Tricuspid Valve Area by PHT
Calcs>Tricuspid Stenosis>TVA by PHT>1
to get an TVA BY PHT.
1: Obtain a PWD or a CWD of the tricuspid valve.
The flow profile of the tricuspid 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). 190
divided by the PHT is the tricuspid valve area.
