Echocardiogram: (a) The apical 4-chamber view of the heart. The right ventricle (RV) is mildly dilated. A blue color Doppler signal representing tricuspid regurgitation is shown. (b) A continuous wave Doppler of the tricuspid regurgitation jet. The peak velocity of the tricuspid regurgitation jet is used to estimate pulmonary artery systolic pressure (approximately 50 mmHg in this example).
