The Role of F18-Fluorodeoxyglucose Positron Emission Tomography in Identifying Patients at High Risk for Lethal Arrhythmias From Cardiac Sarcoidosis and the Use of Serial Scanning to Guide Therapy

Substantial literature exists linking inflammation with arrhythmia, in particular with regards to serological markers of systemic inflammation. Regional inflammation can be identified using positron emission tomography (PET) with the radiotracer F18-fluorodeoxyglucose (F18-FDG). In the current series, we demonstrate novel applications of cardiac PET using F18-FDG and N13-ammonia radiotracers in the evaluation and treatment of arrhythmia associated with cardiac sarcoidosis. These applications include defining the cause of arrhythmia, identifying arrhythmias that will be amenable to medical management, and guiding therapy using serial scanning. Though these applications are promising, prospective multicenter studies are needed to provide better understanding of the utility of PET imaging in the diagnosis and treatment of arrhythmias. Za’Darius Smith Jersey
