Pulmonary artery pressure Flashcards
PAP estimated from what measurements?
Tricuspid regurgitation jet velocity + estimated RA pressure 
TRmax velocity + RAP (from IVC)
Three signs of pulmonary hypertension.
- elevated PA pressure (normal <20)
– short time to peak velocity in PA velocity curve
– paradoxical septal motion (short axis views)
– high, end-diastolic pulmonic regurgitation velocity. 
Flying W
M mode mid systolic notching of posterior pulmonary valve cusp
Equals pulmonary hypertension
Pulmonary hypertension findings
- flying W
– RV chamber enlargement with flattening of IVS
– RV hypertrophy/systolic dysfunction.
– 
Pulmonary systolic pressure a.k.a.…
RV pressure.
PAP = 4(VTRpeak)2
When is RV pressure not the same as pulmonary systolic pressure?
When pulmonary stenosis is present, subtract RV-PA gradient 
When is wall thickness measured?
And where?
At end diastole, PLAX
– at level of MV chordae
– septum
– posterior wall
When is end diastole measured?
At the onset of the QRS
When is end systole measured?
Just before aortic valve closure… A.k.a.…
Minimum chamber size
What views are used to calculate 2D biplane EF?
Which wall is missed?
Apical 4C
Apical 2C
Inferior/lateral wall.

Apical long axis, a.k.a.…
3C apical view
