Chordal replacement for both minimally invasive and conventional mitral valve surgery using premeasured Gore-Tex loops.
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.
