Surgical treatment of cor triatriatum in a geriatric patient: A rare reason for atrial fibrillation and stroke

Introduction: The incidence of cor triatriatum among neonates with congenital heart disease is only 0.1% to 0.4%. The diagnosis in adults is extremely rare. Case: A 68 years old patient was referred to our cardiovascular surgery department following transthoracic echocardiography and a diagnosis of cor triatriatum. Echocardiography was performed due to stroke and atrial fibrillation. Echocardiography showed a membrane in the left atrium, with the typical presentation of cor triatriatum type 1A. We operated the patient and excised the membrane. The operation was completed conventionally with sinus rhythm. Conclusion: Cor triatriatum in geriatrics is a rare congenital cardiac abnormality and can be a reason for atrial fibrilation and stroke. Treatment of choice is surgery.
