[An anomalous origin of the left coronary artery associated with a right coronary spasm as the cause of angina and presyncope].

We describe the rare association of angina at effort and presyncope in a young patient with an anomalous origin of left coronary artery and associated coronary spasm in the normal right coronary artery. The patient did well under calcium channel blocker therapy after seven years of follow-up, which is in contrast with the usual recommended management of these patients.
