Tricuspid stenosis has been demonstrated to be present in 10% to 15%* of patients with valvular rheumatic heart disease. It is invariably associated with disease of other valves,3 and its occurrence as a result of etiological factors other than rheumatic fever is rare.† The effect on cardiovascular function, therefore, of the tricuspid stenosis usually is only a part of the total disturbance of multivalvular involvement and is present only in the late stages of rheumatic heart disease.

Nonetheless, in spite of the operative risk imposed by the severity of the cardiac involvement, stenosis of the tricuspid valve is amenable to surgical intervention. So far as we know,‡ only three cases of surgical correction have been reported. We believe, however, that tricuspid and mitral commissurotomy, as a one-stage procedure, is indicated in certain patients.

Experience with patients having both mitral and tricuspid stenosis of sufficient severity to warrant surgical intervention
