Atresia tricuspídea asociada a tronco común: reporte de un caso / Tricuspid atresia associated with common trunk: a case report

The tricuspid atresia associated with persistent truncus arteriosus is a rare anomaly. A case is presented of one male patient of three months age in which was detected a cardiac murmur. The diagnosis was made by echocardiography and confirmed by cardiac catheterization. The first step of the palliation was done with disconnection of the trunk of the pulmonary artery combined with a systemic- to- pulmonary shunt of 4 mm. The patient died 24 hours later for persistent metabolic acidosis.
