Congenital Heart Defects refers to problems with heart structure that are present at birth. The term, “congenital,” literally means something you are born with. These abnormalities can take many forms and occur throughout the heart, affecting the interior walls of the heart, valves inside the heart, or the arteries and veins that carry blood to or from the heart to the rest of the body. It’s important to note that when a patient suffers from an abnormality, the condition is not necessarily the same as heart disease. By working with your doctor, you can learn about the different types of congenital heart defects, treatments, and tests.
