Figure 1: Determination of pulmonary artery pressure using Doppler echocardiography. Using the modified Bernoulli equation the systolic PAP (=4[TR]2 + RA) can be calculated. Systolic PAP is equal to the right ventricular systolic pressure in the absence of pulmonary stenosis. In this case, estimated systolic PAP is 4 × (3.12)2 + 10 = 49 mmHg. (PAP: Pulmonary artery pressure, TR: Tricuspid regurgitation velocity, RA: Right atrial pressure)
