The application of NO close to the endotracheal tube is associated with a much faster response of the actual inspired NO concentration to dosing changes and shows the lowest NO2 formation. In order to avoid toxic NO2 concentrations, an upper limit of 40 ppm NO is recommended for continuous NO inhalation.

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.
