Aortic valve replacement. Coloured 2D (left) and 3D (right) computed tomography (CT) scans of a replacement aortic valve in the heart of a 58-year-old woman who was being treated for cardiac insufficiency. The aortic valve is shown both in its open (systolic) position (across bottom) and in its closed (diastolic) position (across top). 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. | |
