The association of right heart thrombus (RiHT) and massive pulmonary embolism (PE) has an incidence of 4-18%. It is a life-threatening condition that requires emergent diagnosis and treatment with reported fatal outcomes up to 21% in 14 days. Endovascular mechanical thrombectomy of right heart clot has been described focused on the use of AngioVac (AngioDynamics, Latham, NY, USA), however, a recent report supported the safety of image guided FlowTriever(Inari Medical Inc., Irvine, CA, USA). Our case report describes the use of FlowTriever device as a unique modality to treat clot in transit and massive PE when thrombolysis is contraindicated.
