Pulmonary valve regurgitation (pulmonary insufficiency or “PR”) is a congenital (present at birth) heart defect. PR can also be caused by other health conditions such as infections and pulmonary hypertension. At Nemours Cardiac Center, we offer leading-edge capabilities to detect heart problems early, including babies still in the womb. If your child is experiencing PR, our pediatric cardiologists and heart surgeons work together with other Nemours specialists to find the reason for your child’s symptoms. Our expert pediatric care teams provide the latest in research-backed care, with supportive services for your family — from diagnosis through treatment, and beyond.
