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.
We describe an alternative step in the transatrial approach to the repair of ventricular septal defects. We temporarily detach the chorda of the obscuring tricuspid valve from its attachment to the septum to expose the ventricular septal defect.
