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.
