A EIGHTEEN-YEAR EVALUATION OF THE Björk-Shiley VALVE PROSTHESIS
We evaluated the long-term (18 years) results of 356 patients undergoing valve replacement with Björk-Shiley valve prosthesis (aortic, 212 ; mitral 120 ; double valve, 24) between 1970 and 1988. Actuaria survival rates were 90％ (18 years) for AVR, 80％ ‘years) for MVR and 90％ (8 years) for DVR. Actuarial rates of thromboembolism were 99％ (18 years) for AVR, 98％ (8 years) for MVR and 94％ (8 years) for DVR. Actuarial rates of freedom from events (including valve failure, thromboembolism, reoperation and prosthetic valve endocardiotis) were 82％ (18 years) for AVR, 95％ (8 years) and 94％ (8 years) for DVR. There were no differences in these results among spherical disc, convexo-concave disc and monostrut valve.
In conclusion, this study demonstrated that Björk-Shiley valve showed a low incidence of postoperative events. These results endorse our choice of the Björk-Shiley.
