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).
