Filter by:Acute pulmonary embolism (PE) accounts for 5-10% of in-hospital deaths. Systemic anticoagulation (AC) is the standard of care and thrombolysis is recommended for those at a higher mortality risk. Catheter-directed therapies, mainly standard infusion catheter thrombolysis (CDT) and ultrasound-accelerated thrombolysis (USAT), have been introduced as new more effective and safer treatment modalities. USAT is a modification of standard catheter lysis utilizing a system of local ultrasound to dissociate the fibrin matrix of the thrombus with simultaneous acoustic streaming of the thrombolytic agent, allowing more efficient thrombolysis. However, there is limited comparative effectiveness data against standard multi-side hole catheter infusion. More rapid clearance of pulmonary thrombus by USAT compared to standard CDT may prove to be clinically beneficial and cost effective. Alternatively, if thrombus clearance is similar, the cost of USAT may exceed the cost of CDT (equipment and disposables), without realization any advantage.
Evaluate the safety and effectiveness of the FlowTriever System for use in the removal of emboli from the pulmonary arteries in the treatment of acute pulmonary embolism.
Patients with Submassive Pulmonary Embolism treated with ultra-sound therapy will have an improved right ventricular function 72 hours post treatment.
The ULTIMA study is intended to prove that in patients with pulmonary embolism and a right ventricular end diastolic diameter to left ventricular end diastolic diameter ratio ≥1 (RV/LV ratio) will benefit from treatment with ultrasound accelerated thrombolysis (rt-PA) as compared to unfractionated heparin anticoagulation. Specifically, at 24 hours the RV/LV ratio will be significantly reduced in the treatment arm compared to the control arm.
An exploratory, multicenter, randomized, placebo-controlled, double blind, dose escalation study comparing a standard therapy for submassive pulmonary embolism (Enoxaparin sodium) to a combined therapy of Drotrecogin alfa (activated) plus Enoxaparin sodium.
