Case Report

A newborn presented with a murmur and cyanosis unresponsive to supplemental oxygen (O 2). Arterial blood gas obtained on a ¼-L nasal cannula O 2 with a fraction of inspired O 2 (FiO 2) of 100% showed partial pressure of arterial oxygen (PaO 2) of 40 mmHg. An echocardiogram demonstrated persistent truncus arteriosus, with the branch pulmonary arteries arising from the common arterial trunk and aortic arch interruption between the left common carotid artery (LCCA) and the left subclavian artery (LSA) (Van Praagh classification A4 [ 4], Fig.  1).
