Incidence of Atrial Fibrosis in Non-Valvular Atrial Fibrillation Patients and its Impact on Recurrence after Pulmonary Vein Antral Isolation

摘要

Background:Atrial fibrillation (AF) is the most common sustained arrhythmia; it affects 1%–2% of the general population []. Many studies demonstrated an association between atrial fibrosis and AF []. There is increasing evidence that even in patients with lone AF; the AF is an arrhythmic manifestation of a structural atrial disease which has been described as fibrotic atrial cardiomyopathy []. It is unknown whether the presence of atrial fibrosis has any impact on post pulmonary vein antrum isolation outcome.
