Twenty-seven patients were male and 59 were female. Mean age was 82.9\u2009\u00b1\u20092.5 years. Seventy-two patients had aortic stenosis and 14 had aortic regurgitation. Mean preoperative surgical annular diameter was 19.5\u2009\u00b1\u20092.5\u2009mm. There were 80 (90.7%) cases of small aortic annulus.

Concomitant procedures included coronary artery bypass grafting in 6, hemiarch aortic replacements in 6, 9 maze procedures, and some combinations. No conversion to valve replacement was required. Mean follow-up was 1243 days. There were 3 hospital deaths due to noncardiac causes. No reoperation was needed. Survival at 56 months was 87.0%. No thromboembolic event occurred. Echocardiography 3.5 years after surgery revealed an average peak pressure gradient of 14.6\u2009\u00b1\u20093.8\u2009mm Hg.
