Determining the optimal length of artificial chordae tendineae and then effectively securing them is a major challenge in mitral valve repair. Our technique for measuring and stabilizing neochordae involves tying a polypropylene suture loop onto the annuloplasty ring. We used this method in 4 patients who had moderate-to-severe mitral regurgitation from degenerative posterior leaflet (P2) prolapse and flail chordae. Results of intraoperative saline tests and postoperative transesophageal echocardiography revealed only mild insufficiency. One month postoperatively, echocardiograms showed trivial regurgitation in all 4 patients. We think that this simple, precise method for adjusting and stabilizing artificial chordae will be advantageous in mitral valve repair.
确定人工腱索的最佳长度并有效地固定它们是二尖瓣修复中的一项重大挑战。我们测量和稳定新腱索的技术包括将聚丙烯缝合环系在瓣环成形环上。我们将这种方法用于4例因退行性后叶（P2）脱垂和腱索连枷导致中重度二尖瓣反流的患者。术中盐水试验和术后经食管超声心动图结果显示仅有轻度反流。术后1个月，超声心动图显示所有4例患者均有微量反流。我们认为这种调整和稳定人工腱索的简单、精确方法在二尖瓣修复中具有优势。
