Pediatric Cardiac Catheterization

Key Points about Cardiac Catheterization

  • Cardiac catheterization is a procedure in which a long, flexible tube (catheter) is put into a blood vessel. The doctor then guides the catheter into the heart to find and treat heart problems.
  • Your child might need a cardiac catheterization to diagnose a heart problem or to fix an already existing problem (such as a congenital heart defect); diagnostic and interventional catheterizations may also be performed.
  • The procedure is done in a cardiac catheterization (cath) lab in a hospital. Your child's doctor and a specially trained staff of nurses and technicians will be alongside your child throughout the process.
