Recent advances in the surgical treatment of mitral stenosis have made the diagnosis of tight mitral stenosis important. Evidence is accumulating that mitral commissurotomy performed in patients with tight mitral stenosis is of benefit and can be performed with a comparatively low mortality in selected cases. Patients with mild mitral stenosis and with severe mitral insufficiency or aortic valvular lesions may present somewhat similar pictures, but would not be candidates for surgical treatment until such time as operative approaches to the correction of mitral insufficiency or aortic insufficiency and stenosis have proved their worth. Although there is a tendency, at present, to limit the operation to those patients who show tight mitral stenosis without significant associated lesions, it seems possible that correction of the mitral stenosis may be of value whenever it is severe, regardless of associated lesions. The purpose of this presentation is to describe the factors that are
