Angiographic demonstration of tumor vascularity in left atrial myxoma: a case report.

We describe a 63-year-old woman with a large sessile left atrial myxoma and coexisting mitral valve stenosis and regurgitation. The diagnosis of a left atrial tumor was confirmed by echocardiography and coronary angiography. This case reveals the rare finding of tumor vascularity originating from both the right coronary artery and left circumflex artery.
