Echocardiographic Estimation of Mean Pulmonary Artery Pressure: A Comparison of Different Approaches to Assign the Likelihood of Pulmonary Hypertension

•This study challenges the current preference for TR Vmax for estimating the probability of PH in the guidelines. •Estimation of PAPm by adding RAP to TR maximal right atrial–right ventricular gradient (by tracing the TR time-velocity integral) resulted in the best correlation with invasively measured PAPm. •Compared with several other algorithms, this method was also associated with the highest OR with regard to the prediction of PH....
