to get an RVSV from Doppler.
1: Measure the RVOT diameter in centimeters.
The optimal view is the RVIO view. Caliper the
RVOT as close to the valve as possible, in mid systole.
2: Obtain a continuous wave doppler of the pulmonary
valve. The optimal view is the short axis of the
aortic arch. In this view the pulmonary valve
is in it's long axis and provides the best angle to
doppler the gradient's across the valve. An
alternative view is the deep transgastric view around
90 degrees. The pulmonic valve should be viewable
in most instances, however, the angle for the doppler
scan may be off more than 20 degrees. Once the
view is obtained turn on the CWD and use the track
ball to move the CWD line to the pulmonary valve.
A doppler profile of the pulmonary valve should be
displayed. Trace the flow profile with the trackball
and the VTI will be calculated.
