Symptoms
Some congenital heart defects cause no signs or symptoms. In some cases, signs or symptoms of the disease appear later. Symptoms can return years after receiving treatment for heart defects.
Common symptoms of congenital heart disease in adults include:
Abnormal heartbeat (arrhythmia)
Bluish color to the skin, lips, and nails (cyanosis)
Shortness of breath
Tired quickly on exertion
Swelling of body tissues or organs (edema)
