Acute Liver Failure due to Altered Fontan Circulation in a Patient With Tricuspid Atresia: A Case Report.

Tricuspid atresia is a congenital malformation of the tricuspid valve resulting in a lack of blood flow between the right atrium and the right ventricle. Management generally involves staged surgical intervention enabling affected individuals to survive into adulthood. Although surgical intervention greatly improves morbidity and mortality in this patient population, there are many long-term complications associated with the creation of a surgical shunt. We report a case of a 33-year-old male with tricuspid atresia who underwent Fontan surgery as a child and presented to our hospital with acute liver failure.
