18F-fluorodeoxyglucose positron emission tomography/computed tomography angiography (18F-FDG PET/CTA) is a new technique providing improved diagnostic accuracy in prosthetic valve endocarditis (1). PET/CTA findings have been recently incorporated as a major diagnostic criterion in guidelines for this condition (2).
Nonetheless, there are few available data on the morphological and metabolic features following prosthetic valve or valve-tube graft surgeries and their short-term evolution. Hence, images acquired after recent surgery should be carefully interpreted to avoid false-positive cases due to early post-operative inflammation. Therefore, the guidelines suggest PET/CTA use starting at 3 months after surgery, but not before.
The characteristic patterns of 18F-FDG uptake and the typical anatomic changes presented are intended to aid in the differentiation between inflammation and infection in these patients (Table 1, Figures 1, 2, 3, 4, 5, and 6).
