# Right Ventricular Systolic Pressure (RVSP) Calculator

Determines the Right Ventricular Systolic Pressure based on the TR jet maximum velocity by spectral Doppler to evaluate stenosis.

Refer to the text below the tool for more information about the RVSP and its normal range values.

The Right ventricular systolic pressure (RVSP) may be used in the evaluation of pulmonary valve stenosis. It is based on measuring the TR jet maximum velocity by continuous wave (CW) spectral Doppler.

If there is no significant stenosis then the RVSP may be equivalent to the systolic pulmonary artery pressure (SPAP).

`RVSP = 4 x (TR Vmax)2 + RAP`

Where:

• TR Vmax = TR Max Jet Velocity in m/s;
• RAP = Right Atrial Pressure (3, 8 or 15 mmHg or other value);
• RVSP = Right Ventricular Systolic Pressure in mmHg.

### RVSP Interpretaion by Age Group

## Right Ventricular Systolic Pressure Explained

The right ventricular systolic pressure (RVSP) may be used in the evaluation of pulmonary valve stenosis. It is based on measuring the TR jet maximum velocity by continuous wave (CW) spectral Doppler.

If there is no significant stenosis then the RVSP may be equivalent to the systolic pulmonary artery pressure (SPAP).

• `RVSP = 4 x (TR Vmax)2 + RAP`

Where:

• TR Vmax = TR Max Jet Velocity in m/s;
• RAP = Right Atrial Pressure (3, 8 or 15 mmHg or other value);
• RVSP = Right Ventricular Systolic Pressure in mmHg.

RVSP may be interpreted by age group as follows:

 Age group RVSP normal range (mmHg) <50 years 16 - 39 50 - 75 years 15 - 45 >75 years 17 - 52

Right atrial pressure may be elevated due to restrictive filling, tricuspid E/E’>6 or diastolic flow predominance in hepatic vein.
