Yock and Popp determined the right ventricular systolic pressure of a patient with tricuspid regurgitation using Doppler ultrasonography. The authors are from Stanford University.
Patient selection: tricuspid regurgitation
Parameters:
(1) maximum velocity of the regurgitant jet through the tricuspid valve during systole in meters per second
(2) mean right atrial pressure (approximated by the jugular venous pressure)
systolic pressure gradient between right ventricle and right atrium =
