In addition to routine examinations (biological and microbiological tests, transesophageal or transthoracic ultrasound, transesophageal or transthoracic ultrasound, and leukocyte scintigraphy) of a parametric acquisition during the positron emission computed tomography parametric acquisition during positron emission computed tomography , this examination being itself planned in a standard way.~The definitive diagnosis according to the Duke-Li criteria will be established three months later in a multidisciplinary consultation meeting.~The final diagnosis according to the Duke-Li criteria will be made three months later in a multidisciplinary consultation meeting, blinded to the results of the parametric positron emission computed tomography, and with knowledge of the results of the standard positron emission computed tomography and the entire work-up.~Results and all the complementary work-up.
The objective of this study is to determine if early parametric positron emission computed tomography is useful to diagnose cardiac prosthetic valve infections.
