Eligibility criteria

• • Inclusion Criteria
• Subjects must meet each of the following criteria to be included in the study:
• • Age ≥ 18 years
• • Echo, computed tomographic pulmonary angiography (CTPA), or pulmonary angiographic evidence of any proximal filling defect in at least one main or lobar pulmonary artery
• • Including ALL of the following: Clinical signs and symptoms consistent with acute PE, or PESI class III-V, or sPESI ≥1; AND Hemodynamically stable AND; RV dysfunction on echocardiography or CT; AND Any one or more of the following present at the time of diagnosis: Elevated cardiac troponin levels; History of heart failure; History of chronic lung disease; Heart rate ≥110 beats per minute; SBP \<100mmHg; Respiratory rate ≥30 breaths per minute; O2 saturation \<90%; Syncope related to PE; Elevated Lactate
• • Intervention planned to begin within 72 hours of the later of either: confirmed PE diagnosis; OR if transferring from another hospital, arrival at the treating hospital
• • Symptom onset within 14 days of confirmed PE diagnosis
• • Exclusion Criteria
• Subjects will be excluded from the study for any of the following criteria:
• • Unable to anticoagulate with heparin, enoxaparin or other parenteral antithrombin
• • Index presentation with hemodynamic instability that are part of the high-risk PE definition in the ESC Guidelines 2019, including ANY of the following: cardiac arrest; OR systolic BP \< 90 mmHg or vasopressors required to achieve a BP ≥90 mmHg despite adequate filling status, AND end-organ hypoperfusion; OR systolic BP \< 90 mmHg or systolic BP drop ≥40 mmHg, lasting longer than 15 min and not caused by new-onset arrhythmia, hypovolemia, or sepsis
• • Known sensitivity to radiographic contrast agents that, in the Investigator's opinion, cannot be adequately pre-treated
• • Imaging evidence or other evidence that suggests, in the opinion of the Investigator, the patient is not appropriate for catheter-based intervention (e.g. inability to navigate to target location, clot limited to segmental/subsegmental distribution, predominately chronic clot)
• • Patient has right heart clot in transit identified at baseline screening
• • Life expectancy \< 30 days (e.g. stage 4 cancer or severe COVID-19 infection), as determined by the Investigator
• • Current participation in another drug or device study that, in the Investigator's opinion, would interfere with participation in this study
• • Current or history of chronic thromboembolic pulmonary hypertension (CTEPH) or chronic thromboembolic disease (CTED) diagnosis, per ESC 2019 guidelines
• • Invasive systolic PA pressure ≥70 mmHg prior to study device entering the body
• • Administration of bolus or drip/infusion thrombolytic therapy or mechanical thrombectomy for the index PE event within 48 hours prior to enrollment
• • Ventricular arrhythmias refractory to treatment at the time of enrollment
• • Known to have heparin-induced thrombocytopenia (HIT)
• • 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). This includes a contraindication to use of FlowTriever or CDT System (for example, EKOS System) per local approved labeling
• • Subject has previously completed or withdrawn from this study
• • Patient unwilling or unable to conduct the follow up visits per protocol.
