title: Congenital tricuspid incompetence simulating pulmonary atresia with intact ventricular septum: a report of two cases.
abstract: Two infants with isolated congenital tricuspid incompetence appeared to have associated right ventricular outflow tract obstruction at diagnostic evaluation, including catheterization and cineangiography. One infant died during surgery; the other improved rapidly and survived with medical therapy. We discuss the problem of establishing the presence of patency of the right ventricular outflow tract in infants with massive tricuspid incompetence and outline an approach to the management of infants whose diagnosis remains unclear even after careful evaluation.
