In a rare and historic achievement, Children’s Hospital Colorado successfully completed its first dual heart and liver transplant in a pediatric patient. The life-saving surgery was performed on 11-year-old Gracie Greenlaw, whose congenital heart condition eventually led to liver failure. Dozens of specialists worked together for years to prepare for a moment like this, executing a complex, 16-hour operation. Now months later, Gracie is home, in school, and thriving.
