Figure 3. Moderate aortic valve stenosis in a 73-year-old patient. Double-oblique reconstruction of contrast-enhanced retrospectively ECG-gated multi-detector row CT data set demonstrates a mildly calcified tricuspid aortic valve (grade 2, small isolated spots of calcification; large arrow). Image quality was rated as poor (grade 2, poor visibility of the anatomic details of the aortic valve). The aortic valve leaflets can be appreciated (small arrows), but the free edges of the aortic valve leaflets (black arrowhead) and the aortic valve annulus (white arrowheads) are blurred.
