Abstract

The importance of preservation of subvalvular apparatus and valve-ventricular continuity during mitral valve replacement (MVR) has been suggested for many years. The chordal-sparing MVR has been shown to be superior to the standard MVR with chordal resection in terms of improved left ventricular function and has been considered to be a safe procedure. However, we encounter a rare case requiring early reoperation for bioprosthetic valve failure caused by preserved leaflets after chordal-sparing MVR.

摘要

多年来，二尖瓣置换术（MVR）期间保留瓣下结构和瓣膜 - 心室连续性的重要性已被提及。保留腱索的二尖瓣置换术在改善左心室功能方面已被证明优于标准的腱索切除二尖瓣置换术，并且被认为是一种安全的手术。然而，我们遇到了一例罕见病例，该病例因保留腱索的二尖瓣置换术后生物瓣膜因瓣叶残留导致功能衰竭而需要早期再次手术。
