Pulmonary stenosis is a congenital (present at birth) heart defect that refers to narrowing (stenosis) of the pulmonary valve. Since this happens while a baby’s heart is developing, doctors can often identify it before birth. At Nemours, we offer leading-edge capabilities to detect heart problems early, including babies still in the womb — giving children the best chance.

You can trust the pediatric heart care in our Nemours Children's Cardiac Center to coordinate your child’s care from diagnosis to treatment. 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. We work closely with you and your family to provide support and services every step of the way.
