The aim of this study is to determine the incidence of asymptomatic and symptomatic AF recurrences, using continuous subcutaneous ECG monitoring, in the long\u2010term follow\u2010up of patients with paroxysmal or persistent AF undergoing transcatheter ablation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and Results<\/jats:title><jats:p>In total 113 consecutive patients symptomatic for paroxysmal or persistent AF were enrolled. All patients underwent pulmonary vein isolation plus left linear lesions. The insertable cardiac monitor (ICM), subcutaneously implanted during the ablation procedure, recorded the amount of AF per day (daily burden) and per last follow\u2010up period (total AF burden). Based on symptoms and on scheduled 12\u2010lead ECG performed during follow\u2010up, 40 patients (35.4%) suffered AF recurrences. By means of ICM data, however, arrhythmia relapses were recorded within 75 patients (66.3%), of whom 35 (46.7%) were asymptomatic. Patients suffering symptomatic AF recurrences resulted, at univariate analysis, older (66.6 \u00b1 8.4 years vs 61.6 \u00b1 10.7 years) and suffering greater AF burden (88.8 \u00b1 26.9% vs 8.0 \u00b1
