A 67-year-old man develops sudden pain and coldness in his right hand 12 days after an anterior myocardial infarction. The brachial pulse is present, but the radial and ulnar pulses are absent. Echocardiography shows an adherent mass in the akinetic left ventricular apex. Angiography shows an abrupt brachial artery bifurcation cutoff with little atherosclerosis in the surrounding arterial wall.
