The aortic valve annulus is a dynamic complex elliptical or ovoid 3D entity that is also subject to constant shape deformation across the cardiac cycle in addition to being influenced by the thoracic and intra-thoracic anatomy or variations. Given this inherent nature of the aortic valve annulus, electrocardiographic gated cardiac computed tomographic angiography (CCTA), a robust dynamic 3-dimensional imaging modality, is now widely accepted as the "gold-standard" for evaluating the aortic valve apparatus (AVA). To maximize the information obtained by CT, imaging needs to be performed with intravenous contrast injection.2 CCTA requires administration of iodinated contrast. The volume of iodinated contrast medium is of concern in many patients because candidates for TAVR frequently have impaired renal function.2 Contrast reduction and adherence to protocols for prevention of contrast-induced nephropathy is recommended.2 For access planning via the ilio-femoral route, some groups have reported direct aortic injection with extremely low volumes of contrast.
