Computed tomography can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.[1]

CT Scan

Shown below is the plain CT of a patient with supravalvular aortic stenosis. The image shows an almost circular supravalvular aortic calcification of the aortic wall with extension of calcifications into the left main stem. The area of calcification is shown in yellow.


Following are a few advantages of the use of CT in Aortic Stenosis.[2]

  • CT scan provides additional anatomic details compared to echocardiography.
  • It may allow quantitattion of chamber sizes and calcification of the aortic valve.
  • The presence of calcification is a marker of hemodynamic severity, particularly in the younger patient.
  • It is done faster compared to MRI, thus avoiding the need for anesthesia in small children.


  • CT scan is costly.
  • Radiation can have long terms side-effect on growing children.

Class IIa
5.   In patients with suspected low-flow, low-gradient severe AS with normal or reduced LVEF (Stages D2 and D3), measurement of aortic valve calcium score by CT imaging is reasonable to further define severity.(Level of Evidence: B-NR)
