Abstract
The management of ventricular tachycardias (VT), which are often associated with severe cardiac disease, is achallenging clinical task. The structural damage to the myocardium associated with cardiomyopathy is crucial to the occurrence of VT and plays afundamental role in arrhythmia mechanisms. The goal of catheter ablation is to develop an accurate understanding of the patient-specific arrhythmia mechanism as a first procedural step. As a second step, the ventricular areas that maintain the arrhythmia mechanism can be ablated and thereby electrically inactivated. Catheter ablation thereby enables causal therapy of VT by modifying the areas of the affected myocardium in such away that VT can no longer be triggered. The procedure is an effective treatment option for affected patients.
