Which advice would you give to someone who has just been diagnosed with Hypoplastic Left Heart Syndrome?

Hypoplastic Left Heart Syndrome (HLHS) is a complex congenital heart defect where the left side of the heart is underdeveloped, requiring a series of specialized surgical interventions known as the staged palliation process. Receiving a diagnosis of Hypoplastic Left Heart Syndrome is life-changing, but with multidisciplinary care, many patients are now living into adolescence and adulthood with improved quality of life.

How do I build the right care team for Hypoplastic Left Heart Syndrome?

Managing Hypoplastic Left Heart Syndrome requires a specialized team. You should seek care at a high-volume pediatric cardiac center that performs a high number of Norwood, Glenn, and Fontan procedures annually. Your core team must include a pediatric cardiologist specializing in congenital heart disease, a cardiothoracic surgeon, an intensivist, and a nutritionist to manage the complex caloric needs often associated with Hypoplastic Left Heart Syndrome.

What are the most important steps for daily management?

Living with Hypoplastic Left Heart Syndrome involves careful monitoring of energy levels and growth. Key management strategies include:

• Maintaining strict adherence to prescribed cardiac medications (such as ACE inhibitors or diuretics).


• Tracking daily weights and oxygen saturation levels as directed by your clinical team.


• Prioritizing neurodevelopmental follow-ups, as children with Hypoplastic Left Heart Syndrome are at a higher risk for learning or developmental delays.


• Ensuring consistent follow-up appointments to monitor for long-term complications like protein-losing enteropathy or arrhythmias.

How can I find support for Hypoplastic Left Heart Syndrome?

You are not alone; 28 members of the DiseaseMaps.org community are currently navigating the complexities of Hypoplastic Left Heart Syndrome. Connecting with others through specialized foundations like Sisters by Heart or Mended Little Hearts provides vital emotional support and practical advice for both patients and caregivers. Sharing experiences with those who understand the unique journey of Hypoplastic Left Heart Syndrome can significantly reduce the isolation often felt after a diagnosis.
