Due to the advancements in pediatric cardiothoracic surgery and medical management, more individuals with congenital heart disease are reaching reproductive age. It is well established that individuals with Fontan circulation are at an increased risk for maternal and fetal adverse outcomes including maternal cardiovascular complications, hypertensive disorders of pregnancy, preterm birth, and fetal growth restriction. Early onset of poor placental health likely related to chronically elevated central venous pressure/low cardiac output inherited to Fontan circulation may play a role in the development of these outcomes. In this case series, we present second-trimester placental imaging findings and pregnancy outcomes of three individuals with Fontan circulation who delivered at a tertiary center in the Southeastern United States.
