Abstract

To study the clinicopathologic features of primary cardiac valve tumors. Eleven cases of primary valve tumors collected from Fuwai Hospital during the period from 1983 to 2005 were enrolled into the study. The tumors were stained with hematoxylin and eosin and Weigert-Van Gieson stain. Immunohistochemistry was also carried out in selected examples. Primary cardiac valve tumors were uncommon and accounted for only 3% (11/426) of all primary cardiac tumors. Most of them (10/11) were benign and malignancy was rarely encountered (1/11). The tumor subtypes included papillary fibroelastoma (4/11), cavernous hemangioma (4/11), glomus tumor (1/11), angiosarcoma (1/11) and hamartoma (1/11). Of the 11 tumors studied, 4 involved the tricuspid valve, 4 involved the mitral valve, 2 involved the pulmonary valve and 1 involved the aortic valve. The diagnosis was established by preoperative echocardiography in 7 patients. The remaining 4 cases were either misdiagnosed or undiagnosed. Preoperative diagnosis of primary cardiac valve tumors can be difficult due to lack of detailed information related to this group of lesions. Although benign cardiac valve tumors carry a good prognosis, the clinical outcome may be disastrous as a result of hemodyn...Continue Reading

Cavernous Hemangioma

Cavernous hemangioma is a blood vessel defect or benign tumor that leads to leakage of blood to the surrounding tissues. This can occur in several organs including the brain, which can lead to seizures. Discover the latest research on cavernous hemangiomas here.
