Infants with congenital heart disease (CHD) are nearly twice as likely to be low birth weight (LBW) as infants without CHD.¹ Previous studies suggested that LBW infants have increased risk of poor outcomes from corrective surgical repair, likely due to the effects of cardiopulmonary bypass and associated intracranial bleeding. Consequently, definitive surgical intervention was often delayed, leading to potential heart failure, cardiogenic shock, and death. This study aimed to elucidate if weight or age was correlated with outcomes for infants who undergo CHD repair.
