[A case of cor triatriatum with atrial septal defect in an adult].
A surgical treatment of a 54 year-old female with cor triatriatum was reported. Two dimensional echocardiography had demonstrated an abnormal septum in the left atrium. The abnormal septum had a 2 x 1 cm fenestration and existed between the left and right pulmonary veins. Preoperatively, we had misjudged the septum as ASD and misdiagnosed this case as PAPVC. During surgery we found that there was the accessory atrial chamber posterior to the true ASD. The accessory chamber received right pulmonary veins and connected to the left atrium. The left pulmonary veins connected to the left atrium normally behind the abnormal septum. We diagnosed this case as Lucas-Shmidt IIIA1 type cor triatriatum with ASD. The abnormal septum was resected, and the ASD was closed with a bovine pericardium. The postoperative course was uneventful and she was discharged 19 days after the operation.
