Haemodynamic changes in cirrhosis following terlipressin and induction of sepsis —a preclinical study using caval subtraction phase-contrast and cardiac MRI

ConclusionsCaval subtraction PCMRI and cardiac MRI in a rodent model of cirrhosis demonstrate significant baseline hepatic haemodynamic/cardiac differences, failure of the HA buffer response post-terlipressin and an altered HA fraction response in sepsis, informing potential translation to ACLF patients.Key PointsCaval subtraction phase-contrast and cardiac MRI demonstrate:• Significant differences between cirrhotic/non-cirrhotic rodent hepatic blood flow and cardiac systolic function at baseline.• Failure of the hepatic arterial buffer response in cirrhotic rodents in response to terlipressin.• Reductions in hepatic arterial flow fraction in the setting of acute-on-chronic liver failure.
