This study aimed to analyse the outcomes of surgical aortic valve replacement with a rapid-deployment bioprosthesis in patients with a BAV.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>Between May 2010 and December 2020, all consecutive patients who underwent RD-AVR at the Medical University of Vienna were included in our institutional database. Assessment of preoperative characteristics, operative outcomes, long-term survival and clinical events was performed. The outcomes of patients presenting with a native BAV were compared with a control group of patients with native tricuspid valve (TAV); reoperative aortic valve replacements were excluded.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Out of 816 patients, who underwent RD-AVR at our institution, 107 patients with a BAV, mean age 68 (standard deviation: 8) years, were compared with a control group of 690 patients with a TAV, mean age 74 (standard deviation: 7) years; patients presenting with a BAV were significantly younger than patients with a TAV (P &amp;lt; 0.001). Concomitant procedures were performed in 44 (41.1%) patients in the BAV group and in 339 (49.1%) patients in the TAV group (P = 0.123); surgery of the ascending aorta was necessary in 24 (22.4%) in the BAV group, compared with 29 (4.2%) in the control group (P &amp;lt; 0.001). The 5-year cumulative incidence of moderate-to-severe paravalvular regurgitation in the BAV group was 10.7% [95% confidence interval (CI): 4.2\u201320.7%] and 3.9% (95% CI: 2.4\u20136.1%) in the TAV group (P = 0.057). Reoperation with valve explantation due to non-structural valve dysfunction at 5 years was 2.8% (95% CI: 0.5\u20138.8%) in the BAV group, compared to 1.9% (95% CI: 1.0\u20133.2%) in the TAV cohort (P = 0.89). The overall long-term survival rate in the BAV group was 92% (95% CI: 81\u201397%) at 5 years and 88% (95% CI: 73\u201395%), at 10 years, significantly better compared to the TAV group (log-rank test P = 0.002).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>RD-AVR can be performed in patients with a BAV with convincingly medical outcomes. However, a trend to increased frequency of moderate\u2013severe paravalvular regurgitation was observed at long-term follow-up. Consequently, a different surgical approach, compared to tricuspid valves, with distinctly specific technical- and anatomical considerations and requirements, is recommended.<\/jats:p>\n
