Infectious lesions of the mitral ring sometimes cause so much damage that insertion of the prosthesis in its normal place is impossible. In such cases, artificial valves with a dacron flange can be implanted into the left atrium, just above the mitral ring, and sutured to the atrial wall. These valves are generally used in first or second re-operations for recurrent desinsertion, but they have proved so reliable that their use can be extended to primary mitral valve replacement in cases where extreme calcification of the mitral ring throws considerable doubt on the success of conventional techniques.
二尖瓣环的感染性病变有时会造成严重破坏，以至于无法将假体植入其正常位置。在这种情况下，可以将带有涤纶法兰的人工瓣膜植入左心房，就在二尖瓣环上方，并缝合到心房壁上。这些瓣膜通常用于复发性瓣膜脱开的首次或二次再次手术，但事实证明它们非常可靠，以至于在二尖瓣环极度钙化使传统技术的成功受到很大质疑的情况下，其应用范围可以扩大到原发性二尖瓣置换术。
