Neovascularization of floating myxoma clearly depicted on angiograms

Although myxoma is a rare benign tumor, it is the most common benign tumor of the heart. It is predominantly observed in the left atrium (LA). A 38-year-old male patient was admitted to our clinic with exertional dyspnea. Transthoracic echocardiogram revealed a mass in the LA, and transesophageal echocardiogram confirmed a 16- x 17-mm sized, spherical-shaped mass in the LA (Fig. 1, Video 1). The patient had history of diabetes mellitus and hyperlipidemia. He underwent coronary angiography to exclude coronary artery disease. Coronary arteries were observed to be normal. However, angiography showed that the myxoma was opacified with contrast. The myxoma was neovascularized with the distal circumflex artery. The vascular blush of the tumor was clearly indicated on coronary visualization (Fig. 2, Video 2, 3). The mass was histopathologically proven to be a myxoma (Fig. 3, 4).
