Fontan associated liver disease: Evidence for early surveillance of liver health in pediatric Fontan patients

Publication date: Available online 29 November 2018Source: Canadian Journal of CardiologyAuthor(s): Steven L. Rathgeber, Kevin C. HarrisAbstractThe growing awareness of Fontan associated liver disease (FALD) in adults with Fontan physiology has provided the impetus to better understand the natural history of Fontan associated liver disease (FALD) and develop a reliable non-invasive method to diagnose and monitor liver health in this population. Biochemical and imaging tests have been investigated to determine their association with liver pathology. The congestive hepatopathy that develops after the Fontan procedure has made interpreting these tests challenging. We have reviewed and summarized the current understanding and ongoing challenges with respect non-invasive measures of liver health in Fontan patients including biochemical tests, elastography, hepatic ultrasound, cross-sectional imaging, and hemodynamics and how they relate to liver pathology. It has been demonstrated from biopsy data that liver disease is universal and progressive in Fontan patients. Traditional biochemical tests, elastography, and imaging methods are often abnormal in Fontan patients, but do not reliably indicate significant liver pathology. Although a reliable means for surveillance of FALD remains elusive, this remains an active area of investigation with promising recent developments. Therapeutic options for FALD are limited with cardiac transplant as the only option that can stabilize FALD patho...
