Randomized Controlled Trial
Substrate modification or ventricular tachycardia induction, mapping, and ablation as the first step? A randomized study.
The role and optimal sequence of ventricular tachycardia (VT) induction, mapping, and ablation when combined with substrate modification is unclear. ⋯ VT induction and mapping before substrate ablation prolongs the procedure, radiation exposure, and the need for electrical cardioversion without improving acute results and long-term ablation outcomes.
