Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  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 Outcome Measures :
  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 ]

Study Population
Patients with acute pulmonary embolism
Criteria

Inclusion Criteria:

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

Exclusion Criteria:

  1. Contraindication to systemic or therapeutic doses of anticoagulants (e.g. heparin)
  2. Stage III/IV cancer or cancer which requires active chemotherapy during the course of the study
  3. Known serious, uncontrolled sensitivity to radiographic agents
  4. Life expectancy < 180 days
  5. Patients on ECMO
  6. Pregnant patients
  7. 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
  8. 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
