A 73-year-old man without a history of coronary artery disease had two episodes of significant ST-segment elevation indicative of inferior myocardial ischemia during the resection of an abdominal aortic aneurysm. During the further course, sudden ST-segment elevations occurred and resolved spontaneously without preceding hemodynamic instability. The patient sustained two episodes of cardiac arrest due to ventricular fibrillation and intermittent third-degree atrioventricular block with ventricular asystole. On cardiac catheterization, coronary arteries had a right dominant pattern. The right coronary artery was entirely patent on multiple injections. Thus, right coronary artery spasm is the only possible explanation for these observations.
