Calcific tricuspid incompetence in childhood.

Calcification of the tricuspid valve is rare. Previously reported cases have been associated with increased pressure in the right ventricle or a left-to-right shunt proximal to the tricuspid valve. Furthermore, the calcification has not been evident until the fifth decade of life or later. A case is reported here in which moderately severe tricuspid valve calcification was present ,at I0 years of age. There was isolated tricuspid incompetence, in itself an uncommon disorder, with normal right ventricular pressure and no intracardiac shunting.
