Pulmonary hypertension is a harbinger of bad outcomes in patients with cardiovascular disease and in patients with pulmonary diseases. Echocardiography plays a key role in the initial evaluation of patients with pulmonary hypertension, and in evaluating response to treatment. In patients with advanced disease, the right ventricle (RV) and the right atrium (RA) are dilated, and there are several indicators of increased pulmonary artery pressure including increased peak velocity of tricuspid regurgitation (TR), peak velocity of pulmonary regurgitation (PR), and also increased end-diastolic PR velocity. Despite the availability of many indices of increased pulmonary artery pressures, there are diagnostic challenges in some patients and there is a need for achieving higher accuracy, thus the need for ongoing research efforts in this field.
