Resolution of ischemia with β-blocker in a patient with anomalous right coronary artery.

Anomalous origin of right coronary artery (RCA) has been associated with angina, myocardial infarction and sudden death. Often these patients are referred for surgery. However, long-term β-blocker therapy instead of surgery has been used in some cases with success. The authors report a case of anomalous RCA where resolution of ischemia with β-blocker was objectively demonstrated on serial stress testing.
