Tricuspid regurgitation jet on colour Doppler echo

Tricuspid regurgitation jet seen on colour Doppler echocardiography from the apical four chamber view. RV right ventricle; LV left ventricle; LA left atrium; RA right atrium. The mosaic colour indicates high velocity with aliasing while the proximal most portion of the jet in right atrium is blue indicating flow away from the transducer. The tricuspid regurgitation in this case was moderate to severe. The right atrium and right ventricle are dilated due to pulmonary hypertension. Left atrium is also dilated due to mitral regurgitation.
