Initial gated non-cardiac computed tomographic angiogram. A gated non-cardiac axial contrast-enhanced computed tomographic scan of the sinuses of Valsalva is shown. Aortic motion artefact blurs the aortic wall anteriorly and posteriorly (arrowheads). This is the plane of aortic translocation during the cardiac cycle. The lines within the sinuses (arrows) were misinterpreted as aortic valve leaflets but lie above the cranial limit of normal leaflet tips.
