Aortic valve replacement. Coloured computed tomography (CT) scans through the heart of a 60-year-old man with heart failure due to valvular heart disease. His aortic valve (white) has been replaced. The views show the valve from three different angles. This artificial valve is a Medtronic-Hall valve, consisting of a pyrolytic carbon disc oscillating around an eccentric axis inside a ring. The aortic valve lies between the heart's left ventricle and the aorta. Here, it is in its closed (diastolic) position.
