A case report of a round cystic tumor in the left ventricular outflow tract. J Am Soc Echocardiogr. 2006 Nov;19(11):1402.e9-1402.e11.

We report a case of a patient who was admitted to our hospital complaining of angina pectoris. On auscultation, a systolic ejection murmur was heard at the right upper sternal border. Transthoracic echocardiography displayed regional wall motion abnormalities and detected a mobile mass in the left ventricular outflow tract, causing mild obstruction during systole. The mass appeared as an unilocular cystic tumor. Coronary angiography showed a significant lesion in the left anterior descending artery. Surgical treatment was indicated for coronary artery disease and for the unpredictable behaviour of the neoplasm. The mass was identified as arising from the top of the anterior papillary muscle. Histopathological examination revealed that the tumor was a cavernous hemangioma. Cardiac hemangiomas are rare, benign vascular tumors of the heart. This is an unusual case of left ventricular hemangioma incidentally discovered, which raised an interesting differential diagnosis.

Cardiac hemangioma of the right atrium. Eur J Echocardiogr. 2008 Jan;9(1):52-3.

Primary cardiac tumors are rare, with an incidence range between 0.001% and 0.030% at autopsy. Recent technical advances have facilitated diagnosis and surgical treatment of such lesions. Patients with a resectable tumor usually have a good prognosis, but patients with an unresectable tumor may have a poor prognosis. This report shows a case of right atrial hemangioma growing like an extracardiac mass, with cardiac tamponade the only clinical presentation.
