[Congenital tricuspid insufficiency due to valvular dysplasia]. / L'insufficienza tricuspidale congenita da displasia valvolare.

A case of congenital tricuspid incompetence in a 39 year old woman is reported. The patient, who was in suffering congestive heart failure, had no history of trauma, myocardial infarction, rheumatic fever, infective endocarditis. Right ventriculography and right atrial pressure recording both showed signs of severe tricuspid insufficiency. Echocardiography showed dilatation of the right ventricle and atrium, and the lack of normal systolic coaptation of anterior and septal tricuspid leaflets, while contrast echocardiography gave direct evidence of regurgitation. Valvular replacement with a bioprosthesis was carried out. The diagnosis of congenital tricuspid incompetence was confirmed at operation. The patient is asymptomatic at one year follow up.
