The role of Fontan's procedure and aortic translocation in the surgical management of patients with discordant atrioventricular connections, interventricular communication, and pulmonary stenosis or atresia

A variety of surgical strategies have been utilized in attempts to accomplish long-term haemodynamic stability in patients with cardiac anomalies characterized by discordant atrioventricular connections, ventricular septal defect, and severe sub-pulmonary obstruction. The majority of these patients have what is commonly referred to as congenitally corrected transposition, together with a ventricular septal defect and pulmonary stenosis or atresia, in the setting of either usual or mirror imaged arrangement of the atrial chambers and the other organs of the body. A smaller sub-group, with discordant atrioventricular connections and double outlet right ventricle, with severe sub-pulmonary obstruction or pulmonary atresia, present similar physiology, and a comparable surgical challenge.
