In this video, Tommy will teach you how to evaluate a patient with low-flow, low-gradient aortic stenosis. This patient later underwent stress echocardiography. In patients with true aortic stenosis and reduced left ventricular function, the transvalvular gradient will increase whereas the valve area will remain unchanged. This patient's mean gradient increased to over 40 mmHg following dobutamine administration, which was indicative of significant stenosis. He was consequently transferred for surgery and is currently doing well. It can be really tricky to differentiate true- from pseudostenosis. Our online course will provide more information on the topic. If you register, we will let you know as soon as the full course is online.

You need to also put color doppler to know where to put your cursor to get the highest velocity and see where its aliasing.

That patient needs dopamine stress echo test to r/o pseudo-AS. Thanks for video Good JOB :)

The max velocity for AOV looks to be almost 3.5 m/s... doesn't the initial doppler you got for AOV show it could be at least moderate A.S.?

Excellent video, very much appreciate your time in making it.

The jet appears too fast. Wondering what was the calculated aortic valve area and the stroke volume. The issue is whether this is moderate or severe AS. You did not show us the VTI of the LVOT.

I guess its in the advanced course. He also didnt do pht, but the guy is clearly very good at echo/sono. wont be giving out advanced stuff for free I think

Prefer a book for echocardiogram

I've always been under the impression that a stress test has low sensitivity and specificity for ACS... what is the specific indication of the stress test in this situation? also, did u mean STresS ECG or Stress ECHO?

Stress Echo to see if that valve opens with better inotropism, if it opens it is a pseudo-AoS, if it doesnt open even with optimized contractility, it is a real AoS
