Impact of periprocedural anticoagulation strategy on the incidence of new-onset silent cerebral events after radiofrequency catheter ablation of atrial fibrillation

摘要

Background Silent cerebral events (SCEs) have been observed on diffusion-weighted cerebral magnetic resonance imaging (MRI) in a substantial number of asymptomatic patients after atrial fibrillation (AF) ablation procedures. The purpose of this study was to investigate if periprocedural oral anticoagulation (OAC) management affects the incidence of new-onset SCE after radiofrequency catheter ablation (RFCA) of AF.
