Abstract
BackgroundWe assessed the diagnostic value of FDG PET/CT in a real-world cohort of patients with surgically managed infective endocarditis (IE). MethodsWe performed a retrospective analysis of all patients hospitalized in a tertiary IE referral medical center from January 2014 to October 2018 fulfilling the following criteria: ICD-10 code for IE and OPS code for both, heart surgery and FDG PET/CT. ResultsFinal analysis included 29 patients, whereof 28 patients had surgically proven IE. FDG PET/CT scan was true-positive in 15 patients (sensitivity (SEN) 56%) and false-negative in 12 patients. Combination of Duke criteria (DC) with FDG PET/CT scan resulted in gain of SEN for all patients with confirmed IE (SEN of DC 79% vs SEN of combination DC and FDG PET/CT 89%), driven by a relevant gain in PVE patients only (SEN of DC 78% vs SEN of combination DC and FDG PET/CT 94%). Interestingly, higher prosthesis age was observed in patients with false-negative scans. ConclusionsWe found a SEN of 56% for FDG PET/CT in a real-world cohort of patients with surgically proven IE which was associated with a 16% gain of IE diagnosis in patients with PVE when combined with DC.
Highlights
Despite medical advancements management of infective endocarditis (IE) is still challenging both from a diagnostic as well as from a therapeutic point of view

ESC guidelines are based on studies in which IE diagnosis in PVE and cardiac device-related infective endocarditis (CDRIE) patients was predominantly made by expert teams, respectively, by Duke classification
Summary
Despite medical advancements management of infective endocarditis (IE) is still challenging both from a diagnostic as well as from a therapeutic point of view. ESC guidelines are based on studies in which IE diagnosis in PVE and cardiac device-related infective endocarditis (CDRIE) patients was predominantly made by expert teams, respectively, by Duke classification.. More recent studies investigating the diagnostic value of FDG PET/CT in suspected IE have mainly used expert opinion or DC as reference standard for definite IE diagnosis.. An assessment of the diagnostic value of FDG PET/ CT via surgical confirmation as reference standard for definite IE is largely missing. This lack of definite surgical diagnosis may complicate interpretation of FDG PET/CT sensitivity (SEN) and specificity, which could have contributed to the high variation of FDG PET/CT SEN in the context of IE diagnostics.. We assessed the diagnostic value of FDG PET/CT in a real-world cohort of patients with surgically managed infective endocarditis (IE)
