Neonatal patients with congenital heart defects (CHD) have changing physiology in the context of transitional period. Patients with CHD are at risk of low perfusion status or abnormal pulmonary blood flow. Near infrared spectroscopy has been used in neonatal intensive care units (NICU) to measure end-organ perfusion. The investigator plan on monitoring newborns with CHD admitted to the NICU with NIRS and echocardiography during the first week of life and correlate measures of perfusion from Dopplers to cerebral and renal NIRS.
