title: Coronary arteries from a single coronary ostium in the right coronary sinus: a previously unreported anatomy.
abstract: The coronary circulation originating from a single coronary ostium is rare. All possible anatomical variations were the basis of a recent classification. This case report describes a previously unreported IID(1) pattern, comprising a solitary coronary ostium in the right coronary sinus with an anatomical course of the right coronary artery. The left circumflex coronary artery arises from the proximal right coronary artery coursing behind the aorta to the left. The left anterior descending coronary artery arises from the proximal right coronary artery coursing to the left side anterior to the right ventricle.
