Summary

This study tested a noninvasive monitor that uses light to measure oxygen levels in the liver of children with heart conditions. Researchers wanted to see if this method could replace the usual needle-based blood draw. The study included 100 children undergoing heart catheterization. If successful, this monitor could help doctors check liver health more easily and safely.
