Echocardiography in congenital heart disease.

The utility of echocardiography in the evaluation of congenital cardiac disease is well established. The following discussion will be devoted to the application of single dimensional equipment in the assessment of selected congenital defects which will include secundum atrial defects, endocardial cushion defects, tetralogy of Fallot, Ebstein's anomaly of the tricuspid valve, and the use of systolic time intervals in assessing pulmonary artery diastolic pressures and pulmonary vasculature resistance. Since space is limited, only brief descriptions of these specific applications are possible and the readers are referred to more complete descriptions of the technic.
