ECHOCARDIOGRAPHIC ESTIMATION OF MEAN PULMONARY ARTERY PRESSURE: A COMPARISON OF DIFFERENT APPROACHES TO PREDICT PULMONARY HYPERTENSION

Background: Current guidelines advise the use of echocardiography to non-invasively estimate the likelihood of pulmonary hypertension (PH) in patients. The maximal tricuspid regurgitation velocity (TRVmax) is recommended as the main parameter to use in assessing the echocardiographic probability of
