Key result
Paced electrogram feature analysis (PEFA) based ablation for scar-related ventricular tachycardia resulted in non-inducibility in 90% of patients and a 15% VT recurrence rate over 437.5 days.
Why the study?
The incremental benefit of scar-related VT ablation remains modest with frequent recurrent shocks and ATP, highlighting the need for improved ablation strategies.

Does PEFA-based VT ablation prevent VT recurrence in patients with scar-related VT?
PEFA-based VT ablation is a promising substrate-based strategy that achieved high rates of non-inducibility and low VT recurrence in patients with scar-related VT.
Crinion et al. (2019) conducted an observational in Scar-related ventricular tachycardia (n=20). Paced electrogram feature analysis (PEFA) based VT ablation was evaluated on VT recurrence. Paced electrogram feature analysis (PEFA) based ablation for scar-related ventricular tachycardia resulted in non-inducibility in 90% of patients and a 15% VT recurrence rate over 437.5 days.
