Systemic-to-pulmonary arterial shunts
These procedures are required most frequently in those with right isomerism. Over time, descriptions have been provided of the use of the modified Blalock-Taussig shunt, the Waterston-Cooley shunt, and the UKC shunt.14-25,39,40 Construction of such shunts is usually followed by repair of totally anomalous pulmonary venous connection, with a superior cavopulmonary connection added for those requiring emergency intervention in the setting of a functionally univentricular heart.14-25,39-41 Alternatively, the shunt can be performed concomitantly with rechanneling of the totally anomalous pulmonary venous return.15,18,41 Others have delayed the repair of obstructed totally anomalous pulmonary venous connection by inserting a hybrid stent.22
