Values are mean (SEM).

PPHTN, portopulmonary hypertension; CO, cardiac output; SVR, systemic vascular resistance; mRAP, mean right atrial pressure; mRVP, mean right ventricular pressure; IVC, inferior vena cava.

***p<0.001, PPHTN versus no PPHTN.

n=52 for the no PPHTN group and n=10 for the PPHTN group unless otherwise stated
