Predictors of extensive LVAs
Because the extent of LVA spreading after initial PVI might contribute
significantly to clinical outcomes, we performed additional analyses of
factors that predict extensive LVAs. Univariate analysis revealed that
advanced age, female, lower BMI, longer AF duration, higher
CHA2DS2-VASC score, lower renal
function, and large LAD were significant predictors for extensive LVAs
(Table 3). After multivariate analysis, female, low BMI, and large LAD
were considered to be independent factors associated with extensive LVAs
(Table 4).
