Catheter ablation of ventricular tachycardias emerged significantly as standard therapy in the past 20 years. In this review recent advances in catheter ablation of ventricular tachycardias are discussed. The authors first present in details the technical aspects of ablation strategies, main indications and contraindications of ventricular tachycardia ablation and the necessary pre- and postinterventional diagnostic tests. Outcome is also discussed in different forms of ventricular tachycardias in detail. The authors summarize the safety and efficacy of catheter ablation of ventricular arrhythmias. They recommend that ablation of ventricular tachycardias should be considered earlier in patients with and without structural heart disease.
