Single coronary arteries (SCAs) constitute a rare coronary anomaly which is usually asymptomatic. However, SCAs may become symptomatic and even cause myocardial ischemia and infarction and as such necessitate proper intervention whether percutaneous or surgical. We describe an 89-year-old woman with an SCA from the right sinus of Valsalva presenting with chest pain and acute myocardial infarction. We succeeded in performing percutaneous coronary intervention and stenting on the ostial lesion of the SCA, and there were no further complications. The patient was discharged 2 days later with no adverse complications.
