Chordal transfer for repair of anterior leaflet prolapse.
A variety of techniques have been developed for repair of prolapse of the anterior leaflet of the mitral valve. At The Cleveland Clinic Foundation, we favor chordal transfer for this entity. In most instances, normal chordae with a strip of leaflet tissue are transferred from the posterior leaflet to the free edge of the unsupported anterior leaflet; the posterior leaflet is repaired in standard fashion employed for quadrangular resection. In selected cases, chordal transfer is accomplished by transfer of secondary anterior leaflet chordae to the unsupported free edge. Because normal chordae are used in both instances, there is no need for measurement of chordae or judgment of their length. With this technique for correction of anterior leaflet prolapse, 5-year freedom from reoperation after mitral valve repair is 96%.
