Aortic valve reconstruction using self-developed @entity886 in XXXX .

@entity1 @entity3584 @entity886 @entity337 @entity472
@entity886 is usually treated by prosthetic valve replacement. We have performed aortic valve plasty (AVP) using @entity3584 -treated autologous pericardium. AVP was performed for 88 @entity1 from April 2007 through August 2009. Sixty-five @entity1 had @entity472 , and 23 @entity1 had @entity337 ( @entity337 ). Twenty-one @entity1 showed bicuspid aortic valves, and one @entity1 showed quadricuspid valve. There were 43 males and 45 females. Their mean age was 70.6  10.5 years old. First, diseased leaflets excised. Then, the distance between each commissure was measured. The new leaflet were trimmed with an original template from a @entity3584 -treated autologous pericardium sample. Finally, the annular margin of the pericardial leaflet was running sutured to each annulus. There was no operative mortality or embolic event. Postoperative echocardiography revealed a mean peak pressure gradient (PG) of 19.0  9.1 mmHg one week after surgery. Thirty-two @entity1 had echocardiography one year after surgery. The peak PG became 12.9  5.8 mmHg. Ten @entity1 showed no @entity337 , 20 @entity1 showed trivial @entity337 , and two @entity1 showed mild @entity337 . Freedom from reoperation is 100% at three years follow-up.
