Ablation of Ventricular Tachycardia and Ventricular Extrasystolia

The ablation of ventricular arrhythmias has become an established therapy. This therapy is in most circumstances superior to an exclusive drug therapy because it is dealing with the arrhythmogene substrate. Moreover its complication rate is less performed in experienced centres. The development of three-dimensional mapping systems and the use of specific ablation catheters has guided the ablation of ventricular tachycardia or ventricular extrasystolia towards a more sufficient and safer ablation approach. There is an ongoing discussion about the right moment of ablation especially in patients with structural heart disease with preserved left ventricular function as an alternative treatment instead of a lifelong ICD implantation.
