The correlation in echocardiogram to right heart catheterization in identifying pulmonary hypertension as a barrier to liver transplantation.

Background: Pulmonary hypertension (PH) and portopulmonary hypertension (POPH) can be limitations towards listing for liver transplantation (LT). Our study evaluates the correlation of right ventricular systolic pressure (RVSP) and mean pulmonary artery pressure (mPAP) on transthoracic echocardiogram (TTE) compared to mPAP on right heart catheterization (RHC).

Methods: We performed a retrospective review of 723 patients who underwent LT evaluation at our institution between 2012 and 2020.
