Introduction
Coronary artery anomalies are defined as those angiographic findings in which the number, origin, course, and termination of these arteries are rarely encountered in the general population. 1-3. An anomalous origin of the right coronary artery (RCA) from the left sinus is a very rare anomaly with incidence is 0.019% to 0.49% on coronary angiography. 4Accordingly, coronary artery anomalies are divided into those that cause and those that do not cause myocardial ischemia. Malignant features of anomalous coronaries include slit like ostium, an acute angle of takeoff, an intramural course, and significant compression between the aorta and the pulmonary trunk5.
