From: Journey of a patient with chronic thromboembolic pulmonary hypertension
Serial echocardiographic observations of tricuspid regurgitant jet (continuous-wave Doppler recording). Note the pseudo-normal trans-tricuspid pressure gradient (19 mmHg) with the pathological late-peaking velocity spectrum at the final examination (August 2013), clearly distinct from the normal pressure gradient exhibiting an early-peaking velocity spectrum at the examination in 2007, that is, prior to the clinical event of pulmonary thromboembolism.
