Developmental delay in infants with congenital heart disease. Correlation with hypoxemia and congestive heart failure

Area of Science:

• Pediatrics
• Developmental Neuroscience
• Cardiology

Background:

• Congenital heart disease (CHD) is a common birth defect.
• Early detection of developmental delays in infants with CHD is crucial for timely intervention.
• Factors like congestive heart failure and hypoxemia may impact neurodevelopment in infants with CHD.

Purpose of the Study:

• To assess the mental and motor development of infants with congenital heart disease.
• To evaluate the relationship between clinical factors and developmental outcomes.
• To identify early indicators of developmental delay in this population.

Main Methods:

• Utilized Bayley Scales of Infant Development for assessment.
• Conducted clinical neurological examinations.
• Analyzed data from 173 infants with congenital heart disease, considering age, sex, congestive heart failure, hypoxemia, and hospitalization.

Main Results:

• Congestive heart failure was significantly associated with both mental and motor developmental delay.
• Hypoxemia and hospitalization were linked to delayed motor development.
• Developmental delays were observable as early as 2 months of age.

Conclusions:

• Infants with congenital heart disease, particularly those with congestive heart failure, are at high risk for developmental delays.
• Hypoxemia and hospitalization exacerbate motor development issues.
• Early identification of developmental delays in infants with CHD is possible and essential.
