A newborn baby, weighing 3 kg, with syndromic facies was referred to the hospital due to a prenatal diagnosis of a complete atrioventricular septal defect and a pulmonary atresia discovered during a fetal echocardiography. A physical examination revealed a continuous heart murmur at the left and right upper sternal border and a systolic murmur at the left lower sternal border. A blood oxygen saturation test in room air resulted in a saturation level of 93%. Since the anatomy and the source of the pulmonary blood flow were unclear, a cardiac CT examination was requested for pre-operative assessment.
