Letter by Berruezo et al regarding article, "Impact of local ablation on interconnected channels within ventricular scar: mechanistic implications for substrate modification".

BACKGROUND The extent to which channels within scar are interconnected is not known. The objective of the study was to evaluate the impact of local ablation of late potentials (LPs) on adjacent and remote areas of slow conduction with simultaneous multipolar mapping. METHODS AND RESULTS Analysis was performed on consecutive patients referred for ablation… CONTINUE READING
