Atrial strain measurement in people with septic shock.
Official title: Assessment of Left And Right Atrial Strain in Septic Shock
Run by Centre Hospitalier Universitaire, Amiens · NCT06832436 · Data updated 2026-11-12
This project tests whether two echocardiography software packages and an AutoStrain tool give similar left and right atrial strain results using past heart ultrasound scans from adults treated for septic shock.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult ICU patients (>18 years) who had a transthoracic echocardiogram recorded during treatment for septic shock and who do not have major valvular disease, uncontrolled arrhythmia, mechanical circulatory support, or pacemaker dependence.
✕Probably not a fit
Patients without usable TTE images, with poor echogenicity, with significant valvular disease or fast arrhythmias at the time of imaging, or those on mechanical support or pacemaker-dependent are unlikely to benefit from the findings.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This retrospective, non-interventional study will re-analyze transthoracic echocardiograms obtained from adults treated for septic shock to compare left and right atrial strain measurements. Measurements will be performed using two software packages (ECHOPAC and UWS) and with AutoStrain technology, and multiple observers will repeat analyses to assess reproducibility. Exclusion criteria include poor image quality, significant valvular disease, high-rate arrhythmia at the time of imaging, mechanical circulatory support, or pacemaker dependence. The goal is to identify measurement differences between platforms and improve standardization of atrial strain assessment in critically ill patients.
Why it matters
Potential benefit: If successful, the work could make atrial strain measurements more reliable and comparable across hospitals, helping clinicians interpret echocardiograms more consistently in septic shock.
How similar studies have gone: Prior research has shown that atrial strain by speckle-tracking has prognostic value in cardiac disease, but direct comparisons between software platforms and AutoStrain validation specifically in septic shock are limited.
