Of the 61 patients, 16 had a bicuspid aortic valve, and 5 had infective endocarditis. The preoperative peak and mean gradient pressure gradients were 91.7\u2009\u00b1\u200916.1\u2009mm\u2009Hg and 55.3\u2009\u00b1\u200910.3\u2009mm\u2009Hg, respectively. Surgery was performed via a full or partial sternotomy. The procedure was successful in 59 cases. Two patients were converted to prosthetic valve replacement. The aortic crossclamp time was 110.9\u2009\u00b1\u200920.5 minutes. Intraoperative transesophageal echocardiography showed a mean pressure gradient of 8\u2009\u00b1\u20092\u2009mm\u2009Hg and an aortic valve area of 3.04\u2009\u00b1\u20090.44 cm\n                      <jats:sup>2<\/jats:sup>\n                      . The mean follow-up period was 18.5\u2009\u00b1\u20095.7 months. One patient died in hospital due to cardiac tamponade. One patient underwent reoperation due to infective endocarditis 6 months after surgery. Another died at 8 months after surgery due to a mediastinal abscess.
