Unroofing aortic intramural left coronary artery arising from right pulmonary artery.

We report an operative case of the anomalous origin of the left coronary artery from the right pulmonary artery with aortic intramural course. This particular anatomy was clearly identified with a preoperative angiogram. The restoration of the two-coronary system was accomplished by unroofing the intramural segment into the left sinus of Valsalva with encouraging midterm results. The details of this anatomical correction are described with a review of the literature.
