【Abstract】 From June, 1976 to May, 1983, 203 patients underwent valve replacement, preo-perative function in N. H. Y. A was as following: class (II) 16 Cases (8%), class f 102 cases (50%). class (IV) 85 cases (42%), of all cases, 23 cases were perfomed replacements of aortic valve, 157 cases-mitral valve, 23 cases-aortic and mitral valve, Several types of artificial valve were used: pig valves-60 sets, Bjork-Shiley valves-42 sets, Shanghai disc valves-124 sets. The follow-up time was the mean 2.3 years.The results revealed that the effect of artificial valve replacement in this group was good: early death-22 cases (10.8%), late death-8 cases (1.9% case-years). After operation, the heart functions improved apparently (average 1.7 grades). Of all cases 81% patients returned to the jobs their used to do. It must be emphasized that surgical treatment on advanced patients do not be negleted when one makes on an effect in enhancing curadive effect and reducing the mortality. We discussed major late post-operation complication and their treatments. A comparison among the artificial valves, which were used in this group, was made. We propose that mechanical valves are the first choice for valves replacement, and biologic valves are the second.更多还原
