Anterior pulmonary translocation for repair of truncus arteriosus with interrupted arch

A newborn was found to have truncus arteriosus and an interrupted aortic arch, and underwent primary repair. The patient did well initially, but, by 8 weeks postoperatively, showed evidence of severe compression of the right pulmonary artery. At reoperation, the pulmonary artery was found to be compressed by a large aortic root (truncal root) and the retroaortic area was narrowed. The pulmonary artery bifurcation was therefore translocated anteriorly to alleviate the compression.
