Does catheter ablation of ventricular tachycardia yield different outcomes in patients with dilated nonischemic cardiomyopathy compared to ischemic cardiomyopathy?
Complete elimination of all inducible VTs during ablation is associated with better long-term outcomes in patients with nonischemic dilated cardiomyopathy, who generally have worse long-term outcomes than those with ischemic cardiomyopathy.
Although the short-term success rates after VT ablation in NIDCM and ICM patients were similar, the long-term outcomes in NIDCM patients were significantly worse. Complete VT noninducibility at the end of the ablation is associated with beneficial long-term outcome in NIDCM. Pursuing compete elimination of all inducible VTs is desirable and may improve the long-term success in NIDCM.
