The four chamber view from a 2-D echocardiogram with color flow Doppler shows tricuspid regurgitation. The regurgitant "jet" is directed toward the posterior wall of the right atrium which is enlarged. There is also a high velocity, turbulent, and narrow echo into the right ventricle during diastole suggesting the presence of tricuspid stenosis.
