Aortic arch deceptively normal in long axis. On this static image, it almost appears as though the aortic arch is being demonstrated and appears to be of good size. In fact, the left subclavian artery is arising from the top of the ductal arch where it meets the diminutive aortic arch. The aortic arch is antegrade due to the flow coming into it from the apical ventricular septal defect (VSD). However, often, a diminutive aortic arch is difficult to trace out along its entire distance and multiple views and clues need to be used.
