Becker muscular dystrophy and successful intervention with mechanical thrombectomy of right atrial clot-in-transit with pulmonary embolism

Abstract

This case report discusses the effectiveness of the Inari FlowTriever system in treating a right atrial (RA) clot in-transit in a 55-year-old male patient with Becker's muscular dystrophy (BMD). BMD is an X-linked recessive muscle disease caused by mutations in the gene that code for the protein dystrophin, which is associated with partially functional dystrophin in variable amounts. Right heart thrombi (RHT) are thrombi that can be visualized in the right atrium, right ventricle, or proximal surrounding vasculature. The Inari FlowTriever system was used to treat RA clot in-transit and removed acute, subacute, and chronic clot in a single session without the use of thrombolytics and subsequent ICU stay. The estimated blood loss with the FlowSaver system was approximately 150 mL. This report complements the FLARE study by highlighting the effectiveness of the FlowTriever system for mechanical thrombectomy of RA clot-in-transit in a patient with BMD.
