Nutritional Strategies to Optimize Outcomes among Infants with Congenital Heart Disease

Abstract

Growth failure is common among infants with congenital heart disease (CHD), affecting approximately half of all infants with CHD. Achieving good growth is difficult secondary to both cardiac and noncardiac factors that affect energy expenditure and nutritional intake. Growth failure is associated with poor outcomes, including mortality, prolonged length of hospital stay, delayed cardiac surgery, postoperative complications, and neurodevelopmental delay. Clinical practice varies widely when it comes to how nutrition is managed in these infants, with varying approaches to enteral feeding initiation, advancement, and discontinuation. This variation persists despite several practice guidelines that have been created in recent years to guide nutritional care. Standardized feeding protocols have been proven to reduce growth failure and improve outcomes for this patient population. Centers and clinicians should be encouraged to adopt existing guidelines, or create their own from evidence-based literature, to improve growth and outcomes for infants with CHD.
