Why the study?
The FlowTriever thrombectomy system reduces right ventricle strain in acute submassive pulmonary embolism, but had not been studied in higher-risk pulmonary embolism patients.
Does percutaneous aspiration thrombectomy improve hemodynamics and clinical outcomes in patients with massive and very high-risk submassive acute pulmonary embolism?
Population
34 high-risk acute PE patients with vasopressor dependence, respiratory failure, or decreased cardiac index
Comparison
FlowTriever percutaneous thrombectomy
Design
Multicenter retrospective analysis
Follow-up
Mean 205 days
Key result
FlowTriever aspiration thrombectomy in high-risk acute pulmonary embolism patients achieved successful clot removal in 94.1% of patients and significantly improved cardiac index (p=0.01).

Does percutaneous aspiration thrombectomy improve hemodynamics and clinical outcomes in patients with massive and very high-risk submassive acute pulmonary embolism?
Toma et al. (2020) conducted an observational in massive and very high-risk submassive acute pulmonary embolism (n=34). FlowTriever thrombectomy was evaluated on Clot removal success. FlowTriever aspiration thrombectomy in high-risk acute pulmonary embolism patients achieved successful clot removal in 94.1% of patients and significantly improved cardiac index (p=0.01).
