Right‑heart function and heart–lung interaction during ARDS with mechanical ventilation
Incidence and Evolution of Heart-lung Interaction in Acute Respiratory Distress Syndrome: the IVOLIA Study
This project will follow adults with ARDS on mechanical ventilation to see how positive‑pressure breathing affects the right heart over time and how that relates to circulation.

What this trial studies
This is an observational cohort of adult ICU patients with ARDS who are treated with mechanical ventilation and undergo serial echocardiography. Investigators will collect cardiac ultrasound, hemodynamic data, vasoactive drug use, and tissue oxygenation at predefined timepoints (first 24 hours, 48–96 hours, day 5–7, and within 48 hours of extubation). The study aims to describe the incidence and temporal evolution of right ventricular failure, identify phenotypes based on ultrasound and hemodynamic parameters, and relate these patterns to prognosis and volume status. Patients who are pregnant or have poor echocardiographic windows are excluded.
Who should consider this trial
Good fit: Adults (≥18) in intensive care with ARDS who are mechanically ventilated and can undergo serial echocardiography at the required timepoints are ideal candidates.
Not a fit: Patients who are not mechanically ventilated, who are pregnant, or who have poor echogenicity that prevents reliable heart measurements are unlikely to benefit from participating.
Why it matters
Potential benefit: If successful, the findings could help clinicians detect right heart dysfunction earlier and tailor ventilation and cardiovascular support to improve patient outcomes.
How similar studies have performed: Large prior studies have shown modern protective ventilation lowered the overall incidence of right ventricular failure in ARDS, but few longitudinal studies have mapped its evolution and hemodynamic consequences over time.
