Eisenmenger syndrome occurs when a congenital heart defect is not detected early enough to be treated before damage to the lung arteries occurs. If you or your child receives a diagnosis of a heart defect, it's important to start treatment promptly, including having surgeries or procedures performed to help correct the defect.

Family history of heart defects also increase the risk of a baby developing a congenital heart defect, including the possibility of developing Eisenmenger syndrome. Talk to your doctor about screening other family members for heart defects if you've been diagnosed with a heart defect or Eisenmenger syndrome.
