Biomarkers of fibrosis and portal hypertension in Fontan-associated liver disease in children and adults.

Background: Fontan-associated liver disease (FALD) refers to structural and functional changes of the liver caused by the physiology of the Fontan palliation. Currently, liver biopsy is the gold standard to assess liver fibrosis of FALD.

Aim: Investigate biomarkers correlating with severity of liver biopsy fibrosis in FALD.
