Structured PICO
Where are successful ablation sites located relative to the scar border zone defined by substrate mapping for ventricular tachycardia post-myocardial infarction?

Successful ablation sites for post-MI VT are not exclusively confined to the scar border zone, highlighting the need for comprehensive mapping.
Abstract
Successful ablation sites of hemodynamically stable, monomorphic VTs post-MI are often located in the scar border zone as defined by substrate voltage mapping. However, in a sizable minority, ablation sites are located within endocardial scar, epicardially, and even in normal myocardium.
