Extensive angiographically visible tumor vascularization was detected in a 71-year-old woman with a large left atrial myxoma. The patient suffered from paroxysmal dyspnea due to obstruction of the left ventricular inflow tract. The diagnosis was based on two-dimensional echocardiographic findings (Fig A; Ao = ascending aorta; Tm = myxoma) and was confirmed by pathologic examination. Transseptal resection of the myxoma arising from the interatrial septum was performed. Right anterior oblique view of the coronary angiogram shows clusters of new vessels (arrowheads) which originate from the atrial branches of the right coronary artery (RCA; Fig B) and from the circumflex coronary artery (RCX; Fig C).
