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.
