Treatment for HLHS: the three surgeries

At Children's Colorado, we are committed to your child’s overall health and well-being. Our treatment plan, along with our wellness strategy, will keep you in the loop and involved in every decision. Treatment for hypoplastic left heart syndrome (HLHS) involves three stages of heart surgery:

  • Within days of birth, HLHS babies will have the Norwood procedure.
  • When they reach four to six months old, it's time for the Glenn surgery.
  • The third and final surgery, the Fontan, marks the beginning of some stability in the lives of patients with HLHS.

Our families discuss their experiences with HLHS surgeries

The Norwood, Glenn and Fontan procedures vary in terms of operating time, hospital stay and recovery. Derick and Karla discuss how they coped with Jaden’s surgeries, and they talk about life at home after each surgery.

Expert HLHS care, birth through childhood

From birth through the Glenn procedure, experts in our Complex Congenital Heart Disease and Development Clinic support HLHS babies and families every step of the way. We follow your baby very closely – both when they're in the hospital and after they return home – until they are ready for the final stage of treatment.

After your child has the Glenn procedure, our team in the Single Ventricle Clinic will care for them through their third and final surgery – the Norwood – and beyond. Our multidisciplinary caregivers help HLHS patients with any medical issues that may arise during childhood and with everyday matters like quality of life, going to school and self-esteem. It's just one way we're ensuring these children have a long, happy and healthy life.

HLHS survival: excellence in outcomes

Dedicated cardiac anesthesiologists

Babies born with HLHS have complex anatomy and physiology, making specialized anesthesiology critical. We have eight specially trained cardiac anesthesiologists solely dedicated to pediatric patients in the Heart Institute who are available 24/7.
