Intestinal function in infants with severe congenital heart disease

Abstract

We evaluated digestive tract function in 21 young infants with severe congenital heart disease. One group had congestive heart failure and ventricular septal defect or single ventricle; the other had cyanosis and transposition of the great arteries. Enteric protein loss was excessive in eight patients, and steatorrhea was found in five. These abnormalities were mild and not related to the type or severity of the cardiac lesion. Available evidence points to a need of these babies for calories in excess of normal requirements for weight. The present study suggests that in designing dietary regimens for these very sick patients, their potential for defective gastrointestinal function must be considered. Because no consistent pattern of abnormalities in apparent, each patient who fails to thrive may deserve gastroenterologic evaluation.
