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.

AbstractBackgroundsThe risk of brain injury in bicuspid aortic valve (BAV) patients following transcatheter aortic valve replacement (TAVR) is currently unknown.Methods and ResultsA total of 204 consecutive severe aortic stenosis patients who underwent TAVR were enrolled. 83 (40.7%) patients were BAV patients and the other 121 patients were tricuspid aortic valve (TAV) patients. All patients received diffusion-weighted magnetic resonance imaging (DW-MRI) at baseline, 2 to 7 days after TAVR. Mean ages (mean ± SD: 75.8 ± 6.7 years vs. 78.9 ± 6.6 years, p = 0.004) and STS scores (6.0 ± 3.7 vs. 7.1 ± 4.2, p = 0.044) of the BAV and TAV patients were significantly different, while the stroke rates (2.4% vs. 1.7%, p = 0.704) were comparable between two groups. BAV patients were associated with higher number of new lesions (5.69 ± 6.22 vs. 3.50 ± 4.16, p = 0.008), total lesion volume [median(interquartile range): 290(70-930) mm3 vs. 140(35-480) mm3, p = 0.008], and the volume per lesion [70.0(45.0-115.0) mm3 vs. 57.5(24.5-93.0) mm3, p = 0.037] in DW-MRI. Moreover, the proportion of patients with lesions larger than 1cm3 (28.6% vs. 10.9%, p = 0.005) and the number of new lesions in the middle cerebral arteries zone (1.46 ± 2.07 vs. 0.98 ± 1.84, p = 0.039) and intermediate zone between the anterior cerebral and middle cerebral arteries (ACA/MCA) (1.07 ± 1.68 vs. 0.50 ± 1.05, p = 0.007), and between the vertebral artery and basilar artery (VA/BA) (1.01 ± 1.35 vs. 0.77 ± 1.44, p = 0.033) were higher in BAV patients than in TAV patients.ConclusionsBAV patients may encounter more severe brain injuries not only due to greater number of lesions but also due to larger lesion size, especially in the ACA/MCA, MCA and VA/BA lesions zone.
