We report a case of severe aortic regurgitation occurring immediately after the insertion of a mitral annuloplasty ring. On transesophageal echocardiography, regurgitation was found to originate from the retracted left coronary cusp. On direct examination, part of the aortic wall was folded, but no suture could be identified. It was reasoned that tension created by the ring caused the retraction. The problem was corrected by releasing three sutures on the ring. Postoperative course was uneventful.
我们报告一例在二尖瓣环成形环植入后立即发生严重主动脉瓣反流的病例。经食管超声心动图检查发现，反流源自左冠状动脉瓣叶回缩。直接检查时，发现部分主动脉壁折叠，但未发现缝线。据推测，环产生的张力导致了瓣叶回缩。通过松开环上的三根缝线纠正了该问题。术后过程顺利。
