Percutaneous thrombectomy in patients with massive and very high-risk submassive acute pulmonary embolism.

Objective: Examine FlowTriever thrombectomy feasibility in high-risk PE patients.

Background: The FlowTriever thrombectomy system (Inari Medical, Irvine, CA) can reduce right ventricle (RV) strain in acute submassive pulmonary embolism (PE) patients. This technology has not been studied in higher risk PE patients.
