Four patients with mitral regurgitation due to torn chordae of the mitral posterior leaflet underwent mitral valvuloplasty. Standard operation was McGoon's procedure which was sometimes combined with Kay's annulorrhaphy. There were no sign of mitral insufficiency and/or stenosis in all patients revealed by the post-operative cardiac catheterization and all of them are on good health. Then, our plans of mitral posterior valvuloplasty for mitral regurgitation are as follows: A resected area is not beyond 33% of the posterior leaflet and the target mitral valve area after valvuloplasty is 2.8 cm2.
