This report reviews the results obtained with the current models of the Silastic ball valve, classifying the experience with the mitral and aortic models into the periods (formula: see text) before and after 1973. Valve failure is defined according to the Stanford method and includes any valve-related death or complication necessitating valve removal (there have been no mechanical failures). Comparison of the valve model used today with the same model used in the late 1960s shows that the results have improved dramatically, especially with regard to thromboembolism. The results obtained with valves implanted after 1973 compare favorably with those of other contemporary valves introduced in the early 1970s.
本报告回顾了使用当前硅橡胶球阀模型所取得的结果，将二尖瓣和主动脉瓣模型的使用经验分为1973年之前和之后两个时期（公式：见正文）。瓣膜失效根据斯坦福方法定义，包括任何与瓣膜相关的死亡或需要移除瓣膜的并发症（未发生机械故障）。将如今使用的瓣膜模型与20世纪60年代末使用的相同模型进行比较，结果显示有了显著改善，尤其是在血栓栓塞方面。1973年之后植入瓣膜所取得的结果与20世纪70年代初推出的其他同期瓣膜相比具有优势。
