Hancock porcine xenograft was implanted in 71 patients from 1977 to 1979, ionescu-Shiley pericardial xenograft (standard model) in 271 patients from 1979 to 1983, and Bjork-Shiley tilting disc valve in 194 from 1978 to 1986.
In aortic position, no any significant difference among three valve types could be demonstrated in the actuarial surviva and freedom from thromboemblism and valve infection, while the actuarial freedom from valve dysfunctin in lonescu-Shiley valve was significantly lower than that in other two valves.
Björk-Shiley valve in mitral position showed satisfactory clinical performance in terms of valverelated complicatins and survival in comparison with two types of bioprosthetic valves.
In our conclusion at present time, Björk-Shiley valve is suitable for the first choice of both aortic and mitral valve prostheses. In case of valve replacement with a bioprosthesis, however, porcine aortic valve is a better choice for aortic, and bovine pericardial valve likely for mitral replacement.
