Additionally, a negative 18F-FDG-PET/CT report was given in 5/12 patients with “definite TAVI-IE” (42%), including 2 with very low CRP levels (< 10 mg/L); 2 with moderate cardiac suppression due to high serum glucose levels during the scan (> 10 mmol/L); and 1 with no signs of endocarditis on any of the imaging modalities, but a final diagnosis of definite TAVI-IE (positive blood cultures, prosthetic heart valve, fever, and cerebral embolization). Here, CRP is linked to endocarditis.
