EFFECT OF BASELINE ANTIARRHYTHMIC DRUG ON OUTCOMES WITH ABLATION IN ISCHEMIC VENTRICULAR TACHYCARDIA: A VANISH SUBSTUDY

摘要

BACKGROUND: The interaction of antiarrhythmic drugs with catheter ablation for ventricular tachycardia has not been previously described. Using data from the VANISH study, we sought to examine the effect of these treatments by antiarrhythmic drug prescribed at baseline. METHODS: All patients enrolled in the VANISH study were included (n=259). Analysis was conducted based on whether patients had recurrent VT refractory to Amio as compared to sotalol. Baseline characteristics and outcomes were compared between the two groups. Outcomes were death, VT storm or appropriate ICD shock.
