Evoked delayed potential ablation for post-myocardial infarction ventricular tachycardia: results from a large prospective multicentre study
- Prospective cohort study
- multicentre
Authors' conclusion
In a large multicentre prospective cohort of patients with post-MI VT, EDP ablation resulted in good long-term outcomes. Importantly, VT recurrence rates did not differ among centres with and without prior experience in EDP ablation, indicating that this approach can be easily reproduced by operators previously not familiar with the technique.
Study context
