1 A 58-year-old woman with aortic stenosis investigated by echocardiography and CT. (A) Doppler echocardiography demonstrating a peak aortic valve (AV) velocity of 3.6 m/s, a mean gradient of 27 mm Hg and an aortic valve area (AVA) of 0.8 cm2 based upon the continuity equation. A 58-year-old woman with aortic stenosis investigated by echocardiography and CT. (A) Doppler echocardiography demonstrating a peak aortic valve (AV) velocity of 3.6 m/s, a mean gradient of 27 mm Hg and an aortic valve area (AVA) of 0.8 cm2 based upon the continuity equation. (B) Non-contrast calcium scoring CT in the axial plane showing minimal aortic valve calcification (AV calcium score 37 AU). (C) Images from contrast-enhanced CT in the en face plane and (D) coronal plane revealing marked leaflet thickening with low attenuation signal suggestive of valve fibrosis. AO, aorta; AV, aortic valve; AVA, aortic valve areas; PG, pressure gradient; VTI, velocity time integral. Timothy R G Cartlidge et al.
