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!
Pulmonary Capillary Wedge Pressure by Tissue Doppler Echo
PCWP = 1.55 + 1.47(Emax/Emax')
to calculate a PCWP by TDI.
1: Obtain a PWD of the long axis view of the mitral
valve. The PWD will yield a E and A wave.
The maximum E wave velocity, Emax should be measured
and entered above.
Step 2: Obtain
a TDI scan of the mitral valve. A TDI
scan of the mitral valve is a tissue color mode scan
with pulse wave doppler of the mitral valve annulus.
After initiating the scan a velocity profile will
be exhibited that is similar to the PWD of the LVI.
An early velocity peak, the E´
and a late velocity peak, the A´
are present. The maximum velocity of the E´
velocity profile is the Emax´.
