Reconstruction of the aortic arch for the Norwood procedure remains a focus of attention in terms of the management of the distal anastomosis [1,2], patch design and material [3,4], and fashioning the Damus-Kaye-Stansel itself [5]. The reconstructed aorta supplies the coronaries and the head and neck vessels and directs flow to the descending aorta. As the fetus develops, the right ventricle shunts to the aorta through the ductal arch, supporting a great percentage of the systemic and the placental circulation. We have developed a method of designing a Norwood patch by decoding the 3-dimensional geometry of the arterial duct and its arch.
