Three-month-old male patient with poor feeding. ECHO revealed evidence of ASD, conotruncal septal defect, and single trunk overriding IVS and giving rise to aorta and pulmonary artery. ECG-gated multi-slice CT angiography of the heart and great vessels confirmed the presence of ASD and muscular VSD as well as the single trunk (truncus arteriosus) with wide root that is overriding the VSD and supplying the thoracic aorta and the pulmonary artery on oblique sagittal (a) and (b) MIP images. It also revealed that the aortic arch is right-sided with aberrant left subclavian artery, running posterior to the trachea, and esophagus on reformatted axial image (c), which was not detected by ECHO
