OAT discontinuation during follow\u2010up was permitted in selected patients per physician discretion. At last follow\u2010up, allowing for multiple ablations, 172 (43.0%) patients were free of AF recurrence. Two hundred and seven (51.8%) discontinued OAT at some point; 174 (43.5%) were off OAT at last follow\u2010up. Patients without AF recurrence were more likely to remain off OAT (HR 0.23 [95% CI 0.17\u20130.33]).
