Main findings
The main findings of this study were as follows: (1) AI-guided PVI could
reduce the frequency of ERATs more than CF-guided PVI in both the PAF
and non-PAF patients; (2) the number of PV reconnections in the second
CA session was significantly smaller in AI-guided PVI group than the
CF-guided PVI group; and (3) AI-guided PVI was independently associated
with the incidence of ERAT in addition to the sex, LA diameter and type
of AF.
