          Translated abstract

          Prosthetic valve replacement is the standard treatment for aortic valvulopathy. Due to the structural valve deterioration of biological prosthesis and the anticoagulation requirements of mechanical valves, the repair of aortic valve disease is receiving more attention in recent years. The Ozaki technique consists in the reconstruction of a trileaflet valve using autologous pericardium. We report our first two cases of successful reconstruction of the aortic valve using this technique with 12-month echocardiographic and 24-month clinical follow up.

              Aortic valve reconstruction using self-developed aortic valve plasty system in aortic valve disease.

              Shigeyuki Ozaki, Isamu Kawase, Hiromasa Yamashita … (2011)
              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.
