Severe aortic regurgitation developed in three patients after aortic valve replacement within six months due to long sutures prolapsing across the "annulus" of Björk-Shiley prosthesis. At reoperation the offending sutures were trimmed or tucked back to the aortic wall to eliminate aortic regurgitation. Prolapse of unravelled knots may be the likely cause. Everting the sewing skirt during the first replacement may prevent this complication.
三例患者在主动脉瓣置换术后六个月内出现严重主动脉瓣反流，原因是长缝线跨过Björk-Shiley人工瓣膜的“瓣环”脱垂。再次手术时，将有问题的缝线修剪或塞回主动脉壁以消除主动脉瓣反流。缝线结松开脱垂可能是其原因。首次置换时将缝合裙外翻可预防此并发症。
