The mitral annulus can be rendered hostile by several uncommon clinical situations such as infective endocarditis, calcification, or previous valve surgery. These can all lead to difficulties seating a prosthesis or annuloplasty ring. The posterior mitral annulus or anteriorly the intervalvar fibrous body can be affected. These situations continue to pose a formidable technical challenge to the cardiac surgeon in the operating room. We review the evidence around solutions for these problems with the intent of giving surgeons an overview of techniques to address these issues.
二尖瓣环在几种罕见的临床情况下可能会变得不稳定，如感染性心内膜炎、钙化或先前的瓣膜手术。这些情况都可能导致假体或瓣环成形术环难以放置。后二尖瓣环或前间隔纤维体可能会受到影响。这些情况继续给手术室中的心脏外科医生带来巨大的技术挑战。我们回顾了这些问题的解决方案的证据，旨在让外科医生对解决这些问题的技术有一个全面的了解。
