Surgical treatment of commissural prolapse: case report and review of the options.

Repair of commissural prolapse associated with chordal rupture may represent a challenging problem for the cardiac surgeon. The case of a patient with chronic mitral regurgitation and prolapse of the posterior commissural area associated with chordal rupture is presented. A technique was proposed that involved partial resection of the degenerative leaflet segment, plication of the posterior annulus and chordal transfer to create a neocommissure.
