People who have congenital heart disease are born with this condition but many individuals do not show any signs of heart defects until they are adults. Some people have heart procedures performed when they are infants or children and when they reach adulthood they often start showing symptoms of heart issues.
Individuals who had heart surgery as a child can develop heart arrhythmias due to the buildup of scar tissue at the surgical site. When a person has a heart arrhythmia, their heart may beat too slow, too fast or abnormally. When adults have congenital heart disease they are at risk of developing pulmonary hypertension, endocarditis and heart failure.
