Catheter ablation of ventricular tachycardia in postmyocardial in-farction
In contrast to ventricular tachycardia (VT) that occurs in the setting of a structurally normal heart, VT that occurs in patients with myocardial infarction carries an elevated risk for sudden cardiac death(SCD), and im-plantable cardioverter-defibrillators(ICDs)are the mai-nstay of therapy. In these individuals, catheter ablation may be used as adjunctive therapy to treat or prevent repetitive ICD therapies when antiarrhythmic drugs are ineffective or not desired. However, certain patients with frequent premature ventricular contrac- tions (PVCs) or VT and tachycardiomyopathy should be considered for ablation before ICD implantation because left ven-tricular function may improve, consequently decreasing the risk of SCD and obviating the need for an ICD.
