The authors present the case of a 59-year-old man with a medical history of dilated cardiomyopathy and heart transplantation 10 years prior following aortic valve replacement and simultaneous implantation of a left ventricular assist device (LVAD). At the time of the transplant, the donor heart had a bicuspid valve and normal aortic diameters. During the follow-up CT angiography, the patient was diagnosed with a 55 mm aortic root aneurysm, with a normal ascending aorta and aortic arch.

Pediatric patients are very heterogeneous, showing significant variations in weight and vessel dimensions.
