Key result
Radiofrequency catheter ablation of ventricular tachycardia achieved 83% procedural success, with successful ablation reducing VT recurrence to 19% vs 64% in unsuccessful cases (P<0.001).

Effect estimate: 75% relative risk reduction
Absolute Event Rate: 19% vs 64%
p-value: p=< 0.001
Radiofrequency catheter ablation of drug-refractory VT has a high procedural success rate (83%) and significantly reduces long-term VT recurrence, supporting its use as an effective treatment modality.
Burg et al. (2002) conducted a cohort in drug-refractory ventricular tachycardia (n=151). Radiofrequency catheter ablation vs. Nonsuccessfully ablated patients was evaluated on VT recurrences (75% relative risk reduction, p=< 0.001). Radiofrequency catheter ablation of ventricular tachycardia achieved 83% procedural success, with successful ablation reducing VT recurrence to 19% vs 64% in unsuccessful cases (P<0.001).
