Is chordal insertion the procedure of choice in mitral valve repair?
Degenerative mitral valve disease is frequently represented by elongated and/or ruptured chordae tendineae which leads to prolapse of the mitral valve (MV) and, thus, to mitral regurgitation (MR). In such cases, MV surgery provides a curative treatment. A simple surgical procedure to address MV prolapse is to replace the diseased chordae tendineae by polytetrafluoroethylene (PTFE) sutures. This idea of chordae replacement was introduced by Frater and colleagues. They followed the attempt of completely replacing diseased chordae with PTFE sutures, a material very similar to native chordae in terms of biomechanical characteristics. Until today, several different techniques for implantation of neochordae in MV repair have been described with a very high rate of success and good long-term durability. Despite these promising results, the question remains whether chordal insertion is the procedure of choice in mitral valve repair?
