Abstract 17172: Pre Ablation Voltage Mapping Can Alter VT Inducibility

Abstract: Introduction: VT inducibility is often used to assess the efficacy of VT ablation. Sinus rhythm voltage maps (VMs) are used to guide ablation of VT substrate, but catheter manipulation may mechanically traumatize critical sites, altering VT inducibility. We prospectively evaluated the effect of VM on VT inducibility. Methods: Twenty-nine patients (mean age 62, 70% ischemic cardiomyopathy) with planned VT ablation underwent initial programmed electric st… Show more
