CT angiography (CTA) of aortic regurgitation, the backflow of blood into the left ventricle of the heart, due to a defective aortic valve. The valve (centre) has been damaged due to atheroma, a build up of fatty plaque deposits. CT angiography uses mutliple X-rays to build up a picture of internal structures, combined with the presence of a contrast medium opaque to X-rays in the blood, allowing vessels to be imaged.
