Abstract
Fracture of the short strut of the latest series of Björk-Shiley mitral valve prostheses occurred 12 months after implantation. The patient died despite emergency surgery to excise and replace the prosthesis. Björk-Shiley 29-33 mm valves with a 60 degree opening angle manufactured between February 1981 and March 1982 have a predicted strut fracture rate of 0.3% (three times greater than that of valves produced outside these dates). Unimplanted valves from this batch have now been recalled by the manufacturers.
摘要
最新一批 Björk-Shiley 二尖瓣假体的短支柱在植入 12 个月后发生骨折。尽管进行了紧急手术切除并更换假体，患者仍死亡。1981 年 2 月至 1982 年 3 月生产的开口角度为 60 度的 29 - 33 毫米 Björk-Shiley 瓣膜，预计支柱骨折率为 0.3%（比该日期之外生产的瓣膜高出两倍）。制造商现已召回这批未植入的瓣膜。
