Detection of Undiagnosed Cardiac Sarcoidosis by FDG-PET and SPECT among Patients With Atrioventricular Block Followed in a Pacemaker Outpatient Clinic

Background: Atrioventricular block (AVB) is a common initial manifestation of cardiac sarcoidosis (CS) and classified as a major finding of CS. Previous paper reported that 19% of patients with AVB were undiagnosed CS. 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) plays an important role in the detection of CS because of high sensitivity. Methods: We prospectively examined patients with pacemaker implantation for AVB without known cardiac disease in a pacemaker outpatient clinic.
