Abstract Objective: To determine the accuracy of a continuous cardiac output monitor (FloTrac sensor) for
measuring cardiac index in children with congenital heart disease undergoing cardiac catheterization. Cardiac index is a critical hemodynamic parameter measured during catheterizations in
children with congenital heart disease. This has been challenging to measure accurately and many
clinicians rely on predictive equations for calculating cardiac index.
Design: Prospective, nonrandomized trial.
Setting: Tertiary care congenital heart center.
Patients: Consecutive participants ≤18 years old undergoing clinically indicated cardiac catheterizations from September 2014 through August 2015.
Interventions: Oxygen consumption was measured using the Vmax Encore 229 monitor attached
