Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

FlowTriever Arm

FlowTriever Arm subjects are defined as those subjects where FlowTriever is used as the Primary Treatment for pulmonary embolism.

No interventions assigned to this group

Context Arm

Subjects with high-risk pulmonary embolism who are treated with non-FlowTriever therapies.

No interventions assigned to this group

Prior Therapy Arm

Subjects presenting with low/intermediate-risk PE who received advanced therapy but subsequently progressed to high-risk PE in the same hospital setting/admission.

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Age \>=18 years Treatment team determines pulmonary embolism is the cause of shock, and the PE is high-risk per the protocol definitions

Exclusion Criteria

* Out of hospital cardiac arrest with Glasgow Coma Scale of ≤8
* Witnessed cardiac arrest with ongoing CPR \>30 minutes
* Contraindication to anticoagulants, i.e. heparin or alternative
* Hematocrit \<28%
* Platelets \<25,000/μL
* INR \>8
* Intracardiac thrombus and/or intracardiac clot in transit
* Known anaphylactic sensitivity to radiographic agents that cannot be pre-treated
* History of pulmonary hypertension with systolic pulmonary arterial pressure \>70 mmHg
* Presence of chronic medical conditions with estimated \< 90 days life expectancy per physician discretion (should not consider the current pulmonary embolism and its treatment)
* Current participation in another drug or device treatment study that, in the Investigator's opinion, would interfere with participation in this study
* Patient is known to be COVID-19 positive at hospital admission (patient has active COVID-19)
