The association between immunodeficiency and congenital heart disease

Summary The predilection of children with congenital heart disease (CHD) to infection may be explained in part by an underlying immunodeficiency disorder. Some 13 syndromes in which immunodeficiency and CHD may coexist have been reported in the medical literature. In addition, immunoglobulin and T-cell deficiencies have been found in nonsyndromal patients with CHD. The diagnosis of immunodeficiency should be entertained in such children, as early recognition of an immunodeficiency disorder can result in improved antimicrobial and immunological management.
