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).
