The 5-year success rates in the large Hamburg series were 20% and 45% after single and multiple ablation procedures, respectively. Success rates were far better in patients with a history of less than 2 years of persistent AF than in those who were arrhythmic for longer (J. Am. Coll. Cardiol. 2012;60:1921-9).
