Study summary

Right ventricular failure (RVF) is an independent factor of mortality for many pulmonary diseases. Currently, RVF is defined as the incapacity of the RV to maintain the flow without dilating to use the Frank-Starling law (i.e., increase of the ejection volume associated to an increase of the preload). RVF is associated to RV systolic dysfunction which is conventionally defined as a decrease of the RV ejection fraction (RVEF) \< 45%.

In the intensive care unit (ICU), acute RVF is mainly due to the acute respiratory distress syndrome (ARDS), sepsis or septic shock, and less often to severe pulmonary embolism or RV infarction.

The anatomical complexity of the RV precludes any geometrical assumption to estimate its volume, hence its ejection fraction (EF) using two-dimensional (2D) echocardiography. For this reason, the evaluation of RV systolic function is currently based on parameters used as surrogates of RVEF: fraction area change in 2D-mode, tricuspid annular plane systolic excursion (TAPSE) in M-mode, and maximal velocity of the systolic S' wave using tissue Doppler imaging.

Real-time three-dimensional (3D) echocardiography now enables accurate on-line measurement of RV volume and provides at the bedside the non-invasive assessment of RVEF. 3D transthoracic echocardiography (TTE) has been validated to measure RV volume and RVEF compared to MRI which is the gold standard. However, 3D transesophageal echocardiography (TEE) has not yet been validated in this specific clinical setting, while 2D TEE is frequently used in ICU in ventilated and sedated patients. Accordingly, the diagnostic ability of 3D echocardiography to quantify RV systolic function in ICU patients with RVF of any origin is currently unknown.

Groups and cohorts

  • Real-time three-dimensional echocardiography

    Diagnostic Test: Real-time three-dimensional echocardiography

Interventions

  • Diagnostic testReal-time three-dimensional echocardiography

    The initial hemodynamic assessment and monitoring using echocardiography will be performed within 12h following ICU admission. TTE will be performed systematically as first-line examination and TEE will be performed only on ventilated and sedated patients for whom additional information is required for their management, according to the standards of care of the participating centers. In that case, TEE will be performed immediately after TTE. 3D echocardiographic measurements will be performed after the examination by two independent intensivists expert in critical care echocardiography who will be blinded from the usual parameters of RV systolic functions; these parameters will be measured during the examination to guide the management of patients, according to the standard of care of the participating centers.

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Apr 2020 to primary completion in Sep 2023, 41 months.

Of 25 observational studies under Ventricular Dysfunction, Right, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 26. This study's 41 months is above that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 9, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
