Abstract: |
OBJECTIVE: The aim of the study was to investigate the value of F-fluorodeoxyglucose positron-emission tomography combined with computed tomography (F-FDG-PET/CT) in diagnosing native valve endocarditis (NVE). PATIENTS AND METHODS: All patients with bacteremia and suspicion of NVE between January 2013 and June 2016 were identified from the hospitals' register and retrospectively included if echocardiography and F-FDG-PET/CT were performed within 14 days. F-FDG-PET/CT scans were scored independently by two nuclear medicine physicians. F-FDG-PET/CT was compared with the modified-Duke criteria and a multidisciplinary consensus. RESULTS: A total of 88 patients were included. In 10 patients with definite NVE according to the modified-Duke criteria, three (30.0%) patients had increased F-FDG uptake in or around the heart valves and seven (70.0%) patients had no increased F-FDG uptake. In patients without definite NVE according to the modified-Duke criteria, 89.7% (70/78) of the patients had no increased F-FDG uptake in or around the heart valves. Of all 20 patients with NVE according to multidisciplinary consensus, nine (45.0%) patients had increased F-FDG uptake in or around the heart valves and 11 (55.0%) patients had a normal F-FDG-PET/CT result. CONCLUSION: A negative F-FDG-PET/CT result should not be interpreted as an exclusion of NVE. In patients with possible or rejected NVE according to the modified-Duke criteria, F-FDG-PET/CT could be used in case of sustained suspicion of NVE owing to its high specificity in case of abnormal FDG uptake at the valve region. F-FDG-PET/CT is important for detecting metastatic infection which already warrants the need to perform F-FDG-PET/CT in all patients with suspected NVE.
