Abstract

BACKGROUND: Transcatheter aortic valve implantation (TAVI) has emerged as a safe and effective alternative to surgical replacement for tricuspid aortic valve (TAV) stenosis. However, utilization of TAVI for aortic stenosis in bicuspid aortic valve (BAV) compared to TAV remains controversial. METHODS: We queried online databases with various keywords to identify relevant articles. We compared major cardiovascular events and procedural outcomes using a random effect model to calculate odds ratios (OR). RESULTS: We included a total of 22 studies comprising 189,693 patients (BAV 12,669 vs. TAV 177,024). In the pooled analysis, there were no difference in TAVI for BAV vs. TAV for all-cause mortality, cardiovascular mortality, myocardial infarction (MI), vascular complications, acute kidney injury (AKI), coronary occlusion, annulus rupture, and reintervention/reoperation between the groups. The incidence of stroke (OR 1.24; 95% CI 1.1-1.39), paravalvular leak (PVLR) (OR 1.42; 95% CI 1.26-1.61), and the need for pacemaker (OR 1.15; 95% CI 1.06-1.26) was less in the TAV group compared to the BAV group, while incidence of life-threatening bleeding was higher in the TAV group. Subgroup analysis mirrored pooled outcomes except for all-cause mortality. CONCLUSION: The use of TAVI for the treatment of aortic stenosis in selective BAV appears to be safe and effective.
