title: Closed mitral valvotomy.
abstract: The results of closed mitral valvotomy operations in 359 patients operated on from August 1957 to October 1974 were assessed at July 1975. About 60% of the patients were in good health. These results suggest that there is still a place for closed mitral valvotomy in carefully selected cases.
