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!
Left Atrial Pressure by Color M Mode (CMM)
Calcs>Pressure>LAP by CMM>1
LAP = 5.27 x (E/Vp) + 4.6
to calculate a LAP using Color M-Mode.
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 Color M-Mode scan of the left ventricle.
Obtain a color flow doppler of the left ventricle
in the midesophageal view. While in color mode,
add the M-Mode mode to the scan and place the scan
line down the center of the left ventricle.
On the Color M-Mode scan the propagation of flow shows
an early passive filling (E wave) and late active
filling (A wave) of the left ventricle. Using
the caliper function measure the slope of the first
aliasing velocity of the E wave. Enter the slope
(Vp) or velocity of propagation.
