It is unknown whether the absence of a measurable TRV signiﬁes normal pulmonary artery pressure. Methods and Results-—We extracted hemodynamic, TTE, and clinical data from Vanderbilt’s deidentiﬁed electronic medical record WebThe 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 V max) 2 + RAP. cider in light bulb bottle
