Neurodevelopmental outcomes in congenital heart disease: modifiable and nonmodifiable substrates

Area of Science:

• Neuroscience
• Cardiology
• Developmental Pediatrics

Background:

• Neurodevelopmental impairments are a common comorbidity in individuals with congenital heart disease (CHD).
• Despite improved survival rates due to advances in surgical and perioperative care, these impairments persist and significantly impact quality of life and independence.
• Understanding these neurodevelopmental outcomes is critical for comprehensive patient care.

Purpose of the Study:

• To review current knowledge on neurodevelopmental outcomes in the CHD population.
• To summarize neuroimaging findings and known risk factors associated with these impairments.
• To identify opportunities for optimizing neurodevelopmental outcomes in individuals with CHD.

Main Methods:

• This review synthesizes existing literature on neurodevelopmental outcomes in congenital heart disease.
• It examines findings from neuroimaging studies.
• It identifies and categorizes various risk factors contributing to neurodevelopmental impairments across the lifespan.

Main Results:

• Multiple risk factors contribute to neurodevelopmental impairments in CHD patients, spanning prenatal and adult-acquired factors.
• These factors include genetic abnormalities, cardiovascular physiology, environmental influences, social determinants of health, and mental health.
• While many risk factors are potentially modifiable, large-scale studies are needed to pinpoint the most significant ones.

Conclusions:

• Potentially modifiable risk factors for neurodevelopmental impairment in the CHD population have been identified.
• These findings provide a basis for future neuroprotective clinical trials aimed at improving neurodevelopmental outcomes.
• Early identification and intervention for these risk factors are essential for enhancing long-term well-being in individuals with CHD.
