Outcome Measures

Primary Outcomes (1)

  • Change in mMRC dyspnea score from

    Baseline (state at time of admission to hospital) to 30-day follow-up.

Secondary Outcomes (12)

  • Change in Pulmonary Embolism Quality of Life Questionnaire (PEmbQOL)

    Procedure to 30-day, 3-month, and 6-month follow up.

  • Change in Six Minute Walk Test (6MWT) (distance covered in meters over 6 minutes)

    Pre-procedure to 30-day, 3-month, and 6-month follow up.

  • Echocardiogram Measurements: Change

    Pre-procedure to 30-day and 6-month follow up

  • Echocardiogram Measurements: Change

    From pre-procedure echocardiogram compared to 30-day and compared to 6-month follow up

  • ICU Length of Stay

    Length of index hospitalization, length of hospitalization median of 9.1 days, length of ICU stay median 3.1 per JNS

  • +7 more secondary outcomes

Study Arms (1)

  • E3. Known sensitivity to radiographic contrast agents that cannot be pre-treated
  • E4. Life expectancy \< 6 months
  • E5. Current participation in another study that may interfere with the patient's participation in this study.
  • E6. Inability to consent
