Nonbacterial Thrombotic Endocarditis (NBTE) is a rare manifestation of a hypercoagulable state, frequently due to an occult cancer, characterized by the deposition of fibrin vegetations on cardiac valves and rarely described on biological valvular prosthesis. Its diverse clinical presentation is commonly related to embolic complications. Its management mainly addresses the underlying cause. An anticoagulation regimen should be associated, and best evidence still favors low-molecular weight heparins. We report the case of a recurrent NBTE on a bioprosthetic aortic valve despite direct oral anticoagulation, in a patient with pancreatic adenocarcinoma.
