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.

确定人造腱索的最佳长度，然后有效地固定它们，是二尖瓣修复的主要挑战。我们用于测量和稳定新腱索的技术包括将聚丙烯缝线环绑在瓣环成形术环上。我们对4例因变性后叶（P2）脱垂和fl腱索而发生中度至重度二尖瓣反流的患者使用了该方法。术中盐水检查和术后经食道超声心动图检查的结果仅显示轻度供血不足。术后1个月，所有4例患者的超声心动图均显示微不足道反流。我们认为这种简单，精确的方法来调节和稳定人造腱索在二尖瓣修复中将是有利的。
