This is how a normal aortic bioprosthetic valve is showed on echo. This type of valve (which doesn’t need an INR between 2-3) is generally used in old people (with ~15 years of life expectancy or less) or special cases (such as pregnant women, unable to anticoag, etc.) that need a valve replacement because of senile aortic stenosis (most common), congenital abnormalities, endocarditis…

🎥1️⃣: This is a short axis TEE view of a normally functioning bioprosthetic aortic valve. Note the 3 struts from which the valve was constructed as well as the post surgical changes seen at the aortic root. This is the classic appearance of a typical bioprosthetic valve.

🎥2️⃣: Color doppler interrogation should be performed in all views to assess for valvular and paravalvular regurgitation. There appears to be trace central regurgitation in this view.

🎥3️⃣: A long axis view shown here shows normal opening and closing of the valve leaflets.

🎥4️⃣: The deep transgastric position at zero degrees can be used to assess for valve gradients by TEE. Here is a typical view. Color doppler shows there is some mild valvular regurgitation.
