Fontan connections made using a lateral tunnel (LT) or extracardiac (EC) pathway were evaluated over time using MR. LT pathways generally increased in diameter while EC pathways did not. Normalized LT and EC diameters decreased relative to somatic growth, while descending aortic diameter increased in parallel with somatic growth. Changes in pathways over time are complex and require further investigation.
