AbstractAngiographic contrast material is generally considered a vasodilator, although in vitro experiments have documented a spasmogenic effect. In this report we describe a patient with exercise and rest angina who developed spasm of the right coronary artery immediately following left ventricular angiography. The patient was treated successfully with calcium channel blockers. This is the first reported case of left ventricular angiography‐induced coronary artery spasm.
