title: Arteriographic demonstration of spontaneous right coronary artery spasm in a patient with Prinzmetal's angina.
abstract: Coronary artery spasm may occur spontaneously during coronary angiography in patients with clinically documented or suspected Prinzmetal's angina. In other patients with Prinzmetal's angina, the spasm can be provoked by the administration of ergonovine. A patient with spontaneous spasm of the right coronary artery during coronary angiography is reported and some considerations for diagnosis and therapy of this entity is offered. Although intraoperative spasm has been reported in the cardiology literature, no such case has been described in the radiology literature.
