TR Colour Jet
Colour Doppler echocardiogram in apical four chamber view (slightly tilted) showing tricuspid regurgitation jet. Right ventricle (RV) is seen dilated and hypertrophied, with a prominent moderator band (just below the RV label). Right atrium (RA) is also dilated, both due to severe pulmonary hypertension (below). LV: left ventricle; LA: left atrium
TR JET - severe PAH
Tricuspid regurgitation (TR) jet documented by Doppler echo with peak gradient of 77.3 mm Hg, suggesting severe pulmonary arterial hypertension (PAH). Doppler line is seen across the right ventricle and atrium in the upper panel with sampling in the region of the tricuspid valve. The right ventricular pressure is estimated by adding the expected right atrial pressure from the observed jugular venous pressure to the peak TR gradient.
TR MILD PAH
TR jet in a case with mild PAH with gradient of only 21.7 mm Hg. The jet envelope is incomplete, indicating mild TR.
