Estimated mean PA pressure(mPAP) and PVR by echocardiography

mPAP = (0.61x SPAP) + 2

Systolic PA pressure, mmHg

TR Vmax, m/s

RA pressure, mmHg

mPAP = 4(PR early peak velocity)² + RAP

PR peak velocity, m/s

RA pressure, mmHg

mPAP = 90 − (0.62*ATRVOT)

RVOT acceleration time, msec

mPAP = meanΔP + RAP

TR mean PG, mmHg

RA pressure, mmHg

mPAP = (2/3 x PAEDP) + (1/3 x PASP)

PAEDP, mmHg

PA end diastolic velocity, m/s

PASP, mmHg

TR Vmax, m/s

RA pressure, mmHg

PVR = 10 x ( TR peak velocity / RVOT VTI ) + 0.16

TR peak velocity, m/s

RVOT VTI, cm
