    Pacemaker-related infection detected by F-18-fluorodeoxyglucose positron emission tomography-computed tomography

    Lead endocarditis (LE) is one of the most feared complications and remains a challenging diagnosis in cardiology due to the possibility of an obscure clinical course and symptoms, leading to a delayed diagnosis, or even no diagnosis. F-18-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) appears to be a valuable imaging technique and has been shown to have advantages in the diagnosis of patients with fever of unknown origin. We present the case of a 52-year-old man with a 3-year history of intermittent fever, chills, anemia, and weight loss (13 kg). He was submitted to an extensive investigation to clarify his symptoms and all results were negative. LE was finally diagnosed by FDG PET/CT. This examination could become a useful noninvasive method for the detection of LE at an earlier stage, thus avoiding repeated tests and reducing the length of hospital stay.

    The Role of F-18-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in the Diagnosis of Left-sided Endocarditis: Native vs Prosthetic Valves Endocarditis
    (2020) CAMARGO, Raphael Abegao de; BITENCOURT, Marcio Sommer; MENEGHETTI, Jose Claudio; JR, Jose Soares; GONCALVES, Luis Fernando Tonello; BUCHPIGUEL, Carlos Alberto; PAIXAO, Milena Ribeiro; FELICIO, Marilia Francesconi; SOEIRO, Alexandre de Matos; STRABELLI, Tania Mara Varejao; MANSUR, Alfredo Jose; TARASOUTCHI, Flavio; JR, Mucio Tavares de Oliveira; CASTELLI, Jussara Bianchi; GUALANDRO, Danielle Menosi; POCEBON, Lucas Zoboli; BLANKSTEIN, Ron; ALAVI, Abass; MOORE, John Edmund; MILLAR, Beverley Cherie; SICILIANO, Rinaldo Focaccia
    Background: F-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG-PET/CT) has emerged as a useful diagnostic tool for suspected infective endocarditis (IE) in patients with prosthetic valves or implantable devices. However, there is limited evidence regarding use of F-18-FDG-PET/CT for the diagnosis of native valve endocarditis (NVE). Methods: Between 2014 and 2017, 303 episodes of left-sided suspected IE (188 prosthetic valves/ascending aortic prosthesis and 115 native valves) were studied. F-18-FDG-PET/CT accuracy was determined in the subgroups of patients with NVE and prosthetic valve endocarditis (PVE)/ascending aortic prosthesis infection (AAPI). Associations between inflammatory infiltrate patterns and F-18-FDG-PET/CT uptake were investigated in an exploratory ad hoc histological analysis. Results: Among 188 patients with PVE/AAPI, the sensitivity, specificity, and positive and negative predictive values of F-18-FDG-PET/CT focal uptake were 93%, 90%, 89%, and 94%, respectively, while among 115 patients with NVE, the corresponding values were 22%, 100%, 100%, and 66%. The inclusion of abnormal F-18-FDG cardiac uptake as a major criterion at admission enabled a recategorization of 76% (47/62) of PVE/AAPI cases initially classified as ""possible"" to ""definite"" IE. In the histopathological analysis, a predominance of polymorphonuclear cell inflammatory infiltrate and a reduced extent of fibrosis were observed in the PVE group only. Conclusions: Use of F-18-FDG-PET/CT at the initial presentation of patients with suspected PVE increases the diagnostic capability of the modified Duke criteria. In patients who present with suspected NVE, the use of F-18-FDG-PET/CT is less accurate and could only be considered a complementary diagnostic tool for a specific population of patients with NVE.
