The effects of congenital heart disease on the lungs.

The alterations in anatomy and physiology, which often accompany congenital heart disease, may have a major impact on the child's lungs. These changes in pulmonary blood flow and ventilation are usually demonstrable on chest radiography and should be recognized as manifestations of the underlying lesion and not mistaken for primary lung disease. Correlation with the clinical history and physical examination are essential for correct interpretation, but radiological findings should be viewed objectively and without bias to provide accurate and valuable information to the treating physician.
