Brief Summary

Randomized Controlled Trial of High-Risk Pulmonary Embolism Comparing FlowTriever System vs. Standard of Care

Eligibility Criteria

Inclusion

  • Age at enrollment ≥18 years
  • Objective evidence of a proximal filling defect in at least one main or lobar pulmonary artery
  • High-risk class of acute PE
  • RV dysfunction, as defined RV/LV ratio ≥1.0
  • Willing and able to provide informed consent, 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

  • Prolonged cardiac arrest with loss of consciousness associated with neurological deficit.
  • Imaging evidence or other evidence that suggests, in the opinion of the Investigator, the patient is not appropriate for catheter-based intervention
  • Known pre-existing CTEPH, or CT signs of chronic PE that may point to pre-existing CTEPH
  • Recent stroke (\<14 days)
  • Recent cranial or spinal surgery (\<14 days)
  • Life-threatening active bleeding or hemorrhage into a critical area
  • Known intracranial tumor
  • End-stage medical condition with life expectancy \<3 months (irrespective of the severity of acute PE), as determined by the Investigator
  • Known sensitivity to radiographic contrast agents that, in the Investigator's opinion, cannot be adequately pre-treated
  • Inability to anticoagulate the patient, or known to have heparin-induced thrombocytopenia (HIT)
  • Current participation in another drug or device study that may interfere with the conduct of this trial
  • Ventricular arrhythmias refractory to treatment at the time of enrollment
  • 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 contraindication to use of FlowTriever System per local approved labeling
  • Subject is part of a vulnerable population (e.g., currently pregnant, breastfeeding or incarcerated) per local definitions
  • Subject was previously enrolled in this study
  • 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
