ABSTRACT
Introduction Tricuspid stenosis (TS) is a very uncommon valvular heart disease. It is almost always of rheumatic origin and virtually never occurs as an isolated lesion.1 Its incidence may be underestimated because it is commonly overlooked, particularly when associated with mitral stenosis. Tricuspid valve pathology is present at autopsy in about 15% of patients with rheumatic heart disease and is of clinical significance in only about 5% of cases.2 But organic tricuspid valve disease is more common in India than in the affluent countries and has been reported to occur in hearts of more than onethird of patients with rheumatic heart disease studied at autopsy in the subcontinent.3 Other causes of obstruction to right atrial emptying are unusual – congenital, carcinoid syndrome, pericardial constriction, extracardiac tumors, and vegetations following infective endocarditis.
