Hypoplastic Left Heart Syndrome (HLHS)

Giving hope a heartbeat

Our pediatric experts can tell families a lot about their baby's hypoplastic left heart syndrome (HLHS) diagnosis and the treatment to come. One thing they can't tell them: how it will feel.

That's why we connected a family just diagnosed with HLHS with a family who's been there — to answer questions, to shed light and to offer hope — from diagnosis to surgery to recovery. These conversations heal. Watch them on the following pages.

Meet the families

Our experienced family

Karla, Derick and Jaden have been through quite a journey with HLHS, including three surgeries, tough recoveries and renewed hope for a long and happy life.

HLHS surgeries

Babies born with HLHS need three surgeries – the Norwood, the Glenn and the Fontan – before they're 3 years old.
