Hypoplastic left heart syndrome (HLHS) is a rare but serious congenital (present at birth) heart defect where the left side of the heart doesn’t develop properly. As a result, it’s smaller and weaker, so the right side of the heart must work extra hard to pump blood to the lungs and the rest of the body. Since HLHS happens while a baby is growing in the womb, it’s often diagnosed during prenatal tests.
Hypoplastic Left Heart Syndrome
Early Diagnosis and Expert Care for HLHS
At Nemours, we offer leading-edge capabilities to detect heart problems early, including babies still in the womb — giving children the best chance. If your child is diagnosed with hypoplastic left heart syndrome, you can trust the pediatric heart care in our Nemours Cardiac Center. Our board-certified, fellowship-trained pediatric cardiologists and cardiothoracic surgeons (specialists in surgical procedures of the chest, including the heart and lungs) are here to answer your questions, address your concerns, and offer treatment options, including hypoplastic left heart syndrome surgery. Our cardiac teams offer the latest in research-backed care, delivered with compassion.
Services We Offer for HLHS
The expert teams in our Nemours Cardiac Center locations offer a full range of pediatric heart care to diagnose and treat hypoplastic left heart syndrome. Services vary by specialist and location, but may include:
- Fetal Diagnostics. Early detection in our perinatology and fetal medicine centers help us diagnose congenital heart defects and make a treatment plan for when your baby’s born.
- Cardiac Diagnostic Testing. State-of-the-art, noninvasive and minimally invasive tests for kids of all ages.
- Cardiology. Medicines are used to help manage oxygen and blood flow.
- Cardiac Catheterization. Most babies with HLHS are also born with an atrial septal defect (or “ASD”), but it might be repaired using a catheter (thin, flexible tube) to help relieve symptoms.
- Heart Surgery. Surgical repair for hypoplastic left heart syndrome will be done in a series that includes the Norwood, Glenn and Fontan procedures.
