title: Coronary artery spasm as a cause of chest pain in a patient with anomalous origin of the right coronary artery from the left sinus of valsalva.
abstract: The cause of chest pain in patients with anomalous origin of the right coronary artery from the left sinus of Valsalva has not yet been elucidated. In the following case, this anomaly was demonstrated, upon angiography, in a patient with recurrent chest pain and a negative stress test; in addition, spasm of the left anterior descending coronary artery was documented during ergonovine provocation. To our knowledge, this is the first time coronary artery spasm has been documented in a patient with this anomaly. On the basis of this case, we recommend ergonovine testing for all angina patients with aberrant coronary arteries in whom no other cause of chest pain is found at cardiac catheterization.
