Quantification of Tricuspid Regurgitation Echocardiography and right ventricular angiogram can quantify tricuspid regurgitation.
Echo Quantification
Trivial: Non sustained jet within lcm of the annular line with maximal jet area 5 per cent of the atrial area.
Mild: Sustained colour flaw jet with jet area 5-20 per cent of right atrium.
Moderate: Jet area 20-40 per cent.
Severe: Maximal jet area >40 per cent of right atrium, regurgitation to IVC and hepatic veins and flow reversal, in the pulmonary artery.
