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...

How often have you found yourself “in over your head” in the abdomen when trying to image the IVC and abdominal aorta? Is imaging the abdominal aorta part of your echo protocol? It is not uncommon for a patient to receive an abdominal ultrasound because the echo findings mentioned the...

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...

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...

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). With echo being the gold-standard to evaluating and...
