The midterm outcomes of AVNeo using autologous pericardium were satisfactory in 850 patients with various aortic valve diseases. However, further randomized, multicenter prospective studies are needed to confirm the results of the current study.

Original aortic valve reconstruction was feasible in patients with various aortic valve diseases. Long-term data will be disclosed in the future.

Aortic valve disease is usually treated by prosthetic valve replacement. We have performed aortic valve plasty (AVP) using glutaraldehyde-treated autologous pericardium. AVP was performed for 88 patients from April 2007 through August 2009. Sixty-five patients had aortic stenosis, and 23 patients had aortic regurgitation (AR). Twenty-one patients showed bicuspid aortic valves, and one patient 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 glutaraldehyde-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 patients had echocardiography one year after surgery. The peak PG became 12.9±5.8 mmHg. Ten patients showed no AR, 20 patients showed trivial AR, and two patients showed mild AR. Freedom from reoperation is 100% at three years follow-up.
