Valvotomy in calcific mitral stenosis

Abstract
The results of transventricular mitral valvotomy in 50 cases of heavily calcified mitral stenosis are presented. The mortality and quality of results in patients undergoing a first valvotomy were more satisfactory than in patients undergoing a second operation. Associated mitral incompetence has an adverse effect on the results, particularly after a second operation. As a result, it is suggested that closed valvotomy, in these circumstances, is only acceptable for patients who are undergoing a first operation and who have minimal or no regurgitation. Valve replacement is advised for all other cases.
