NIRS in Congenital Heart Defects - Correlation With Echocardiography
An observational study of Congenital Heart Defect and Single-ventricle, run by McGill University Health Centre/Research Institute of the McGill University Health Centre at 1 site in Canada.
Trial summary
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. Read more about this study

About this study
Official title: Do Cerebral and Renal Saturations Measured With Near-infrared Spectroscopy Correlate With Echocardiographic Markers of Perfusion and Cardiac Performance in Congenital Heart Disease?
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.
Read the detailed description
Near infrared spectroscopy (NIRS) is a noninvasive technology that uses infrared light to measure Oxygen levels in tissue or organs. However, the use of this monitoring tool has not been the standard of care in the immediate post-natal life. The investigator wish to study this way of monitoring Oxygen, which consists of using a sticker on the skin of the forehead and the skin of the abdomen to continuously monitor the Oxygen content of the brain and the kidneys and compare NIRS values in the CHD population to echocardiographic measures of blood flow and heart function to see if/how this simple, non-invasive tool could help us to closely monitor Oxygen in babies with CHD.
The NIRS probe (sticker) will be put on the side of the abdomen (the flank to monitor the kidney saturation of oxygen) and on the forehead (to monitor the brain saturation of oxygen) for 7 days or until the baby is discharged home, has a procedure in cath-lab or has surgery. An echocardiography will take place daily (for up to 7 days, or up to discharge, or up to cardiac intervention) during the day and should last about 15- 20 minutes. Newborns will be recruited during the fetal consultation with the cardiologist or neonatologist; or will be recruited during their neonatal admission. Only newborns admitted to the NICU will be eligible to the study.
The investigator would like to better understand the way babies with cardiac conditions transition once they are born and into their first week of life. During that important time, there are a lot of changes that can impact the cardiac adaptation: vessels in the lungs that relax, vessels in the body that contract. Echocardiography and NIRS may help us better appreciate these changes by evaluating the delivery of oxygen to organs. Echocardiography may reveal some information about this adaptation by looking at the cardiac performance by ultrasound and blood flow patterns.
Approximately 100 participants from this hospital will take part in this study.

Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jun 2025; AzTrials last refreshed its copy on 6 Nov 2026.
