SELECTION OF VALVE PROSTHESIS, REOPERATION AND LATE RESULT
―SURGICAL TECHNIQUE OF REOPERATION WITH Björk-Shiley PROSTHESIS―

Late result of Björk-Shiley prosthesis selected in the aortic and mitral position for valve replacement was reviewed on 222 cases in our 10 years clinical experience. Late survival was 93.8％ (5 yrs), 83％ (10 yrs) in the aortic position, 94％ (5 yrs) and 80％ (10 yrs) in the mitral position. Valve-related complication by Björk-Shiley prosthesis was very low in incidence as compared with that published by other institution with respects to thromboembolism, prosthetic valve elldocarditis, reoperation, anticoagulation-related bleeding. Inflammatory aortic valve disease which developed valve detachment in the aortic position with Björk-Shiley valve was treated with double-suture technique in the aortic annulus and fixation of the graft with the inside of sinus of Valsalva, en-bloc reconstruction with composite graft using Björk-Shiley valve inside of the sinus Valsalva without touch to coroary ostium. The other surgical procedure was translocation method using Björk-Shiley prosthesis. Our clinical results suggest that Björk-Shiley prosthesis is still recommended in the aortic and mitral positions from low incidence of valve-related complication and good late survival.
