A simple method for determining the length of artificial chordae in mitral reconstructive operations is described. A small tourniquet is used for fine adjustment of the length of polytetrafluoroethylene stitches before tying them during leaking test. We have used this technique in 10 consecutive patients with anterior mitral leaflet prolapse since August 1992. Intraoperative transesophageal echocardiography revealed no or only trace mitral regurgitation after valve repair in all cases. This method minimized the time of determining the proper length of artificial chordae and achieved good results.
描述了一种在二尖瓣重建手术中确定人工腱索长度的简单方法。在泄漏测试期间，使用一个小止血带来精细调整聚四氟乙烯缝线的长度，然后再打结。自1992年8月以来，我们已将该技术应用于连续10例二尖瓣前叶脱垂患者。术中经食管超声心动图显示，所有病例在瓣膜修复后均无二尖瓣反流或仅有微量二尖瓣反流。该方法缩短了确定人工腱索合适长度的时间，并取得了良好的效果。
