Contralateral Unidirectional Cavopulmonary Shunt for Single Ventricle Palliation

Unidirectional cavo pulmonary shunt supplemented with systemic to pulmonary arterial shunt is often necessary for palliation of single ventricle with unilateral hypoplasia of a pulmonary artery. In rare instances, the adequately sized pulmonary artery is on the contralateral side as the superior caval vein making this anastomosis challenging. This report describes the operative technique involved in construction of the right superior caval vein to left pulmonary artery anastomosis.
