Implication

May support ablation for VT without structural heart disease; leaves open role in structural cases given small series.

Key Points

To assess the long-term clinical efficacy and safety of radiofrequency catheter ablation in patients with ventricular tachycardia, with and without underlying structural heart disease.
Evaluated 23 patients (9 females, mean age 49.1 ± 15.6 years) undergoing 30 radiofrequency catheter ablation procedures for monomorphic or polymorphic ventricular tachycardia.
Stratified outcomes between patients with structural heart disease (n=7; post-infarction, arrhythmogenic right ventricular dysplasia, corrected transposition) and without structural heart disease (n=16).
In patients without structural heart disease, catheter ablation eliminated or markedly suppressed arrhythmia in 11 of 16 patients (68.7%), with overall clinical benefit achieved in 14 of 16 patients (87.5%).
In patients with structural heart disease, sustained monomorphic ventricular tachycardia was eliminated with no recurrence during follow-up in 4 of 7 patients, alongside marked reduction in ICD shocks in complex post-infarct scar ablation.

Structured PICO

Does radiofrequency catheter ablation eliminate ventricular tachycardia in patients with and without structural heart disease?

Population

23 patients (9 females) aged 49.1 ± 15.6 years with ventricular tachycardia (7 with structural heart disease, 16 without structural heart disease)

Intervention

Radiofrequency catheter ablation

Outcome

Long-term elimination of ventricular tachycardia

Radiofrequency catheter ablation is highly effective for long-term elimination of ventricular tachycardia, serving as a permanent cure in patients without structural heart disease and an adjunctive therapy in those with structural heart disease.
