Congenital heart disease is one or more problems with the heart’s structure that exist since birth. Congenital means that you’re born with the defect. Congenital heart disease, also called congenital heart defect, can change the way blood flows through your heart. Some congenital heart defects might not cause any problems. Complex defects, however, can cause life-threatening complications.

Advances in diagnosis and treatment have allowed babies with congenital heart disease to survive well into adulthood. Sometimes, signs and symptoms of congenital heart disease aren’t seen until you’re an adult. If you have congenital heart disease you likely will need care throughout your life. Check with your doctor to determine how often you need a checkup.
