Study Arms:
- ARFI Ultrasound (Type: EXPERIMENTAL): This study uses ultrasound scanning with acoustic radiation force impulse shear wave velocity imaging to measure pediatric liver fibrosis. Patients will be children who have had the Fontan operation. This is a non-invasive scan that uses sound waves to create images.

Based on this trial design, predict the completion outcome and termination type (if applicable).
