Anomalous origin of the coronary artery from the opposite sinus may have a potential for life-threatening presentation including myocardial infarction, arrhythmia, or sudden death. Surgery is generally indicated when the course of anomalous artery is interarterial between the aortic root and right ventricular outflow tract/pulmonary artery. Specific morphologic details, mainly the ostial status and intramural course, influence the type of surgical repair. The unroofing procedure is a technique suitable for those with intramural course, and it creates a new coronary ostium in the correct valsalva sinus, thereby eliminating the course between the pulmonary artery and aorta as well as the intramural course.
