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.

Abstract OBJECTIVES Elective treatment of aortic valve disease by transcatheter aortic valve replacement (TAVR) is becoming increasingly popular, even in patients with low risk and intermediate risk. Even patients with a bicuspid aortic valve (BAV) are increasingly considered eligible for TAVR. Permanent pacemaker implantation (PMI) is a known—frequently understated—complication of TAVR affecting 9–15% of TAVR patients with a potentially significant impact on longevity and quality of life. BAV patients are affected by the highest PMI rates, although they are frequently younger compared to their tricuspid peers. The aim of the study is to report benchmark data—from a high-volume centre (with a competitive TAVR programme) on PMI after isolated surgical aortic valve replacement (SAVR) in patients with BAV and tricuspid aortic valve (TAV). METHODS We performed a retrospective single-centre analysis on 4154 patients receiving isolated SAVRs (w/o concomitant procedures), between 2000 and 2019, of whom 1108 had BAV (27%). PMI rate and early- and long-term outcomes were analysed. For better comparability of these demographically unequal cohorts, 1:1 nearest neighbour matching was performed. RESULTS At the time of SAVR, BAV patients were on average 10 years younger than their TAV peers (59.7 ± 12 vs 69.3 ± 9; P < 0.001) and had less comorbidities; all relevant characteristics were equally balanced after statistical matching. Overall PMI rate was significantly higher in BAV patients (5.4% vs 3.8%; P = 0.03). BAV required PMI exclusively (100%) and TAV required predominately (96%) for persistent postoperative high-degree atrioventricular block. After matching, the PMI rate was similar (5.1% vs 4.4%, P = 0.5). In-hospital mortality in the matched cohort was 1% in both groups. Long-term survival was more favourable in BAV patients (94% vs 90% in TAV at 5 years; 89% vs 82% in TAV at 9 years; P = 0.013). CONCLUSIONS With SAVR, the overall incidence of PMI among BAV patients seems significantly higher; however, after propensity matching, no difference in PMI rates between BAV and TAV is evident. The PMI rate was remarkably lower among BAV patients after SAVR compared to the reported incidence after TAVR.
