Three year experience of a clinical cardiovascular genetics program for infants with congenital heart disease.

An inpatient cardiogenetics program significantly increases the diagnostic rate, the detection of complex phenotypes with dual diagnoses, the identification of incidental genetic diagnoses associated with changes in care, and significantly decreases the likelihood of multiple tests being completed on an individual patient. Increased medical geneticist involvement in programs that care for infants with CHD should be encouraged to improve patient care and genetic testing utilization.
