Surgical Treatment of Mitral Stenosis: Survival Rales in 500 Operated Patients

Abstract
500 consecutive patients with mitral stenosis subjected to surgery are reviewed and survival rates calculated. Survival rates are less than for a comparable normal population, but significantly higher than for patients with mitral stenosis under medical management. For patients in functional Class II with sinus rhythm, the survival rates are identical for operated and un-operated patients, but as 85.6% of the operated patients had subjective improvement, commissurotomy is also recommended for patients in this group.
