Aortic Valve Leaflets Reconstruction (Ozaki Procedure) in Aortic Valve Diseases

an alternative way of repairing aortic valve, involving the use of autologous pericardium for the aortic leaflet reconstruction. Diseased leaflets are removed carefully. The distance between each commissure is measured with invented sizing apparatus. The new leaflet of the size corresponding to the measured value is trimmed with an original template from glutaraldehyde-treated autologous pericardium. Finally, the annular margin of the pericardial leaflet was running sutured with each annulus. Commissural coaptation was secured with additional sutures. The coaptation of three new leaflets were always insured with direct vision.
