Truncus arteriosus (TA) with interrupted aortic arch (IAA) is a rare congenital cardiac anomaly. Traditionally, IAA would require period of deep hypothermic circulatory arrest (DHCA) for aortic arch reconstruction. DHCA may cause myocardial depression and neuro-developmental dysfunction. IAA repair is presently being performed with hypothermic low-flow selective cerebral perfusion and distal body circulatory arrest. Even though this prevents cerebral adverse effects of DHCA, there is still risk to the spinal cord and kidneys.

Here, we describe the aortic arch reconstruction by maintaining the total body perfusion without any periods of circulatory arrest in a neonate with TA with IAA.
