May support substrate-based VT ablation in structural heart disease; leaves open need for randomized confirmation.
Substrate-based ablation strategies, aided by high-density multipolar mapping and cardiac imaging, are increasingly used and effective for treating ventricular tachycardia in patients with structural heart disease.
Kitamura et al. (2019) conducted a review in Ventricular tachycardia in patients with structural heart disease. Substrate mapping and ablation vs. Conventional activation/entrainment mapping and ablation was evaluated. Substrate-based ablation for ventricular tachycardia in patients with structural heart disease yields a recurrence-free rate of 54% to 91%, showing comparable or superior outcomes to conventional ablation.
