Cor Triatriatum Can Coexist With Common Pulmonary Venous Atresia.

Abstract

Surgical treatment was very urgently carried out in an extremely cyanotic newborn with common pulmonary venous atresia. The diagnosis was confirmed during the procedure, and the common venous chamber was anastomosed to the left atrium through a transverse incision onto the right and the left atria. Unfortunately, pulmonary hypertension persisted during the postoperative course and even got worse gradually. Computed tomography eventually illustrated residual cor triatriatum. The initial atriotomy had been entirely above the diaphragm within the left atrium. Consequently, the abnormal structure had been overlooked. The patient is doing well 1 month after the surgical revision. Pulmonary hypertension disappeared.
