VISITAG Data
A total of 1316 ablation points in 20 patients (n=10 for FTI, n=10 for
TAI, Table 3) were analyzed. The number of RF application of points
(VisiTag) were unchanged between FTI and TAI in each PV (Table 3). There
was no significant difference in CFs between FTI and TAI in all segments
except for RPV posterior and bottom. FTI values in most anatomical
segments decreased in TAI versus FTI whereas RF power increased in TAI.
The impedance drop was also comparable between FAI and TAI in all
regions, except for the LPV anterior segment. RF application time per
lesion significantly decreased in TAI compared to FTI. These suggest
that AI-monitored RF application safely allows higher power and shorter
duration of RF energy application per VisiTag point (Table 3).
