title: Cor triatriatum: operative results in 25 patients.
abstract: Twenty-five patients with cor triatriatum underwent surgical correction at the Texas Heart Institute during a 21-year period from 1959 to 1980. Patients ranged in age from 4 months to 38 years. Diagnosis was established preoperatively in 14 patients (56%), at the time of operation for correction of associated lesions in 10 patients (40%), and during reoperation in 1 (4%). In the earlier part of this series, diagnosis was more common at the time of operation. Associated cardiovascular anomalies were present in 20 patients (80%), major anomalies in 14 others (56%). Simultaneous correction or palliation of associated lesions and total excision of the anomalous membrane were done in 18 patients utilizing temporary cardiopulmonary bypass. Cor triatriatum alone was repaired in 5 patients (20%) with the aid of extracorporeal circulation. Two patients underwent reoperation: 1 because of incomplete excision of the septum and the other because the condition had not been diagnosed during a first operation for correction of total anomalous pulmonary venous return. Excision of the membrane was accomplished utilizing the left atrium in 10 patients (40%), the right atrium in 12 (48%), or both in 3 (12%). Four patients (16%) died early after operation; all were infants who had severe associated cardiac anomalies. Among the 21 surviving patients, results were excellent in 20.
