ABSTRACT

Better Late than Never - Fever of Unknown Origin in a Patient with a Prosthetic Valve Abstract. A patient presents with worsening of his general condition, chills and dyspnoea on exertion. With a history of aortic valve replacement, infective endocarditis is suspected, but due to negative imaging by transesophageal echocardiography and negative blood cultures cannot be confirmed. Finally, Cutibacterium acnes prosthetic valve endocarditis is diagnosed after culture of C. acnes during an extended incubation period of blood cultures, the presence of embolic complications and a characteristic finding on PET-CT scan.
