Event Description

This complaint is from a literature source.As reported in the literature publication entitled,¿ targeted ablation of ventricular tachycardia guided by wavefront discontinuities during sinus rhythm (pmid: 31533463).1 patient with scar-related ventricular tachycardia (vt) who underwent ablation procedure experienced transient phrenic nerve palsy was observed after epicardial ablation of a basal lateral substrate.The aim of this study prospectively assessed outcomes of vt ablation guided primarily by the targeting of deceleration zones (dz) identified by propagational analysis of ventricular activation during sinus rhythm.Methods: one hundred twenty patients (median age 65 years underwent 144 ablation procedures for scar-related vt.57% of patients had previous ablation and epicardial access was employed in 59% of cases patients with scar-related vt were prospectively enrolled in the university of chicago vt ablation registry between 2016 and 2018.Isochronal late activation maps annotated to the latest local electrogram deflection were created with high-density multielectrode mapping catheters.Targeted ablation of dz (>3 isochrones within 1cm radius) was performed, prioritizing later activated regions with maximal isochronal crowding.When possible, activation mapping of vt was performed, and successful ablation sites were compared with dz locations for mechanistic correlation.Patients were prospectively followed for vt recurrence and mortality.Bwi devices (catheter- thermocool) were used in this study.No devices specific information (including catalog and lot number) were provided in the article.
