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.
