Background: Single Coronary Artery (SCA) is a rare, most commonly asymptomatic, congenital anomaly which is usually discovered incidentally during investigations. This entity consists of a single coronary artery supplying the entire myocardium. It may be classified based on the origin and the course of the artery. Depending on the patient's presentation and its severity, medical or invasive interventions may be warranted.
Case Report: A 65-year-old female patient known to have diabetes and hypertension presented to our emergency department with chest pain and discomfort. Blood tests and electrocardiography (ECG) showed no significant abnormalities, but on coronary angiography, we suspected an anatomical variation. Computed tomography angiography (CTA) confirmed our suspicion revealing a single coronary artery supplying the entire myocardium and arising from the right sinus of Valsalva. The patient received medical therapy and was discharged home.
Conclusion: We presented this case of Single Coronary Artery due to the rarity of this diagnosis. Presentation, treatment plan, and prognosis typically vary depending on the subtype of the anomaly. Early recognition is very important, especially in young adults.
