Primary outcomePrimary: Shear Wave Speed (Liver Stiffness) — 1.18; 2.28; 2.22; 2.08 meters per second — p=<0.0001
Summary
The purpose of this study is to compare the liver stiffness, which can be caused by congestion and fibrosis in pediatric patients before and after a Fontan heart operation.
A new form of ultrasound elastography (Acoustic Radiation Force Impulse, or ARFI) will measure liver stiffness.
