[Mitral valve repair with artificial chordal creation].

To achieve optimal long-term result of mitral valve repair, artificial chordae creation has got to be an important technique. Artificial chordae creation can preserve leaflet motion of the posterior mitral leaflet and soft coaptation area. Loop technique is suitable technique for creation of multiple artificial chordae, especially in minimally invasive minithoracotomy setting. Loop-in-loop technique is a new technique to realize easy adjusting of the length of the neochordae using slippery Gore-Tex suture. Loop-in-loop technique helps surgeons to afford variety of mitral valve repair techniques and manage complex mitral valve pathologies.
