Primary hemangioma of the mitral valve: an unusual presentation.

Abstract

Cardiac hemangiomas are rare tumors, the presence of these neoplasms in heart valves is an exceptional finding, mainly because of their histological features. Normally, transesophageal echocardiography is used to establish a diagnosis of cardiac tumor, though careful interpretation is needed to avoid diagnostic errors. Herein is described an unusual presentation of a primary hemangioma of the mitral valve which was diagnosed as a prolapsing left atrial myxoma. The patient underwent successful surgical excision of the neoplasm, followed by mitral valve repair.
