Predictors of VT recurrence during follow-up
Inducibility of >1 VT morphology, the presence of a large
endo/epicardial scar (>30%), LVEF < 30% and
impossibility of performing activation mapping during VT ablation were
associated with VT recurrence in univariate analysis (table 3). A Cox
proportional model was used for multivariate analysis and variables with
a p value ≤0.15 in univariate analysis were included in the model.
Baseline induction of >1 VT morphology was the only
independent predictor of VT recurrence in multivariate analysis (HR
12.05 IC 95% 1.60-90.79, p=0.016) (table 3).
