Congenital heart defects are the most common birth defect and are the number one cause of death from birth defects during the first year of life.Congenital heart defects are structural problems with the heart present at birth. They result when a mishap occurs during heart development soon after conception and often before the mother is aware that she is pregnant. Defects range in severity from simple problems, such as "holes" between chambers of the heart, to very severe malformations, such as complete absence of one or more chambers or valves .These defects are usually but not always diagnosed early in life.All heart disease is not congenital but may occur during childhood such as heart damage due to infection. This type of heart disease is called acquired .Children also can be born with or develop heart rate problems such as slow, fast, or irregular heart beats, known as "arrhythmias".
Out of 1000 births, 8 babies will have some form of congenital heart disorder, most of which are mild. If you or other family members have already had a baby with a heart defect, your risk of having a baby with heart disease may be higher.Estimates suggest that about 1,000,000 Americans have a congenital heart defect. Approximately 35,000 babies are born with a defect each year.the reason defects occur is presumed to be genetic, only a few genes have been discovered that have been linked to the presence of heart defects. Rarely the ingestion of some drugs and the occurrence of some infections during pregnancy can cause defects.
Severe heart disease generally becomes evident during the first few months after birth. Some babies are blue or have very low blood pressure shortly after birth. Other defects cause breathing difficulties, feeding problems, or poor weight gain.Nearly twice as many children die from congenital heart disease in the United States each year as die from all forms of childhood cancers combined. Over 91,000 life years are lost each year in the US due to congenital heart disease. Virtually all children with simple defects survive into adulthood. Although exercise capacity may be limited, most people lead normal or nearly normal lives. The presence of a serious congenital heart defect often results in an enormous emotional and financial strain on young families at a very vulnerable time. Patient/family education is an important part of successful coping.
