Surgical Repair Results of Cor Triatriatum Sinister in 5 Cases

As a rare congenital defect, cor triatriatum sinister represents only 0.1% -0.4% of congenital cardiac anomalies. Depending on the accompanying symptoms and the degree of obstruction, cor triatriatum sinister is usual for patients to present in infancy and early childhood, although some cases remain undetected until adult life. We described 5 patients with cor triatriatum sinister who underwent operation in our institution. Five patients underwent surgical correction of cor triatriatum sinister were seen at Affiliated Hospital of Guilin Medical University between January 2005 and December 2015. The demographic characteristics and surgical results of these patients are outlined in this retrospective study. There were 4 males and 1 female with a mean age of 11.4 years (age range, 1 year to 27 years). The surgical approach consists of right atriotomy, excision of the obstructing membrane, and repair of the associated intracardiac anomalies. After an uneventful postoperative hospital stay, all patients were discharged 6–8 days postoperatively. Patients were followed up from 15 months to 12 years and were symptom free. There were no recurrence after surgical repair of the cor triatriatum sinister. Surgical treatment of cor triatriatum sinister provides satisfactory early and mid-term survival with low risk for additional intervention.
