Major findings
The major findings of the present study were: (1) Most AF patients had
minimum to mild LVAs using the HDG (HD wave solution) regardless of an
enlarged LAD and LA volume. (2) There were no significant differences in
the max and mean DF values and %NP after the PVI between the patients
with and without recurrent AF/AT. (3) The LVAs, regardless of a minimum
to mild extent, were significantly indicated to be greater in the
patients with recurrent AF/AT than in those without. (4) The number of
high-DFs sites overlapping with LVAs was significantly greater in
patients with recurrent AF/AT than in those without. (5) The atrial
arrythmia freedom off AADs after the PVI was significantly lower in the
patients with high-DF sites overlapping with LVAs than in those without
during 11.6±0.8 months of follow-up.
