The Fontan operation, used to palliate single ventricle congenital heart disease, increases venous pressure in the liver and is associated with Fontan associated liver disease (FALD), for which liver fibrosis is the final common pathway. Elastography (ultrasound [US] or MRI) can be used to non-invasively measure liver stiffness associated with liver fibrosis. However, these measures are confounded in Fontan patients due to venous congestion. The purpose of this study was to prospectively document the stiffening effect of passive hepatic congestion following the Fontan operation and track changes in liver stiffness over the post-operative period.
