Hypoplastic left heart syndrome (HLHS) is a heart defect where the left side of the heart doesn’t develop properly. This means it’s smaller and weaker, so the right side of the heart must work extra hard to pump blood to the rest of the body. 

At Nemours Children's, we are experts at detecting 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 specialists in our Nemours Children's 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.

In addition, we offer the Nemours app , which includes special features specifically for patients with HLHS and allows your child's cardiac care team to proactively monitor your child and potentially identify any emerging problems as quickly as possible.
