After the first successful repair of an AV canal defect by C. Walton Lillehei in 1955, there have been tremendous improvements in both surgical techniques and perioperative care of patients. Nowadays early mortality after surgical repair has dropped to less 3 to 4 % in many parts of the world. On the other hand, in terms of complexity, the repair of an AV canal defect could be quite challenging for surgeons in some cases. When we look at Aristotle scoring system which grades congenital cardiac procedures with regard to their complexity (simple: 1.5 to very complex: 15), surgical repair of an complete AV canal has been still classified as a comlex procedure (Aristotle score 9) [1]. Therefore, in this paper we try to summarize current surgical techniques used for repair of this complex pathology.
