Implication

Observational study compares cardiac index accuracy using two methods in pediatric heart transplant recipients, indicating significant agreement issues.

Key Points

This research aims to compare cardiac index measurements using the Fick method and thermodilution in children following heart transplantation.
Single center prospective observational cohort study
Participants aged 5 to 18 who received orthotopic heart transplant
Utilized serial pair-wise comparisons of cardiac index measurements and analyzed data using various statistical methods
48% of cases showed normal cardiac index by Fick but abnormal by thermodilution
ICC between Fick CI and TDCI was 0.13, indicating low agreement
No significant change in TDCI over time since heart transplantation
