WebNov 25, 2024 · Of the remaining 221 patients, 118 patients had EF ≥50% and 103 patients had EF <50%. Regression analysis was performed for LA reservoir strain and TR velocity against LVFP. LA reservoir strain at a cut-off value of <18% was applied instead of TR velocity in the 2016 ASE/EACVI algorithm and compared with the current algorithm. 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.
