Early failure of a bioprosthetic aortic valve due to thrombus formation while on rivaroxaban

Abstract

There is increasing evidence that bioprosthetic valve thrombosis (BPVT) is more common than previously thought. However, there are very few cases describing the occurrence of BPVT on therapeutic anticoagulation, and no previous cases are available stating the occurrence of BPVT on direct oral anticoagulant therapy. We describe the case of surgically managed aortic BPVT that was diagnosed while the patient was on rivaroxaban.
