We report a modification of the Norwood stage I procedure in a neonate with right aortic arch and complete atrio-ventricular canal in a variant of hypoplastic heart syndrome. Because of the unusual anatomy, the neo-aorta was reconstructed with a specially trimmed homograft patch and the pulmonary flow was maintained with implantation of a right ventricle to pulmonary artery shunt on the left side of the aorta. The patient had a favourable outcome and is now awaiting the stage II procedure.
