In addition, the proportion of aortic valves with bicuspid morphology and small annulus (\u226421\u2009mm) was 28% and 38.9%, respectively. The mean aortic cross\u2010clamp time was 106\u2009\u00b1\u200913.8\u2009min, mean cardiopulmonary bypass time was 136.7\u2009\u00b1\u200918.5\u2009min, and 2.8% of all patients required conversion to prosthetic valve replacement surgery. The mean follow\u2010up time was 26.4 months (12\u201342 months), the survival rate was 95.8%, the reoperation rate was 2.8%, and rate of postoperative moderate or higher aortic valve regurgitation was 4.2%. Postoperative valvular hemodynamics was favorable, with a peak pressure gradient of 16.1\u2009mmHg and an effective orifice area index of 2.3\u2009cm\n                      <jats:sup>2<\/jats:sup>\n                      .\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This procedure was safe and effective, with favorable valvular hemodynamics and a low rate of valvular degeneration.
