<unk>  (fuh-LOE) is a rare condition caused by the combination of four heart defects that are present at birth. These defects, which affect the structure of the heart, cause oxygen-poor blood to flow out of the heart and into the rest of the body. Infants and children with<unk>  usually have blue-tinged skin because their blood doesn't carry enough oxygen.<unk>  is often diagnosed during infancy or soon after. However,<unk>  may not be detected until later in life, depending on the severity of the defects and symptoms. With early diagnosis followed by appropriate treatment, most children with<unk>  live relatively normal lives, though they'll need regular medical care and may have restrictions on exercise.
