Pulmonary hypertension (PH) is a progressive disease characterized by increased pulmonary vascular resistance that leads to right ventricular (RV) failure, a condition that determines its prognosis. This review focuses on the clinical value of the evaluation of RV function in PH. First, the pathophysiology of PH, including hemodynamics, RV function, and their interaction (known as ventriculoarterial coupling), are summarized. Next, non-invasive imaging modalities and the parameters of RV function, mainly assessed by echocardiography, are reviewed. Finally, the clinical impacts of RV function in PH are described. This review will compare the techniques that yield comprehensive information on RV function and their roles in the assessment of PH.
