Subsequent CTIA and AF-ablation procedures were identified until March 1st, 2018. We collected information on patient comorbidities in the Danish National Patient Registry.RESULTS: We identified 2409 patients undergoing first-time CTIA. Median age was 66 (IQR 58-72) years, 1952 (81{\%}) were men, and 78 (3{\%}) patients had a history of previous ablation for AF. Acute procedural success was achieved in 2288 (95{\%}) patients. During mean follow-up of 4.0 ± 1.7 years, 242 (10{\%}) patients underwent CTI re-ablation and 326 (13.5{\%}) underwent ablation for AF. Baseline characteristics associated with CTI re-ablation included prolonged procedural time, unsuccessful index CTIA, age <75 years and CHA2DS2-VASc score <2. Hypertension, history of AF-ablation, age <65 years use of a contact force sensing catheter and CHA2DS2-VASc score <2 were associated with later ablation for AF.CONCLUSION: In a nation-wide cohort undergoing first-time CTIA for AFL, 10{\%} of patients underwent CTI re-ablation and 13.5{\%} ablation for AF during mean follow-up of 4.0 ± 1.7 years. Probability of a second procedure was higher in younger patients with less comorbidities.",

We collected information on patient comorbidities in the Danish National Patient Registry.RESULTS: We identified 2409 patients undergoing first-time CTIA. Median age was 66 (IQR 58-72) years, 1952 (81%) were men, and 78 (3%) patients had a history of previous ablation for AF. Acute procedural success was achieved in 2288 (95%) patients. During mean follow-up of 4.0 ± 1.7 years, 242 (10%) patients underwent CTI re-ablation and 326 (13.5%) underwent ablation for AF.
