A Pilot Feasibility Study of Neurodevelopmental Surveillance After the Fontan Operation Using a Sedation-Free Brain MRI Approach
School-aged Fontan patients exhibited selective deficits in working memory and processing speed, while exploratory MRI analysis suggested lower cerebellar volumes in the Fontan group. The ultrafast sedation-free MRI protocol proved feasible for volumetric assessment and, when combined with neurocognitive assessments, may support future milestone-based surveillance and early intervention for at-risk children.
