Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Clinical signs and symptoms consistent with acute PE with duration of 14 days or less
  • RV/LV ratio ≥ 0.9 assessed by diagnostic computed tomographic angiography (CTA) or echocardiogram
  • Frontline endovascular treatment with the Indigo Aspiration System per IFU
  • Patient is ≥ 18 years of age
  • Informed consent obtained per Institutional Review Board/Ethics Committee requirements

Exclusion criteria

  • Contraindication to systemic or therapeutic doses of anticoagulants (e.g. heparin)
  • Stage IV (metastatic) cancer, active lung cancer or previous history of surgery in the affected lung(s) or chest radiation
  • Known serious, uncontrolled sensitivity to radiographic agents
  • Life expectancy < 180 days
  • Patients on ECMO
  • Pregnant patients
  • Current participation in another investigational drug or device study that may confound the results of this study. Studies requiring extended follow-up for products that were investigational but have since become commercially available are not considered investigational studies
  • Other medical, social, or psychological conditions that, in the opinion of the Investigator, precludes the patient from appropriate consent, could limit the patient's ability to participate in the study, including compliance with follow-up requirements, or that could impact the scientific integrity of the study

Treatment and study plan

Indigo Aspiration System

Device

Indigo Aspiration System

Primary outcomes

  1. Safety: Composite of major adverse events

    Time frame: 48 hours

    A composite of device-related death, major bleeding, device-related clinical deterioration, device-related pulmonary vascular injury and device-related cardiac injury

  2. Performance: Change in RV/LV Ratio

    Time frame: 48 hours post-procedure

    Change in RV/LV Ratio (matched imaging pairs CTA or echocardiogram, as available)

Secondary outcomes

  1. Quality of Life assessed via PEmb-QoL

    Time frame: 90 days post-procedure

    Self-assessment of PE related complaints and daily living limitations (including work and social)

  2. Quality of Life assessed via EQ-5D-5L

    Time frame: 90 days post-procedure

    Self-assessment of activities of daily living

  3. Functional outcome assessed NYHA

    Time frame: 90 days post-procedure

    Physician assessment of heart failure symptoms and activity level

  4. Functional outcome assessed via 6MWT

    Time frame: 90 days post-procedure

    Walking distance over a 6 minute period to assess functional capacity

  5. Perceived dyspnea assessed via Borg Scale

    Time frame: 90 days post-procedure

    Category rating scale to measure perceived dyspnea

  6. Incidence of device related SAE(s)

    Time frame: 365 days

  7. Any-cause mortality

    Time frame: Within 30 days

  8. Symptomatic PE recurrence

    Time frame: Within 30 days
