Part of the complexity of mitral valve chordal replacement with expanded polytetrafluoroethylene (ePTFE) sutures is determining the correct replacement chordal length and knotting the ePTFE suture without sliding the knot. We describe a technique of measuring the required chordal length and making a "premeasured" Gore-Tex chordal loop that abolishes problems of inadvertently altering chordal length during fixation. This improves the reproducibility of chordal replacement surgery, and can be used both via conventional and minimally invasive approaches.
使用膨体聚四氟乙烯（ePTFE）缝线进行二尖瓣腱索置换的部分复杂性在于确定正确的置换腱索长度以及在不使结滑动的情况下将ePTFE缝线打结。我们描述了一种测量所需腱索长度并制作“预测量”的戈尔特斯（Gore-Tex）腱索环的技术，该技术消除了固定过程中意外改变腱索长度的问题。这提高了腱索置换手术的可重复性，并且可通过传统方法和微创方法使用。
