I just wanted to let you know that even though I'm looking quite old, I'm still a millenial.
So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks.
Don't worry, my wisdom won't change. You're still going to find the same useful information here. Stay tuned!
E-Echo will be continuing to be available after this year! A new company is taking over.
Aortic Valve Area by Planimetry

AVA = CuspLength2 x 0.433
to get an AVA by Planimetry.
1: Obtain a short axis view of the aortic valve
and either trace the circumference or measure the
length of one side. The optimal view is the MEAVSAX
view in a zoomed mode. The endothelial boarder
of the aortic valve leaflets should be sharp.
Scarring and calcifications can cause a blurry leaflet
boarder which can lead to errors. If the boarders
of the leaflets are visible then the aortic valve
area can be calculated utilizing the tracing function
on the echocardiographic machine. Alternatively,
one side of the aortic valve can be measured and the
aortic valve area can be calculated from the area
of a equilateral triangle. The preferred method
is to trace the aortic valve area rather than calculate
