Shorter stature in Fontan survivors is linked to worse health and non-cardiac issues. Increased adiposity correlates with heart changes and reduced exercise capacity, impacting long-term outcomes.

Area of Science:

  • Pediatric Cardiology
  • Growth and Development
  • Cardiovascular Health

Background:

  • Fontan operation survivors often exhibit abnormal height and adiposity.
  • These anthropometric deviations may negatively impact functional outcomes.
  • Understanding these associations is crucial for long-term Fontan patient care.

Purpose of the Study:

  • To investigate the relationship between anthropometric measures (height and body mass index) and functional health status in Fontan survivors.
  • To identify associations between abnormal growth and adiposity with clinical testing results.
  • To inform clinical management and improve long-term outcomes for this vulnerable population.

Main Methods:

  • Analysis of cross-sectional data from 544 Fontan patients.

Wireless Telemetry Device Implantation in a Fontan Ovine Model for Continuous and Long-Term Hemodynamic Monitoring

Published on: May 2, 2025

  • Patients categorized by height-z score (<-1.5 or ≥-1.5) and BMI-z score (<-1.5, -1.5 to 1.5, or ≥1.5).
  • Associations examined with exercise, echocardiography, MRI, and Child Health Questionnaire data, adjusting for covariates.

    • Main Results:

    • 23% of patients had shorter stature (height-z <-1.5), associated with pre-Fontan atrioventricular valve regurgitation and developmental problems.
    • Shorter stature correlated with lower physical and psychosocial functional health status scores.
    • Higher BMI-z was linked to increased ventricular mass-to-volume ratio and reduced exercise capacity, despite similar functional health status scores compared to normal BMI.

    Conclusions:

    • Abnormal anthropometry, including short stature and altered adiposity, is prevalent in Fontan survivors.
    • Shorter stature is a marker for poorer functional health and co-existing non-cardiac conditions.
    • Increased adiposity is associated with adverse cardiac remodeling and impaired exercise performance, highlighting significant long-term implications.
