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

Although all methods are associated with inaccuracies, echocardiographically determined PAPm was superior to the current guideline recommendation of using TR Vmax with regard to its correlation with invasively determined PAPm and the presence of PH. PAPm may be considered as an alternative to TR Vmax for evaluating the echocardiographic probability of PH.
