Neochord Replacement for Mitral Valve Repair

摘要: Mitral repairs should be directed toward re-establishing the normal annular geometry with adequate posterior and anterior leaflet coaptation during systole. In majority of insufficient degenerative (i.e. myxomatous valves), a segment is flail either from ruptured or elongated chords. Previously, most mitral valve were done by resecting large suture reconstruction performing an plication. Many these complex not embraced all cardiac surgeons, leading to prosthetic replacement. Moreover, others found results varied in reproducibility. Herein, we describe technique, developed at Leipzig Heart Center, that simplifies reduction involved appropriate level. The technique very reproducible mainstay our repair strategy. Using PTFE material, multiple “neochord” loops are measured fabricated into cluster. base this cluster attached correct papillary muscle, each loop sutured along effected segment, establishing generous area systolic coaptation. Thus, prolapsed leaflets (Type II, Carpentier) has become simplified, method can reproduced surgeons.
