Insights

Children with single-ventricle heart disease often require reinterventions. This study found high rates of surgical and catheter procedures after staged palliation, highlighting the need for better interventions.

Area of Science:

  • Pediatric Cardiology
  • Congenital Heart Disease Research
  • Health Services Research

Background:

  • Congenital heart disease (CHD) affects many children, with functionally single-ventricle (f-SV) conditions requiring complex staged palliation.
  • Reintervention rates are crucial metrics for evaluating healthcare quality in pediatric CHD management.
  • Understanding reintervention patterns informs clinical practice and patient outcomes.

Purpose of the Study:

  • To evaluate the rates of surgical and catheter reinterventions in children with f-SV CHD.
  • To assess the incidence of additional procedures following staged palliation for f-SV CHD.
  • To provide data for improving care and developing interventions for f-SV CHD.

Main Methods:

  • Retrospective cohort study of children born with f-SV CHD (2000-2018) in England and Wales.
  • Utilized national registry data with survival ascertained up to 2020.
  • Employed competing risk analysis to determine the incidence of additional procedures, accounting for death or transplantation.

Main Results:

  • Of 3307 children with f-SV CHD, 27.9% required additional surgery and 39.1% needed catheter interventions during follow-up.
  • Cumulative incidence of additional surgery was 17.6% at 6 months post-stage 1, 8.3% at 2 years post-stage 2, and 8.4% at 5 years post-stage 3.
  • Cumulative incidence of additional catheter interventions was 18.0% at 6 months post-stage 1, 14.7% at 2 years post-stage 2, and 23.7% at 5 years post-stage 3.

Conclusions:

  • Quantifying reintervention rates is essential for informing parents and healthcare professionals involved in f-SV CHD care.
  • The study highlights a significant need for interventions aimed at reducing reinterventions in this population.
  • Further research should focus on strategies to minimize adverse outcomes associated with staged palliation for f-SV CHD.
