The perioperative mortality was 0.7% in the BAV group and 3.6% in the TAV group (P\u2009=\u20090.079). Estimated survival at 5 years in the BAV versus TAV group was 97\u2009\u00b1\u20093% vs 80\u2009\u00b1\u20096%, respectively (P\u2009&amp;lt;\u20090.001). Freedom from reoperation at 5 years in the TAV versus BAV group was 96\u2009\u00b1\u20093% vs 93\u2009\u00b1\u20094%, respectively (P\u2009=\u20090.28). Grade 2 or more aortic valve regurgitation was noted in 9.9% of BAV patients and 11% of TAV patients (P\u2009=\u20090.66). Reoperation was predicted by cusp perforation [hazard ratio 15.86 (4.44\u201356.61); P\u2009&amp;lt;\u20090.001], the use of pericardial patch [hazard ratio 8.58 (1.96\u201337.53); P\u2009=\u20090.004] and aortic valve annulus diameter &amp;gt;27.5\u2009mm [hazard ratio 3.07 (0.99\u20139.58); P\u2009=\u20090.053].<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS<\/jats:title>\n                    <jats:p>BAV repair is as durable as TAV repair. BAV is not a predictor of a higher rate of reoperations. BAV repair yields survival comparable to expected. Cusp perforation, aortic valve annulus diameter &amp;gt;27.5\u2009mm and the use of pericardial patch adversely impact long-term outcome of aortic valve repair.<\/jats:p>\n
