Four years' experience with 363 patients, in whom 360 mitral and 65 tricuspid prosthetic valves have been implanted with single continuous sutures, is presented. The occurrence of prosthetic valve detachment is particularly discussed. There were 4 cases of detachment of the prosthetic mitral valve and no cases of tricupsid dehiscence. All 4 patients with detached valves required reoperation. Calcifications that penetrate into the annulus and myxomatous degeneration of the valve are considered more important factors in the production of prosthetic cases so long as a uniform distribution of stitches is maintained (not too close to each other) and excessive tension in the suture line is avoided.
本文介绍了对363例患者的四年经验，这些患者中已使用单一连续缝合线植入了360个二尖瓣和65个三尖瓣人工瓣膜。特别讨论了人工瓣膜脱离的发生情况。有4例人工二尖瓣脱离，无三尖瓣裂开病例。所有4例瓣膜脱离患者均需再次手术。只要保持缝线均匀分布（彼此不要太靠近）并避免缝线处过度张力，那么穿透瓣环的钙化和瓣膜的黏液瘤样变性被认为是导致人工瓣膜病例的更重要因素。
