Combined Norwood and Rastelli procedure for repair of interrupted aortic arch with subaortic stenosis.

A neonate presented with an interrupted aortic arch type B and VSD with dysplastic aortic valve, subaortic stenosis, and aberrant right subclavian artery. We performed a direct anastomosis between the hypoplastic ascending aorta (0 3 mm), the main pulmonary artery and the descending aorta, mimicking a Norwood-type ventricular outlet. The right-ventricular outflow tract was reconstructed with a 8mm PTFE vascular graft. This combination of a modified Norwood with a Rastelli procedure facilitated establishment of a sufficiently large left-ventricular outflow tract via VSD, at the same time maintaining a biventricular system despite the coexisting anomalies.
