Introduction
Several studies have demonstrated the efficacy of radiofrequency catheter ablation as an adjunctive therapy for selected patients with structural heart disease (SHD) and drug-resistant ventricular tachycardia (VT)1,2. Different ablation strategies have been proposed, and their outcomes varied across clinical trials3–9. Generally, the ideal endpoint of VT ablation in patients with SHD is non-inducibility of VT at the end of the ablation procedure10–12. Several retrospective comparative studies and meta-analysis have demonstrated that patients in whom VT cannot be induced at the conclusion of an ablation have a favorable outcome10–15. However, these studies have been limited because they lack data of patients who did not undergo programmed electrical stimulation (PES) at the end of the ablation procedure and data on the long-term follow-up of those patients. To answer this important clinical real-world question, we aimed to evaluate details and outcomes of patients who did not undergo PES at the end of the ablation procedure through our single-center experience.
