Abstract

Hemangioma in heart chambers is rare, most cases with heat hemangioma without symptom. The case we presented was an extremely left ventricle hemangioma with hest pain and palpitation after exercise. The tumor was resected under cardiopulmonary bypass, histopathological analysis concluded a benign vascular tumor. Examination of the tumor revealed vascular proliferation and mucoid degeneration in matrix. Immunohistochemistry showed strong positive staining with antibodies against CD31 and CD34, which supported the vascular origin of this tumor.
