AF in HD patients
Takigawa et al. reported the AF recurrence free rate at one year after
the first RFA session for PAF in HD patients was 42.3%, and the
one-year outcome after the final ablation was 64.7%.3In non-HD patients, it was 73.2% after the first session and 90.4%
after the final ablation.3 Our results after the first
ablation session for PAF were better than those reported by this
previous study. One of the potential reasons could be that a non-contact
force catheter was used in the aforementioned study. In the present
research, we started using contact force catheters since 2016; this
might be the reason for the AF recurrence in the previous study.
In our report, Arctic Front Advance or Arctic Front Advance PRO was used
for CBA. The previously reported freedom from AF in the
second-generation CBA (Arctic Front Advance) was better than that in the
first-generation CBA (Arctic Front) at 15 months (90% in second
generation vs 64% in the first generation).13Recently, a report that published on using CBA for patients with HD
found that the freedom from AF at 12 months was
79%.14 Our result also supported that the freedom
from AF in patients with HD after CBA might be better than RFA. Our
report is the first to include PAF, PeAF, and LSAF. Our outcome was the
composite endpoint of the recurrence of any ATA and the use of an AAD
which was different from the previous report. 14Furthermore, our report is the first report which revealed that freedom
from any ATA was statistically better in the CBA group than in the RFA
group among HD patients with an AAD.
