Tricuspid regurgitation jet – Doppler echocardiography

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. WebPatients with pulmonic stenosis were excluded. Pulsed-wave Doppler was used to measure pulmonary artery acceleration time (PAAT) and right ventricular ejection time. Continuous-wave Doppler was used to measure the peak velocity of TR (TR(Vmax)), and EPSPAP was calculated as 4 × TR(Vmax)(2) + 10 mm Hg (to account for right atrial pressure). iras ais software download
