AbstractRecent advances for infants requiring early open heart surgery have resulted in a dramatic decline in mortality and severe morbidity. The developmental progress of these new survivors is currently being defined. Causes contributing to brain injury are multifactorial, and may involve preoperative, intraoperative, and postoperative events. Before surgery, these children often exhibit hypotonia, poor state regulation, microcephaly, and developmental delays. These findings are particularly prevalent in newborns. In the acute postoperative period, neurodevelopmental deficits continue to manifest clinically. Long-term follow-up studies indicate that subtle neurological deficits and global developmental lags are characteristic of this population. Overall, severe neurological sequelae are uncommon; however, mild to moderate developmental disabilities are prevalent. Functional limitations, academic achievements, and health-related quality of life are areas that deserve further attention.
