E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
In patients with documented PE and right heart dysfunction, determine if treatment with ultrasound accelerated thrombolysis will significantly improve right heart function at 24 hours compared to patients receiving anticoagulation alone.

|
E.2.2 | Secondary objectives of the trial |

E.3 | Principal inclusion criteria |
1. Patients with acute PE symptoms < 14 days. 2. Filling defect by contrast-enhanced chest CT in at least one main or proximal lower lobe pulmonary artery (see also Appendix 2 “Indications for the placement of one or two EkoSonic catheters by contrast-enhanced chest CT”) 3. Right ventricular dysfunction confirmed by echocardiography where the RV/LV end diastolic diameter ratio is ≥ 1.0.
|
|
E.4 | Principal exclusion criteria |
1. Age less than 18 years or greater than 80 years 2. Index acute PE symptom duration > 14 days 3. Insufficient echocardiographic image quality in the apical or subcostal four-chamber view that prohibits the measurement of the right and left ventricular end-diastolic dimensions 4. Known significant bleeding risk 5. Administration of thrombolytic agents within the previous 4 days 6. Active bleeding 7. Known bleeding diathesis 8. Known coagulation disorder platelet count < 100.000/mm³, or previous use of vitamin K antagonists with INR <2.5 9. History of any intracranial or intraspinal surgery or trauma or intracranial/intraspinal bleed 10. Intracranial neoplasm, arteriovenous malformation, or aneurysm 11. Recent (< 3 months) GI bleeding. 12. Recent (< 3 months) internal eye surgery or hemorrhagic retinopathy; recent (< 10 days) major surgery, cataract surgery, trauma, CPR, obstetrical delivery, or other invasive procedure. 13. Allergy, hypersensitivity, or thrombocytopenia from heparin, rt-PA, or iodinated contrast, except for mild-moderate contrast allergies for which steroid pre-medication can be used. 14. Glomerular filtration rate (eGFR) < 50 ml/min as calculated by the Cockroft formula. 15. Hemodynamic collapse at presentation defined as: need for cardiopulmonary resuscitation; or systolic blood pressure < 90 mm Hg for at least 15 min, or drop of systolic blood pressure by at least 40 mm Hg for at least 15 min with signs of end organ hypoperfusion (cold extremities or low urinary output < 30 mL/h or mental confusion); or need for catecholamine administration to maintain adequate organ perfusion and a systolic blood pressure of > 90 mm Hg. 16. Severe hypertension on repeated readings (systolic > 180 mmHg or diastolic > 105 mmHg). 17. Pregnant, lactation or parturition within the previous 30 days (positive pregnancy test, women of childbearing age must be tested ). 18. Participating in any other investigational drug or device study. 19. Life expectancy < 90 days. 20. Inability to comply with study assessments (e.g. due to geographic distance). 21. Previous enrollment in this study 22. Any other condition that the investigator feels would place the patient at increased risk if the investigational therapy is initiated. 23. Known right-to-left shunt, for example from large patent foramen ovale or atrial septal defect 24. Large (>10 mm) right atrial or right ventricular thrombus
