3D multiplanar reformat and color volume rendered MUSIC images of a 20-day old neonate (2.1 kg) with interrupted ascending aorta (a, bird’s eye view, Asc Ao) and ventricular septal defect (VSD, b) are shown. 4D color volume rendered MUSIC images are available as Additional file 3: Online video 5a. Relationships between the large main pulmonary artery (MPA), hypoplastic ascending aorta (3.8 mm), ductal arch, and intracardiac structures are depicted in c and d). Their 4D dynamic relationships are exemplified in Additional file 3: Online video 5a. The proximal course of the left coronary artery (LCA) is well visualized (c). FE-MUSIC CMR was obtained to clarify extra-cardiac vessels and intra-cardiac anatomy. Her heart rate ranged between 137 and 184 beats per minute. Clear definition of intra-cardiac anatomy along with findings of predominant flow through the VSD (e, Additional file 3: Online video 5b-c) resulted in the patient undergoing biventricular rather than single ventricle repair. LA, left atrium; LSA, left subclavian artery; LV, left ventricle; RSA, right subclavian artery
