1: Obtain a CWD of the long axis view of the tricuspid
valve. Tricuspid regurgitation must be present
to make this calculation. Tricuspid regurgitation
is present in most normal individuals so this calculation
should be able to be made in almost everyone.
A CWD of the TR jet will yield a peak velocity.
Four times the square of the peak velocity of the
TR jet yields the gradient across the valve during
ventricular systole. The gradient added to the
CVP will yield the RVSP or PASP (in no RVOT outlet
obstruction is present).
