[Surgical correction of mitral valve prolapse].

Thirty-five patients with mitral valve prolapse were repaired at Fu Wai Hospital in Beijing between Jan. 1988 and June, 1993. 20 males and 15 females of them aged ranging from 7 to 52 years. 9 patients was less than 14 years old in this group. The mitral prolapse were caused by degeneration, congenital heart disease, trauma and rheumatic heart disease. The mitral anterior leaflet were eroded in 7 patients, posterior leaflet in 26 patients, both anterior and posterior leaflets in 2 patients. The dilation of the mitral annulus, rupture and prolongation of chordae and defect in the leaflets were found in these patients. The reconstruction of mitral valve were performed in all patients under cardiopulmonary bypass using the resection or plication of the prolapse parts of the leaflets or reduce the diameter of mitral annulus with a carpentier ring. The results were satisfactory without mortality in hospital or in following-up period. The indication and method of the operation were discussed.
