Tetralogy of Fallot

Commentary: On the road toward routine use of 3-dimensional techniques in complex congenital surgery

“…The goal of a successful repair in patients with tetralogy of Fallot, pulmonary atresia, and multiple aortopulmonary collateral arteries (MAPCAs) is to provide flow to the greatest number of lung segments. 1 It is therefore fundamental for the surgeon to understand the relationship of the collateral vessels to other mediastinal structures, such as the trachea and esophagus, to plan the best surgical approach. Three-dimensional (3D) printing and visualization techniques are emerging as potentially valuable tools to inform the management of patients with MAPCAs, allowing reconstruction of 3D anatomic relationships from imaging data.…”
