Congenital heart disease (congenital heart defect) is one or more abnormalities in your heart's structure that you're born with. This most common of birth defects can alter the way blood flows through your heart. Defects range from simple, which might cause no problems, to complex, which can cause life-threatening complications.
Advances in diagnosis and treatment mean most babies who once died of congenital heart disease survive well into adulthood. However, signs and symptoms of the condition can occur in adults later in life, even those who had treatment as a child.
If you have congenital heart disease you might need care throughout your life. Check with your doctor to determine how often you should be seen as an adult.

Some congenital heart defects cause no signs or symptoms. For some people, signs or symptoms occur later in life. They can recur years after you've had treatment for a heart defect.
Common congenital heart disease symptoms you might have as an adult include:
If you're having worrisome symptoms, such as chest pain or shortness of breath, seek emergency medical attention.
If you have signs or symptoms of congenital heart disease or were treated for a congenital heart defect as a child, make an appointment to see your doctor.

Researchers aren't sure what causes most congenital heart disease, which develops in the womb. Heredity might play a role in some congenital heart disease.
The heart is divided into two chambers on the right and two on the left. To pump blood through the body, the heart uses its left and right sides differently.
The right side of the heart moves blood to the lungs through certain blood vessels (pulmonary arteries). In the lungs, blood picks up oxygen and then returns to the left side through the pulmonary veins. The left side of the heart then pumps the blood through the aorta and out to the rest of the body.
Congenital heart disease can affect any of the heart's structures, including valves, chambers, the wall of tissue that separates the chambers (septum) and arteries.
For some adults, problems with their heart defects arise later in life, even if treated in childhood. Repairing defects improves heart function, but might not make the heart completely normal.
Even if the treatment you received in childhood was successful, a problem can occur or worsen as you age. It's also possible that problems in your heart, which weren't serious enough to repair when you were a child, have worsened and now require treatment.
Then there are complications of childhood surgeries to correct congenital heart disease that can occur later, such as scar tissue in your heart that contributes to an abnormal heart rhythm (arrhythmia).

To determine whether you have a type of congenital heart disease or if the congenital heart defect is causing recent health problems, your doctor will take a medical history and conduct a physical exam, including listening to your heart with a stethoscope.
Your doctor then might order tests, including:
Exercise stress test. Connected to ECG leads, you exercise on a treadmill or a stationary bicycle so that your doctor can determine your level of conditioning and your heart's electrical activity, heart rate and blood pressure during exercise.
If you can't exercise, your doctor might give you medication to increase your heart rate. Your stress test may also include an echocardiogram and special sensors to determine your oxygen use.
Cardiac CT scan or MRI. For a cardiac CT scan, you lie on a table inside a doughnut-shaped machine. An X-ray tube inside the machine rotates around your body and collects images of your heart and chest.
Cardiac MRI uses a magnetic field and radio waves to create images of your heart. You lie on a table inside a long tubelike machine.
Cardiac catheterization. Your doctor might use this test to check blood flow and blood pressures in your heart. You'll likely be given sleeping medication before a catheter is inserted into an artery, starting in your groin, neck or arm. It's then threaded to your heart with guidance from an X-ray machine.
Dye is injected through the catheter, and the X-ray machine makes images of your heart and blood vessels. The pressure in the heart chambers can be measured during this procedure.

Congenital heart disease complications that might develop years after the initial treatment include:
Heart infection (endocarditis). Your heart comprises four chambers and four valves, which are lined by a thin membrane called the endocardium. Endocarditis is an infection of this inner lining, which generally occurs when bacteria or other germs enter your bloodstream and lodge in your heart. Untreated, endocarditis can damage or destroy your heart valves or trigger a stroke.
If you have an artificial (prosthetic) heart valve or your heart was repaired with prosthetic material, or if your heart defect wasn't completely repaired, your doctor might prescribe ongoing antibiotics to lower your risk of developing endocarditis.
Stroke. Stroke occurs when the blood supply to a part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen. A congenital heart defect can allow a blood clot to pass through your heart and travel to your brain.
Certain heart arrhythmias also can increase your chance of blood clot formation leading to a stroke.
Heart failure. Heart failure, also known as congestive heart failure, means your heart can't pump enough blood to meet your body's needs. Some types of congenital heart disease can lead to heart failure.
Over time, certain conditions such as coronary artery disease or high blood pressure gradually sap your heart of its strength, leaving it too weak or too stiff to fill and pump efficiently.

One important thing to do if you're an adult with congenital heart disease is to become educated about your condition. Topics you should become familiar with include:
Many adults with congenital heart disease lead full, long and productive lives. But it's important not to ignore your condition. Become informed about your disease; the more you know, the better you'll do.
