Summary

Atrial fibrillation (AF) is responsible for substantial morbidity, including stroke. While catheter ablation has emerged as an effective treatment for symptomatic AF [Stabile G et al. Eur Heart J 2006], less is known about the incidence of either pre- or postablation asymptomatic AF [Rho RW, Page RL. Prog Cardiovasc Dis 2005]. This article discusses results from the Discerning the Incidence of Symptomatic and Asymptomatic Episodes of Atrial Fibrillation Before and After Catheter Ablation trial [DISCERN AF; Verma A et al. JAMA Intern Med 2013].
