Overview
Congenital heart disease (CHD) is the most common type of birth defect, accounting for about 1% of all cases. Although mild cases of CHD are not detected until after discharge, most of the critical CHD cases are identified soon after birth requiring surgery or catheter-based intervention in the first year of life. CHD is broadly classified into three major groups, namely, cyanotic CHD, ductal-dependent CHD and critical CHD. Cyanotic CHD involves defects that lead to mixing of deoxygenated blood into the systemic circulation. Ductal-dependent CHD relies on the patency of the ductus arteriosus for supply of blood to the pulmonary or systemic outflow which allows adequate mixing between the parallel circulations. Lesions requiring surgery or catheter-based intervention in the first year of life are referred to as critical CHD which includes ductal-dependent and cyanotic lesions, as well as forms of CHD that, although not requiring surgery in the neonatal period, do necessitate intervention in the first year of life, such as a big ventricular septal defect or an atrioventricular canal defect (or atrioventricular septal defect).
