Insights

Infants with congenital heart disease (CHD) in Japan show impaired growth and neurodevelopment after surgery, particularly those with univentricular (UV) physiology. Early surgery timing did not impact these outcomes.

Area of Science:

  • Pediatric Cardiology
  • Developmental Pediatrics
  • Surgical Outcomes

Background:

  • Infants with congenital heart disease (CHD) undergoing cardiopulmonary bypass (CPB) surgery face risks of impaired growth and neurodevelopment.
  • Limited research exists on risk factors, especially the timing of initial surgical intervention, for these impairments.

Purpose of the Study:

  • To investigate risk factors for growth and neurodevelopmental impairments in infants with CHD post-CPB surgery.
  • To compare outcomes between univentricular (UV) and biventricular (BV) physiology and assess the impact of surgical timing.

Main Methods:

  • Retrospective analysis of term singleton infants with CHD who underwent CPB surgery (2015-2021).
  • Neurodevelopment assessed using the Kyoto Scale of Psychological Development at 18-22 months.
  • Risk factors analyzed included CHD type (UV vs. BV), birth weight, sex, and CPB surgery timing (<28 days vs. ≥28 days).

Main Results:

  • Impaired growth was observed in both UV and BV groups, with significantly lower body weights in the UV group.
  • Neurodevelopmental impairment (total Developmental Quotient [DQ] < 85) affected 40.7% of children, with UV physiology being a significant risk factor (aOR 3.11).
  • Timing of initial CPB surgery was not associated with growth or neurodevelopmental outcomes.

Conclusions:

  • Infants with CHD in Japan experience impaired growth and neurodevelopment post-CPB surgery by 18-22 months.
  • Univentricular (UV) physiology is a significant risk factor for neurodevelopmental impairment in these infants.
