What happens in congenital heart disease?

Asymptomatic at birth
2. Associated with immunodeficiency
3. Cyanotic or acyanotic
4. Seen more commonly in low birth weight babies

Often asymptomatic, at least until pulmonary resistance falls and duct closes. Digeorge syndrome (22q) consists of cellular immunodeficiency (related to the thymus) and is associated with coarctation. Routine neonatal examination misses about 50% of cases. Cyanotic vs cyanotic is the easiest way to think about the many different conditions. Mean birth weight is reduced for all cardiac conditions except transposition.
