Magnetic Resonance Imaging (MRI) to Evaluate Brain Injury in Congenital Heart Disease (CHD Brain)
Role of Inflammatory Response in Brain Injury Following Neonatal Cardiac Surgery
Infants with congenital heart disease (CHD) requiring surgery frequently have brain injury seen on magnetic resonance imaging (MRI). This occurs in approximately 40% of these newborns, and even though these are full-term infants, the injury seen closely resembles the same form of brain injury that can be seen in premature babies. Much like premature newborns, infants with CHD also have long-term neurodevelopmental problems (in over 50%).
The investigators do not know why infants with CHD get this specific form of brain injury. One risk factor is felt to be the inflammation that occurs in response to heart-lung bypass (cardiopulmonary bypass, or CPB), a necessary feature of open-heart surgery. Newborns have a stronger inflammatory reaction to CPB than older children or adults. The investigators do know from animal experiments and other human data that inflammation can be harmful to the developing brain.
The investigators hypothesize that children with CHD requiring surgery as a newborn have brain injury due to toxicity from the inflammatory response. The investigators will test this by enrolling newborns undergoing heart surgery to measure markers of inflammation, measure brain injury by MRI, and then test their developmental outcome at 1 and 2 years of age.
An association between inflammation and injury might impact what medicines are chosen to protect the brain in future studies, even in other populations such as preterm infants.
