摘要: Mitral valve plasty has superseded replacement as the standard technique for treating degenerative mitral prolapse. Quadrangular resection is considered gold posterior leaflet Chordal was first developed to treat anterior and subsequently became widely used leaflet, after which a new version of that did not involve local annular plication. In era mini-thoracotomy, premeasured loop simple adopt durable quadrangular resection. However, there controversy surrounding whether or chordal optimal technique. The curative because it removes main pathologic lesion. disadvantage can be complicated often requires advanced surgical skills. contrast, pathologically leaves behind redundant leaflet. long-term results appear equivalent in many reports. Functionally, retains greater motion with lower trans-mitral pressure gradient than Moreover, yields uniform results. depends on involved, Barlow non-Barlow disease state, mini-thoracotomy sternotomy approach used. For repair, most superior reliable using newer approach, skilled surgeon.
