title: [Mitral valvuloplasty for the repair of mitral valve prolapse due to tendon rupture of the posterior leaflet in a father and son--case reports].
abstract: The use of mitral valvuloplasty for the repair of mitral valve prolapse in members of a family has been reported only rarely. Patient 1 was a 71-year-old man, and patient 2 the son of patient 1 was a 47-year-old man. Both patients had a grade 3/4 mitral valve regurgitation due to tendon rupture of the posterior leaflet. The procedure was quadrangular resection of the posterior leaflet with annulorrhaphy and ring annuloplasty. The results were good in both cases. Histopathological analysis of a specimen resected from the mitral valve revealed myxomatous degeneration in both cases. These case reports suggest that there is a genetic basis for mitral valve prolapse.
