Between 1976 and 1983, 435 patients underwent aortic valve replacement (AVR) with Bjork Shiley prostheses. Standard aortic Bjork Shiley prostheses (ABP) were used in 150 patients (Group I) and a reversed mitral Bjork Shiley prostheses in 285 (MBP in 250 and MBC in 35) patients (Group II). There was no significant difference in the number of the patients with valve calcification or the size of aortic root in the 2 groups. There was no significant difference in the early mortality in these two groups. The total follow up period in Group I was 912 years and 2130 years in Group II. The incidence of major aseptic prosthetic dehiscence and valve occlusion with tissue ingrowth were higher in Group I than in Group II. Reversed Bjork Shiley mitral valve prosthesis was successfully used in aortic position with reduced incidence of valve related complications.
1976年至1983年间，435例患者接受了使用Bjork Shiley人工心脏瓣膜的主动脉瓣置换术（AVR）。150例患者（第一组）使用标准主动脉Bjork Shiley人工瓣膜（ABP），285例患者（第二组，其中250例使用MBP，35例使用MBC）使用反转二尖瓣Bjork Shiley人工瓣膜。两组患者中瓣膜钙化的数量或主动脉根部大小无显著差异。两组的早期死亡率无显著差异。第一组的总随访期为912年，第二组为2130年。第一组中严重无菌性人工瓣膜裂开和组织长入导致瓣膜阻塞的发生率高于第二组。反转的Bjork Shiley二尖瓣人工瓣膜成功用于主动脉位置，瓣膜相关并发症的发生率降低。
