Major finding
In this study, a composite outcome of a documented recurrence of any ATA or a prescription of an AAD in the CBA group was not statistically different from that in the RFA group. However, freedom from any ATA with an AAD was statistically better in the CBA group than in the RFA group. Although procedure-related complications were not different between the two groups, the procedure time was obviously shorter in the CBA group than in the RFA group. To our knowledge, this is the first study to explore the value of CBA for AF in HD patients.
