  		Figure 1 Tricuspid Regurgitation Gradient

On color flow Doppler signal, the highest tricuspid regurgitation gradient from parasternal, apical, or subcostal views is recorded. The apical view is shown.

  		Figure 2 End-Diastolic Pulmonary Regurgitation Gradient

On color Doppler signal from the parasternal short axis, the end-diastolic pulmonary regurgitation gradient is measured at the first peak deflection of the QRS on electrocardiogram, corresponding with termination of reverse flow across the pulmonic valve.

  		Figure 3 Percent Hospitalization for HF or CV Death by Elevations in EDPR or TR Gradients

Percent of patients with the combined outcome (heart failure [HF] hospitalization or cardiovascular [CV] death) by elevations in end-diastolic pulmonary regurgitation (EDPR) or tricuspid regurgitation (TR) gradients.
