157 Stentless Aortic Valve bioprosthesis Dehiscence – A Possible Infective Endocarditis with Atypical Presentation but Serious Consequences

Conclusion We report a frequent and atypical clinical and microbiological presentation of possible PVIE occurring on stentless bioprosthesis and a striking increased incidence after 2004 which corresponds to changes in the manufacturing process. Clinicians should be aware of this atypical clinical presentation. The stentless Cryo-Life O’Brien ® bioprosthesis is not anymore implanted at our institution.
