Abstract

Various surgical methods are available for the management of anomalous aortic origin of the right coronary artery (AAORCA), preferably unroofing when the intramural segment can be identified.Hypoplasia of the proximal segment, an acute take-off angle, and close proximity to the intercoronary pillar or commissure are limitations to unroofing, and alternative approaches are more appropriate.Coronary artery bypass graft, with either arterial or venous graft, can be performed when unroofing and reimplantation are not feasible. Measuring the distal anastomosis flow may help with a decision regarding native coronary artery ligation. It remains undetermined whether arterial or venous grafts provide superior outcomes.
