Cardiac Hemangioma Located in the Interatrial Septum: A Case Report and Literature Review

Cardiac hemangiomas are extremely rare benign tumors that can occur in any part of the heart. We report the case of an adult female with no history of structural heart disease or symptoms of discomfort. Cardiac ultrasound showed a mass on the right atrial surface of the atrial septum. Intraoperatively, the mass was identified within the atrial septum, at the junction of the inferior vena cava and the ostium of the coronary sinus. The mass did not enter the left or right atrial cavities. The mass was successfully removed, and cardiac hemangioma was confirmed by postoperative pathology. This report discusses the clinical manifestations, diagnostic approaches, and treatment options for cardiac hemangiomas based on an analysis of previously reported cases. Owing to the risk of arrhythmia in patients with hemangiomas in the atrial or ventricular septum, surgical resection is recommended.
