Hypoplastic aortic arch is a congenital heart defect that is prejudicial for the growth of newborns. It is often associated to other heart defects. Different surgical techniques exist to address this defect, but the literature is very poor with regards to the use of an autologous pericardial patch. Most use extensive dissection techniques or synthetic patches. Here investigators report institution's original approach using the newborns own pericardium for what investigators believe to be an optimal correction of the hypoplasia., with preserved growth potential.
