Transthoracic echocardiogram to determine right ventricular systolic pressure (RVSP). (a) Continuous-wave Doppler measurement of peak tricuspid regurgitant velocity of 2.9 m/s. Right ventricular systolic pressure is calculated via the modified Bernoulli equation . A small inferior vena on expiration (b) that completely collapses on inspiration (c) consistent with a mean right atrial pressure of 5 mmHg.
