Right atrial pressure is not adequate to calculate portal pressure gradient in cirrhosis: a clinical-hemodynamic correlation study.


UNLABELLED Hepatic venous pressure gradient (HVPG), the difference between wedge and free hepatic venous pressure, is the preferred method for estimating portal pressure. However, it has been suggested that hepatic atrial pressure gradient (HAPG)--the gradient between wedge hepatic venous pressure and right atrial pressure (RAP)--might better reflect… (More)
