Compare cardiac index by right ventricular waveform vs. thermodilution in septic shock patients
Official title: Comparison of Cardiac Index Measurement by Analysis of the Right Ventricular Pressure Curve and by Thermodilution During Pulmonary Artery Catheterization Using Swan Ganz IQ™.
Run by Assistance Publique - Hôpitaux de Paris · NCT07628023 · Data updated 2026-11-12
This study tests whether the continuous cardiac index estimated from the right ventricular pressure waveform matches the thermodilution measurement in adults with septic shock who already have a Swan-Ganz catheter in place.

Is this trial a fit for you?
✓Likely a good fit
Adults (18+) in the ICU who have a Swan-Ganz IQ catheter placed as part of their care and have undergone thermodilution measurements.
✕Probably not a fit
Patients with conditions that disrupt right heart waveform analysis or with unreliable catheter data may not benefit from the continuous estimate.

What this trial studies
This observational study analyzes data from ICU patients with septic shock who have a Swan-Ganz IQ catheter. It compares the traditional thermodilution cardiac index with a continuous estimate derived from the right ventricular pressure waveform. The goal is to see how closely the continuous method agrees with the gold-standard thermodilution in real clinical settings, including during volume expansion tests. The study plans to assess concordance across different clinical situations that may affect right heart function, such as right ventricular dysfunction or valvular disease. Findings could influence how clinicians monitor cardiac output in the ICU when rapid, ongoing estimates are desirable.
Why it matters
Potential benefit: If the continuous method aligns well with thermodilution, clinicians could monitor cardiac index more rapidly and conveniently without repeated injections.
How similar studies have gone: Prior work suggests variable agreement between continuous waveform-based estimates and thermodilution, making independent clinical data valuable for validation.
