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!
Mitral Valve Area by Deceleration Time (DT)
Calcs>Mitral Stenosis>MVA by DT>1
to get an MVA BY DT.
1: Obtain a PWD or a CWD of the mitral valve.
The flow profile of the mitral valve will have a Vmax,
typically the maximum velocity of the E wave.
The time from the Vmax to the where the velocity is
equal to zero is the deceleration time. Typically,
the curve will have to be extrapolated to the zero
velocity. The mitral valve area is equal to
759 divided by the deceleration time.
