Up to 30% of patients could have very late recurrence of atrial fibrillation after catheter ablation, according to research highlighted at the recent Boston AF Symposium. Very late recurrence, which is when atrial fibrillation resumes more than one year after ablation, may be the result of age, gender, type of afib, and existence of other heart conditions. Persistent atrial fibrillation was found to be more likely to cause recurrence than paroxysmal atrial fibrillation.
