Congenital heart defects & disease
The majority of congenital heart diseases occur as an isolated defect and are not associated with other diseases. However, they can also be a part of various genetic and chromosomal syndromes, such as Down syndrome, trisomy 13, Turner's syndrome, Marfan syndrome, Noonan syndrome, Ellis-van Creveld syndrome.

Congenital heart disease (CHD) is a broad term that can describe a number of different abnormalities affecting the heart. Congenital heart disease is, by definition, present at birth although its effects may not be obvious immediately. In some cases, such as coarctation of the aorta, it may not present itself for many years and a few lesions such as a small ventricular septal defect (VSD) may never cause any problems and are compatible with normal physical activity and a normal life span.

According to the American Heart Association, approximately 35,000 babies are born each year with some type of congenital heart defect. Congenital heart disease is responsible for more deaths in the first year of life than any other birth defects. Many of these defects need to be followed carefully; though some heal over time, others will require treatment.

Some congenital heart diseases can be treated with medication alone, while others require one or multiple surgical interventions. There has been significant improvement in the risk of death from congenital heart disease surgery, from approximately 30% in the 1960s and 1970s to approximately 5% today.
