Direct reimplantation as an alternative approach for treatment of anomalous aortic origin of the right coronary artery.

Anomalous aortic origin of the coronary artery (AAOCA) is a rare cardiac anomaly associated with myocardial ischemia, infarction, and even sudden death. We report 2 patients presenting with AAOCA of the right coronary artery originating from the left coronary sinus with an initial intramural course. In both patients, we performed uncomplicated direct reimplantation of the right coronary artery into the right coronary sinus. For this purpose, the right coronary artery was dissected from the transmural emersion point out of the aortic wall, subsequently as proximal as possible transected and directly reimplanted into the right coronary sinus. In both cases, the postoperative course was uneventful, and cardiac computed tomography confirmed excellent postoperative results after 1 year of follow-up. This technique is a convenient and easily performable approach, characterized by short cross-clamp times and avoidance of aortotomy, and thus is an excellent alternative strategy.
