Key result
Catheter ablation eliminates ~67% of non-ischemic sustained VT without long-term recurrence.
Why the study?
Long-term outcomes and optimal ablation strategies for ventricular tachycardia in patients with non-ischemic underlying heart disease remain unclear.
Population
8 patients with non-ischemic heart disease and 12 sustained VTs
Comparison
Different VT origin sites and ablation modes
Design
Observational study
Follow-up
31.2 +/- 6.5 months

May support ablation feasibility in non-ischemic VT; leaves open efficacy confirmation in randomized trials.

Chinushi et al. (1996) conducted an observational in Non-ischemic sustained ventricular tachycardia with underlying heart disease (n=8). Radiofrequency catheter ablation was evaluated on Successful ablation without recurrence during follow-up. Radiofrequency catheter ablation successfully eliminated 66.7% (8 of 12) of non-ischemic sustained ventricular tachycardias, with no recurrences during a mean follow-up of 31.2 months.
