L'ablazione con radiofrequenza della tachycardia ventricolare nel paziente con cardiomiopatia dilatativa

The incidence of drug refractory ventricular tachycardia recurrences in patients with dilated cardiomyopathy can be significantly reduced by radiofrequency catheter ablation. The recent introduction of three-dimensional electroanatomical mapping systems improved the success rate and extended the indication to patients with unstable and/or multiple ventricular tachycardias. The present article summarizes the indications, the mapping techniques and the most recent results of catheter ablation of ventricular tachycardias in the setting of dilated cardiomyopathy.
