Evoked delayed potential ablation for post-myocardial infarction ventricular tachycardia: results from a large prospective multicentre study.

ABSTRACT:

Aims

The optimal substrate ablation approach for post-myocardial infarction (MI) ventricular tachycardia (VT) is unknown. Proposed ablation targets are prone to individual interpretation making the ablation outcome potentially operator dependent. Evoked delayed potentials (EDPs) are a well-defined target. Evoked delayed potential ablation was effective in preventing post-MI VT recurrence in a prior study. The aims of this study were to assess long-term outcomes of EDP ablation in a large multicentre cohort of post-MI patients and to compare ablation outcomes between centres with and without prior experience in EDP ablation.

Methods and results

Patients with post-MI VT undergoing ablation in one centre performing EDP ablation since 2013 and five centres without prior experien
