Abstract 2022: Feasibility of Dynamic Substrate Mapping: Insights from an Animal Infarction Model and Comparison with Bipolar Voltage Mapping in Patients
Abstract:Background:
Different substrate based ablation strategies have been developed for ablation of ventricular tachycardia (VT) after myocardial infarction (MI). We investigated the “Dynamic Substrate Mapping (DSM)”, a tool integrated into the noncontact mapping (NCM) system.
Methods:
An electrophysiologic study (EPS) was performed 96 ± 10 days after experimental anteroseptal MI in 19 female sheep. Scar was defined by NCM during sinus rhythm. The area of sca… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
