ABSTRACT
The assessment of valvular heart disease is a strength of echocardiography and magnetic resonance imaging, because of their ability to assess anatomic and functional detail. Imaging with CT is limited secondary to the lower temporal resolution. Imaging of the aortic valve allows differentiation between normal tricuspid, bicuspid, and quatrocuspid aortic valve anatomy. CT can precisely describe the extent and location of valvular calcification, which correlates with severity of aortic stenosis. The differential diagnosis of aortic stenosis is flow obstruction in the left ventricular outflow tract caused by a sub-aortic membrane. Ebstein's anomaly describes the apical displacement of the tricuspid valve insertion towards the right ventricle.
