Surgical Treatment of Cor Triatriatum in a Geriatric Patient: a Rare Reason for Atrial Fibrillation and Stroke

Abstract

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. A 68-year-old patient was referred to our cardiothoracic surgery department following two-dimensional transthoracic echocardiography and a diagnosis of cor triatriatum. Echocardiography was performed due to stroke and atrial fibrillation. Echocardiography revealed 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. Cor triatriatum in geriatric patients is a rare congenital cardiac abnormality and can be a reason for atrial fibrillation and stroke. The treatment of choice is surgery.
