Brief Summary:
This single site study evaluates the efficacy of ultrasound accelerated thrombolysis using EKOS Endovascular Device with a standard infusion of thrombolytics for treatment of PE

Condition or disease Intervention/treatment
Thrombolytic Therapy Thrombolysis Mechanical Thrombolysis Pulmonary Embolism Device: EkoSonic Endovascular System

Detailed Description:
Previous clinical trials examining thrombolytics used to treat Acute Submassive PE, many times will use fixed dose and duration. Little research has been conducted on the physiologic implication of resolution of symptoms. It seems reasonable, that symptomatic relief results from some degree of hemodynamic normalization. This study will seek to examine the extent to which the hemodynamic impairment is normalized from a thrombolytic treatment protocol with an endpoint of therapy determined as resolution of presenting symptoms. Treatment plans will utilize the MBS (Modified Borg Scale) score to help evaluate and measure outcome-based care, quantifying shortness of breath.

Intervention Details:
  • Device: EkoSonic Endovascular System
    Ultrasound catheter-directed thrombolysis.

Primary Outcome Measures :
  1. Reduction of RV dysfunction [ Time Frame: 48 hours post catheter removal ]
    Reduction of RV dysfunction as evidenced by a reduction in RVSP and or a reduction in RV/LV ratio measured by echo at baseline and again at 48 ±6 hours post EKOS catheter removal

Hospital setting. Volunteers meeting the inclusion/ exclusion criteria who are patients of Fairfield Medical Center located in Lancaster, Oho

Inclusion Criteria:

  1. Acute symptomatic PE confirmed by CT, with filling defect in at least one main or segmental pulmonary artery.
  2. RV dysfunction as evidenced by RV/LV ratio > 0.9 on echo
  3. Ability to give informed consent or Legally Authorized Representative (LAR) is able to give consent

  12. Evidence of irreversible neurological compromise
  13. Life expectancy < 30 days
  14. Use of thrombolytics or glycoprotein IIb/IIIa antagonists within 3 days prior to inclusion in the study
