Infants with Congenital Heart Defects

40,000 infants each year

Most common birth defect - 1/100 infants in the U.S.

25% have complex defects

High risk for adverse social, emotional, behavioral, & cognitive outcomes

Early Environment of Infant with Serious Heart Defect

Physical environment• Bright lighting• Loud sounds• Painful procedures

Social environment• Aversive touch• Multiple caregivers • Maternal separation

• Intermittent caregiving

Maternal-Infant Separation = Delayed Interaction

Effects of delayed interaction: animal models

Specific Aims

1. Describe the relationship between infant and maternal affect and behavior during feeding.

2. Compare the relationship between infant and maternal affect and behavior in infants with transposition of the great arteries (TGA) and healthy infants.

3. Examine stability or change in the relationship over time.

Methods

Secondary data analysis

Sample: 15 infants with TGA and their mothers, and 16 healthy infants and their mothers

Data collection: Dyads were videotaped during feeding at two weeks and two months of age

Parent-Child Early Relational Assessment

Parent• Positive affective involvement, sensitivity, &

responsiveness• Negative affect and behavior

Infant • Positive affect, communicative, and social skills • Dysregulation and irritability

Dyadic • Mutuality and reciprocity • Dyadic tension

Conclusions

Infants with TGA were more likely to be dysregulated and irritable.

TGA dyads were more likely to have interactions characterized by tension.

Infants with TGA are at risk for suboptimal maternal-infant interactions.

………………..……………………………………………………………………………………………………………………………………..

Future Research

• Describe diverse trajectories in the development of the maternal-infant relationship.

• Identify specific experiential and individual factors associated with suboptimal maternal-infant interactions, e.g. maternal, infant, and environmental characteristics.

• Develop and test interventions to support positive maternal-infant relationships.
