Results:
In our cohort of 194 patients, the mean age was 78 + 3.1 years,
58.2% were men, and 39.4% had persistent AF. The mean left atrial (LA)
diameter was 4.5 + 0.7, while the mean
CHA2DS2-VASc score was 3.5 + 1.2.
The majority (n=149, 76.8%) underwent RF ablation. The incidence of
complications was similar in the two sub-groups (RF: 1.3% vs. CB:
2.2%, p=0.67). No significant difference in success rate at 1-year
follow-up was found between patients receiving RF vs. CB ablation
(59.7% vs. 66.7%, p=0.68). In a multivariable model adjusting for the
relevant covariates only LA size [HR=1.64, CI: 1.15-2.34,
p<0.01] was independently associated with ATA recurrence at
1year follow-up.
