Conditions

Outcome Measures

Primary Outcomes (2)

  • Effectiveness

    Change in RV/LV ratio post index procedure

    48 hours

  • Safety: Composite of Major Adverse Device-Related Events

    Device-related major bleeding at access, device-related death, clinical deterioration, pulmonary vascular injury or cardiac injury

    48 hours post index procedure

Secondary Outcomes (1)

  • Safety: Composite of Major Adverse Events

    30 days post index procedure

Study Arms (1)

Patients with Acute Pulmonary Embolism

EXPERIMENTAL

Patients undergoing mechanical thrombectomy for acute pulmonary embolism.

Device: ATC System

Interventions

The ATC System is designed to mechanically remove emboli and restore blood flow through the pulmonary arteries in patients experiencing acute PE

Patients with Acute Pulmonary Embolism

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is \> 18 and \< 90 years old
  • Clinical signs and symptoms consistent with acute PE
  • PE symptom duration ≤ 14 days
  • CTA evidence of proximal PE (filling defect in at least one main or lobar pulmonary artery as determined by the investigator)
  • CTA evidence of RV/LV ratio \> 0.9 note: based on Investigator's interpretation of RV/LV ratio at baseline;
  • Systolic BP ≥ 90 mmHg note: initial SBP may be \< 90 mmHg but ≥ 80 mmHg if the pressure recovers with volume resuscitation
  • Stable heart rate (HR) \< 130 BPM prior to procedure
  • Patient is deemed medically eligible for interventional procedure(s), per investigator guidelines and clinical judgment.
  • Subject or legally authorized representative (LAR) is willing and able to provide written informed consent prior to receiving any non-standard of care protocol specific procedures

You may not qualify if:

  • Prior PE \< 180 days from index procedure
  • Thrombolytic use \< 48 hours prior to baseline CTA
  • Pulmonary hypertension with peak pulmonary artery systolic pressure (PASP) \>70 mmHg by right heart catheterization
  • Vasopressor requirement after fluids to keep pressure at ≥90 mmHg
  • FiO2 requirement \>40% or \>6 LPM to keep oxygen saturation \>90%
  • Hematocrit \<28% (Note: hematocrit required within 6 hrs. of index procedure)
  • Platelets count \<100,000/µL
  • eGFR \<30 ml/min per 1.73 m2
  • International normalized ratio (INR) \>3
  • Major trauma injury severity score (ISS) \> 15
  • Presence of intracardiac lead in right ventricle or atrium placed within 6 months prior to screening assessment
  • Cardiovascular or pulmonary surgery within 7 days of index procedure
  • Actively progressing cancer treated by chemotherapeutics
  • Known bleeding diathesis or coagulation disorder
  • Left bundle branch block
  • +13 more criteria
