Abstract：
Cardiac myxoma is the most common primary benign cardiac tumors, mostly found in the left atrium. It was previously reported that the main component of myxoma was myxoid stroma riched in acid-mucopolysaccharide, the blood vessels in which were sparsely distributed, being characterized as hypovascular tumor by contrast echocardiography (CE) and computed tomography angiography (CTA). There are few reports of myxoma with rich blood supply and we report one in the left atrium.
