Congenital abnormalities of the main pulmonary artery (MPA) and ascending aorta (AA) often necessitate surgical repair or the use of a valved conduit replacement, requiring multiple re-interventions due to regurgitation or failure of the prosthetic conduit. In recent years there has been a growing interest in the development of a living autologous tissue graft that could address the critical need for growing substitutes in the repair of congenital cardiovascular defects . Regardless of the particulars of the therapeutic approach, the detailed growth characteristics of the native artery is required to establish the baseline dimensional changes post-implantation. During normal embryogenesis the Truncus Arteriosus begins to split and form into the anterior pulmonary artery and the posterior aorta . Due to their common embryologic origin from a single outflow tract, there are disease conditions that originate in one artery and eventually affect both arteries . Therefore, the postnatal growth deformation of both the MPA and AA was computed to quantify the effects of the mechanical association of these two arteries.
