An alternative echocardiographic method to estimate mean pulmonary artery pressure: diagnostic and clinical implications.

Background: The aim of this study was to evaluated an alternative echocardiographic method to calculate mean pulmonary arterial pressure (MPAP).

Methods: One hundred two patients were studied with simultaneous right-heart catheterization (RHC) and echocardiography. MPAP was calculated by adding the right ventricular-right atrial mean systolic gradient to right atrial pressure.
