Neurological complications of congenital heart disease

Abstract

Neurological complications contribute significantly to mortality and morbidity from congenital heart disease with serious long-term consequences. Congenital heart disease has also been shown to adversely influence the neurodevelopmental outcome of children. In developing countries such as India, majority of congenital heart defects remains uncorrected and major neurological complications are frequently encountered. Stroke and brain abscess are the commonest neurological complications of unoperated congenital heart disease. In developed countries the focus has now shifted to neurological complications of cardiac surgery in the very young as a result of cardiopulmonary bypass and total hypothermic circulatory arrest. A variety of neurological disturbances are now being increasingly recognized and are currently the subject of intense investigations. In this review the neurological complications of uncorrected congenital heart disease and the common neurological complications that result from operations for congenital heart disease will be discussed.
