description: "Origin of the right coronary artery (RCA) from the left sinus of Valsalva or of the left main (LM) or left anterior descending (LAD) coronary artery from the right sinus of Valsalva, with the additional feature that the artery passes between the two great arteries. This carries a risk of the artery being compressed by these two vessels,"
