Case 148: Decoding the Bicuspid Aortic Valve

A 60-years old diagnosed to have aortic stenosis came for evaluation of the aortal and LV.

We can also visualize the aortic valve itself in detail on CMR and characterize it.

To do that these are the steps

  1. Orient the transaxial cine so that the IAS is at 7 o'clock position
  2. Find out whether the valve is 3-sinus or 2-sinus
  3. Further subtype: If 3-sinus fused, which cusps are fused? If 2-sinus, what is the orientation?
  4. Assess the symmetry
  5. And obviously assess the aortopathy, for which the patient has come.

The definitive article that helps with answering these questions is the one published in 2021 headed by Hector Michelena.

The video below answers all these questions and provides a practical guide to assess the bicuspid aortic valve.
