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 Pressure Half-Time (PHT)
Calcs>Mitral Stenosis>MVA by PHT>1
to get an MVA by PHT.
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 velocity equal to Vmax
divided by 1.4 is the pressure half time. (Vmax
/ 1.4 is equivalent to the half pressure). 220
divided by the PHT is the mitral valve area.
