Prosthetic Aortic Valve Stenosis

We recently reviewed a case during a local hospital quality improvement meeting that required us to assess whether or not there was prosthetic aortic valve stenosis.  It was interesting to touch up on the key parameters that should be assessed.  This week we will review the key points...

Aortic Stenosis and Mismatch Values

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,...

Aortic Stenosis Low Flow, Low Gradient: What’s the hype?!

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. The...

3 Additional Methods to Evaluating the AVA

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: AVA Planimetry Indexed Continuity...

Top 5 Factors to Consider when Evaluating for AS

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...
