Cavernous hemangioma of the mitral valve: a case report and review of literature

Abstract

Cardiac hemangiomas are rare cardiac tumors with fewer than 50 surgically treated cases reported in the literature. Incidence of valvular hemangiomas is extremely low, as cardiac valves are predominantly avascular structures. In this case report, we describe a 33-year-old woman who presented with progressively worsening cardiovascular symptoms. Echocardiography revealed a mitral valve mass for which she underwent surgical resection and mitral valve replacement. Histological examination of the mass revealed cavernous hemangioma of the mitral valve. Postoperative course was uncomplicated, and the patient's symptoms improved after surgery. Surgical excision of valvular hemangiomas appears to be curative in most cases and is the treatment of choice. Periodic echocardiographic follow-up is advised for early detection of tumor recurrence.
