Endocardial and epicardial mapping and catheter ablation of post myocardial infarction ventricular tachycardia: A substrate modification approach.
Ventricular tachycardia associated with prior myocardial infarction account for significant morbidity, mortality, and health care costs despite the favorable outcomes shown by ICD clinical trials. Catheter ablation has been increasingly used as an adjunctive therapy in the management of scar-related ventricular tachycardia. Novel technologies have facilitated the outcomes of current ablation strategies. Three-dimensional mapping systems have allowed identification of the scar substrate, its critical sites in the tachycardia circuit, and selection of ablation sites based on fairly precise electroanatomic substrate.
