In the past, we have written articles on aortic stenosis and best practices for performing the continuity equation. It’s great to read blogs but it is important to apply this knowledge to our everyday practice. That is why this week we asked experienced sonograher, Jessica Hooley, ACS, RCS, to share some real life examples of aortic stenosis and mismatch values and provide us with some tips and recommendations.
We’ve all been in this situation…. our patient appears to have a very tight, calcified aortic valve which visually appears to be moderate to severe aortic stenosis. As we scan through our protocol, we obtain a peak aortic valve velocity of 3.3 m/s and mean pressure gradient (PG) of 23.6 mmHg.
Last week we broke down the continuity equation to evaluate the severity of aortic stenosis. This week, we are going to discuss other methods that can be used to evaluate the severity of aortic stenosis. This blog will cover the following methods:
Last week we broke down the methodology of the continuity equation to calculate the aortic valve area (AVA). If you missed it, you can find it HERE. The ASE guideline recommends using the continuity equation calculated AVA, peak aortic jet velocity and mean pressure gradient to evaluate and determine the severity of aortic stenosis (AS) present.
