|Official Title:||Randomized, Controlled Study Comparing EKOS EkoSonic Ultrasound Accelerated Thrombolysis to Anticoagulation in the Treatment of Sub-massive Pulmonary Embolism|
|Study Start Date :||July 2010|
|Actual Primary Completion Date :||April 2013|
|Actual Study Completion Date :||May 2013|
Experimental: Ultrasound accelerated thrombolysis
Patients in this arm will receive anti-coagulation (intravenous unfractionated heparin) plus the EkoSonic Endovascular System will be used to deliver a low dose <20mg rt-PA (Actilyse) directly into the occlusive pulmonary thrombus.
Device: EkoSonic Endovascular System
The EkoSonic Endovascular System will be used to deliver < 20 mg of rt-PA ( Actilyse) directly into the occlusive pulmonary thrombus.
Active Comparator: Intravenous unfractionated heparin
Patients in this arm will receive the standard of care: intravenous unfractionated heparin used as anti-coagulation treatment.
Drug: Unfractionated heparin
Intravenous unfractionated heparin used for anticoagulation treatment
- Reduction of RV/LV Ratio [ Time Frame: 24 hours ]Change in the end-diastolic RV/LV ratio from baseline to 24 hours by echocardiography.
- Major Bleeding and Intracranial Bleeding at 30 Days. [ Time Frame: 30 days ]Bleeding will be classified as major if it is associated with a fall in the hemoglobin level of at least 2.0 g/dl, transfusion of ≥ 2 units of red blood cells, or involvement of a critical site (e.g., intracranial, intraspinal). To aid in evaluating the relationship of bleeding events to rt-PA administration, they will also be categorized by whether they occurred within 3 days after the initiation of thrombolytic therapy.
