Insights
Congenital heart disease (CHD) can cause serious neurological complications, including stroke and brain abscess, particularly in unoperated cases. Cardiac surgery for CHD also presents neurological risks, necessitating further investigation.
Area of Science:
- Neurology
- Cardiology
- Pediatrics
Context:
- Congenital heart disease (CHD) significantly impacts neurological health, leading to mortality and morbidity.
- In developing nations, uncorrected CHD frequently results in severe neurological complications like stroke and brain abscess.
- Developed countries increasingly focus on neurological issues arising from cardiac surgery in infants, linked to cardiopulmonary bypass and hypothermic circulatory arrest.
Purpose:
- To review the neurological complications associated with both uncorrected congenital heart disease and surgical interventions for CHD.
Summary:
- Neurological complications are a major concern in congenital heart disease (CHD), affecting neurodevelopment and survival.
- Unoperated CHD commonly leads to stroke and brain abscess.
- Cardiac surgery for CHD, especially in young children, carries risks of neurological disturbances due to procedures like cardiopulmonary bypass.
Impact:
- Highlights the critical need for understanding and managing neurological risks in pediatric patients with CHD.
- Informs clinical practice and research directions for improving neurodevelopmental outcomes in CHD survivors.
- Emphasizes the dual burden of neurological complications in both operated and unoperated CHD populations globally.
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.
