Inclusion criteria

  1. Age at enrollment ≥18 years
  2. Objective evidence of a proximal filling defect in at least one main or lobar pulmonary artery
  3. High-risk class of acute PE
  4. RV dysfunction, as defined RV/LV ratio ≥1.0
  5. Willing and able to provide , or if unable, through a Legal Authorized Representative, with permitting research without prior consent as a third option (for Europe and UK sites only), provided compliance with IRB/EC approvals and adherence to regulatory, ethical and national standards

Exclusion criteria

Exclusion Criteria:

  1. Prolonged cardiac arrest with loss of consciousness associated with neurological deficit.
  2. Imaging evidence or other evidence that suggests, in the opinion of the Investigator, the patient is not appropriate for catheter-based intervention
  3. Known pre-existing CTEPH, or CT signs of chronic PE that may point to pre-existing CTEPH
  4. Recent stroke (\<14 days)
  5. Recent cranial or spinal surgery (\<14 days)
  6. Life-threatening active bleeding or hemorrhage into a critical area
  7. Known intracranial tumor
  8. End-stage medical condition with \<3 months (irrespective of the severity of acute PE), as determined by the Investigator
  9. Known sensitivity to radiographic contrast agents that, in the Investigator's opinion, cannot be adequately pre-treated
  10. Inability to anticoagulate the patient, or known to have heparin-induced thrombocytopenia (HIT)
  11. Current participation in another drug or device study that may interfere with the conduct of this trial
  12. Ventricular arrhythmias to treatment at the time of enrollment
  13. Subject has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject (e.g., compromise the well-being or that could prevent, limit, or confound the protocol-specified assessments), including a to use of FlowTriever System per local approved labeling
  14. Subject is part of a vulnerable population (e.g., currently pregnant, breastfeeding or incarcerated) per local definitions
  15. Subject was previously enrolled in this study
  16. Subject has received prior thrombolytic (systemic or catheter-directed) therapy for any reason or thrombectomy (surgical or catheter-based) therapy for index PE, within 30 days prior to randomization
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Timeline

2 registry updates since Sep 25, 2026
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

Started Dec 2024 (actual). Primary completion is estimated for Nov 2027, 35 months after the start.

Of 150 interventional studies with no phase under Pulmonary Embolism, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 51. This study's planned 35 months is above that.

How these figures are worked out, and which studies are left out of them.

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.
