Abstract

A 72-year-old man with non-valvular atrial fibrillation and metastatic liver and lung cancer after surgery for colon cancer developed thrombosis in the right atrium one month after decreasing the dose of warfarin due to the introduction of double anti-platelet therapy for coronary stent implantation. Restoring the warfarin dose with ordinary control for two months did not result in any changes in the size of the thrombus; however, the subsequent substitution of rivaroxaban (oral treatment with a direct Factor Xa inhibitor) for warfarin ultimately resolved the thrombosis.
