Studies have shown women are less likely to be referred for catheter ablation, are older at the time of ablation, and are more likely to have recurrence after ablation. However, in most studies investigating AF ablation outcomes, the female cohorts were relatively small. The impact of sex on the outcome and safety of ablation procedures is still unclear.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To investigate sex\u2010based differences in outcomes and complications after AF catheter ablation, with a significant female cohort<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>In this retrospective study, patients undergoing AF ablation from January 1, 2014, to March 31, 2021, were included.

Women had higher CHA<jats:sub>2<\/jats:sub>DS<jats:sub>2<\/jats:sub>\u2010VASc (congestive heart failure, hypertension, age, diabetes, stroke, vascular disease, sex category) scores (3 vs. 2; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) than men, expectedly, as the female sex warrants an additional point. 25.3% female patients had PersAF at the time of diagnosis versus 35.3% male patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). At the time of ablation, 31.8% female patients had PersAF as compared to 43.1% male patients (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), indicating progression of PAF to PersAF in both sexes. Women tried more AADs than men before ablation (1.13 vs. 0.98; <jats:italic>p<\/jats:italic>\u2009=\u2009.002).
