Adaptation of electron beam computed tomography (CT) coronary calcium scoring techniques have allowed CT quantification of aortic valve calcification. There is progressive awareness of the need for an imaging technique for this purpose. Following on from the recognition that modification of the traditional vascular risk factors (also associated with calcific aortic stenosis) may result in slowing of progression, or even regression of aortic valve lesions, an accurate and reproducible method for quantifying aortic valve calcification is required for follow up. Electron beam CT has been proposed to fulfil this role and to enable comparison of the postoperative calcification of different aortic valve bioprostheses. This review examines the current status of CT aortic valve imaging, and explores future directions.
