI, 1.09-1.86), bifascicular block (OR, 2.59; 95% CI, 1.52-4.42), right bundle-branch block (OR, 2.48; 95% CI, 2.17-2.83), and for periprocedural atriorventricular block (OR, 4.17; 95% CI, 2.69-6.46). The mechanically expandable valves had 1.44 (95% CI, 1.18-1.76), while self-expandable valves had 1.93 (95% CI, 1.42-2.63) fold higher odds of PPM requirement compared with self-expandable and balloon-expandable valves, respectively.

Conclusions Male sex, baseline atrioventricular conduction delays, intraprocedural atrioventricular block, and use of mechanically expandable and self-expanding prosthesis served as positive predictors of PPM implantation in patients undergoing TAVR.
