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.
