Pulmonary
regurgitation causes volume overloading of the right ventricle,
indicated on the echocardiogram by enlargement of the right ventricle
and reversal of septal motion, as described earlier for tricuspid
regurgitation following surgery for pulmonary stenosis. The combination
of residual right-sided hypertrophy with overfilling of the right
ventricle due to regurgitation gives a very deep pulmonary valve
a-dip, and may even open the valve fully before the onset of systole
(Fig. 59). Doppler, again, has been shown to be quite sensitive
in detecting and quantitating the severity of pulmonic regurgitation.
