Nemours surgeons are experts in performing heart and chest surgery to treat congenital heart disease, or conditions kids are born with.
The Society for Thoracic Surgery (STS) is a national organization that tracks congenital heart surgeries and sorts them into five categories, based on complexity.1 The group then determines a program’s expected survival rate for each category. The expected survival rate is a calculation based on a particular mix of children treated, and national results tracked over time.
Hospitals and surgeons voluntarily report this information to the STS, which shares it publicly.

- Nemours cardiothoracic surgeons achieved 100% survival rates for three of the five categories outlined by the STS.
- Our survival rates are better than the expected survival rates for all five categories.
- For the most complex cases (Category 5), which includes joint heart and lung transplant and the Norwood procedure, our survival rates were six points higher than the expected rate.
High Survival Rate for Neonatal Heart Surgery
Neonatal Heart Surgery Survival Rate1 2017 to 2021
- Nearly one in four children receiving heart surgery in our program is under a month old. Our success rates are strong.
- For all newborn surgeries performed, our overall average survival rate of 97.52% exceeds the expected rate of 96.68%.
