Ultrasound technology has been available for several decades with it’s origins in science, industry and military innovations. Ultrasound imaging is a non invasive procedure used for many diagnostic purposes, and is a standard of care for pregnant women. Fetal growth can be followed and congenital anomalies, including congenital heart disease (CHD), can be identified. Screening for CHD is performed as part of routine prenatal care, usually between 18 to 24 weeks gestation. The effectiveness of screening for CHD in Alberta or Canada is not known but is low in other jurisdictions. This thesis: describes the impact of CHD on the patient, family and health care system; defines the capabilities of fetal echocardiography; determines the proportion of fetuses with CHD detected prenatally in Alberta; reports risk factors for missed disease; and describes clinical outcomes for those with and without a prenatal diagnosis.
