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.

The evaluation and screening of aortic stenosis is a routine calculation performed on all complete echocardiograms. The detailed evaluation involves multiple key parameters that make up the equation that determines the aortic valve area (AVA).

Before harmonic imaging, our imaging transducers had major limitations when it came to obtaining high-velocity gradients with continuous-waved (CW) Doppler. Two of the main restrictions included the ultrasound frequency (no ability to drop down to a lower frequency) and the large footprint of the transducer.

Evaluating the aortic valve is a routine part of an echocardiogram. There are many methods we use to determine the structure and function of the valve, including 2D, color Doppler and a combination of pulsed & continuous-wave Doppler. With short examination times being a common challenge,

In our last post we reviewed the correct techniques for the linear measurement of the LV in the parasternal long axis view. This week we will discuss the aorta and review the morphology and the correct aortic measurement techniques to perform during an echocardiogram.
