Structured PICO

Is epicardial percutaneous ablation a safe and effective approach for preventing ventricular tachycardia recurrence?

P
Population
218 patients undergoing epicardial subxyphoid access for ventricular tachycardia (VT) ablation across 6 European centers, including patients with coronary artery disease (n=85), idiopathic dilated cardiomyopathy (n=67), arrhythmogenic right ventricular dysplasia/cardiomyopathy (n=13), hypertrophic cardiomyopathy (n=5), and absence of structural heart disease (n=48).
I
Intervention
Epicardial percutaneous ablation via subxyphoid access (attempted as first-line treatment in 35.8% of patients)
O
Outcome
Acute prevention of VT inducibility and VT recurrencehard clinical

Epicardial ablation for ventricular tachycardia is a feasible approach with acceptable risk, achieving acute non-inducibility in over 70% of patients, supporting its consideration as a first-line strategy in selected cases.

Bella et al. (2011) conducted an observational in Ventricular Tachycardia (n=218). Epicardial percutaneous ablation was evaluated on Acute prevention of VT inducibility. Epicardial percutaneous ablation for ventricular tachycardia achieved acute prevention of VT inducibility in 71.6% of patients, with a 31.4% recurrence rate over a mean follow-up of 17.3 months.
