Submassive and Massive Pulmonary Embolism Treatment With Ultrasound Accelerated Thrombolysis Therapy

Summary

The purpose of this study is to determine if the EKOS EkoSonic® Endovascular Device when used in conjunction with recombinant tissue plasminogen activator (t-PA) as a treatment for acute PE will decrease the ratio of right ventricle (RV) to left ventricle (LV) diameter within 48 =/- 6 hours in participants with massive or submassive PE.
