RESUMO
The present article describes the management of three neonates with tricuspid atresia and duct dependent pulmonary circulation referred to the Instituto de Coração de Pernambuco in November 1992. A brief literature review of the condition is added. Full diagnosis was established with echocardiography at the neonatal ICU; all of them were intubated, mechanically ventilated and started on PGE1 and Dopamine infusions. Within 10h to 24h of hospitalization, all were submitted to surgery. One patient died on the third postoperative day the other two were discharged in good clinical condition. Despite the small our experience shows that clinical and surgical management of tricuspid atresia with duct dependent pulmonary circulation can reach satisfactory results in our region providing that early diagnosis of cyanotic heart disease is established by the pediatrician with timely transferal of the neonate to a reference center in paediatric cardiology.
