Right coronary artery
- large ostium for the main right coronary artery
- small ostium for an infundibular branch
The right coronary artery courses in the right atrioventricular groove to the inferior surface of the heart, and then (in right dominant configuration) turns anteriorly as the inferior interventricular artery. In left dominant hearts this branch arises from the left circumflex artery.
