Key result
Radiofrequency ablation for ventricular tachycardia in ischaemic heart disease significantly reduced median ICD shocks per year from 1.1 to 0 (p < 0.0001).

Absolute Event Rate: 0% vs 1.1%
p-value: p=<0.0001
Radiofrequency ablation for ventricular tachycardia in ischemic heart disease significantly reduces the burden of ICD shocks, despite modest long-term freedom from recurrence.
Mørk et al. (2014) conducted a cohort in Ventricular tachycardia in ischaemic heart disease (n=90). Radiofrequency ablation (RFA) vs. Pre-ablation (baseline) was evaluated on Number of ICD shocks/year (p=<0.0001). Radiofrequency ablation for ventricular tachycardia in ischaemic heart disease significantly reduced median ICD shocks per year from 1.1 to 0 (p < 0.0001).
