The document provides an overview of the segmental approach and findings in echocardiographic evaluation of congenital heart disease. It describes abnormalities that can occur in the right ventricle inflow and outflow, left ventricle inflow and outflow, septations, and great vessel connections. Examples of specific defects that can be seen such as Ebstein's anomaly, cor triatriatum, pulmonary vein stenosis, and coarctation of the aorta are outlined. The echocardiographic views and features used to identify and characterize different types of abnormalities are also reviewed.
