Examining how the timing of surgery affects brain development in newborns with complex heart defects

Impact of Surgical Timing on the Neurodevelopmental Prognosis of Newborns With Complex Congenital Heart Disease

NA · Assistance Publique Hopitaux De Marseille · NCT04733378

This study is trying to see if doing heart surgery earlier on newborns with complex heart defects can help their brain development and reduce complications after surgery.

What this trial studies

This observational study aims to explore the relationship between the age at which newborns with complex congenital heart disease (CCHD) undergo surgery and their neurodevelopmental outcomes. It will assess whether earlier surgical intervention can reduce the incidence of white matter injuries observed through MRI and decrease postoperative complications. The study will also evaluate the length of hospital stays for these patients. By understanding these associations, the research seeks to identify potential neuroprotective strategies for infants with CCHD.

Who should consider this trial

Good fit: Ideal candidates are newborns aged 2 months or less with complex congenital heart disease requiring surgery within their first 2 months of life.

Not a fit: Patients with a birth weight less than 2 kilograms or those with chromosomal abnormalities associated with CCHD may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved neurodevelopmental outcomes for infants with complex congenital heart disease.

How similar studies have performed: While the approach of examining surgical timing in relation to neurodevelopmental outcomes is being explored, the specific focus on CCHD and its neuroprotective strategies is relatively novel.
