Methods:
We conducted a retrospective analysis of patients >75 years of age undergoing index AF ablation between January 2010 and
March 2019 at our center. Major complications and efficacy, defined as
freedom from any atrial tachyarrhythmia (ATA) lasting ≥30 seconds after
one year of follow-up, were assessed in patients with index RF vs. CB
ablation. Predictors of ATA recurrence at 1 year follow-up were also
evaluated.
