Cardiac Catheterization

Safer “Cath” Care for Kids

At the Nemours Cardiac Center, special heart doctors called “interventional cardiologists” use a procedure called a “cardiac catheterization” to diagnose and, whenever possible, treat heart problems. In a cardiac catheterization (sometimes called a “cath,” for short), the doctor inserts a catheter (a long, thin tube) into a blood vessel. Then the doctor guides it to the heart and the blood vessels around it. And because our “cath labs” were designed and built to deliver cardiac care for kids, our teams work together to deliver safer care in a kid-friendly space.

Services We Offer

Services We Offer


Some kids’ heart problems can be treated using cardiac catheterization instead of open-heart surgery. Sometimes children can both at the same time. At Nemours, our surgical and nonsurgical services and teams vary by location and condition. They include: 

  • board-certified cardiac anesthesiologists — to make sure your child is comfortable during the entire procedure
  • cardiac diagnostic testing and kid-friendly imaging — state-of-the-art tests for kids of all ages
  • diagnostic and interventional cardiac catheterization — diagnostic “caths” are used to find a heart problem, and interventional caths can treat or repair them
  • heart surgery — advanced procedures for congenital (present at birth) heart disease
  • hybrid procedures — a combination of cardiac catheterization and heart surgery done at the same time in a special cardiac suite
