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 peak pressure during right
ventricular systole. The RVSP will equal the PASP if
pulmonary stenosis or a RVOT outlet obstruction is absent.
