[Update Ventricular Tachycardia]

Idiopathic ventricular tachycardia: Frequent monomorphic premature ventricular contractions or non-sustained ventricular tachycardia without underlying structural heart disease is not a rare condition and may cause significant symptoms. A subgroup of patients develops IVT-associated cardiomyopathy. Current ESC guidelines recommend primary catheter ablation in symptomatic patients with right ventricular outflow tract IVT. Catheter ablation is also recommended in symptomatic patients with a left ventricular outflow tract (or other rare) origin, if antiarrhythmic drugs are ineffective or not desired.Ventricular tachycardia associated with structural heart disease: Scar-associated ventricular arrhythmias may cause sudden cardiac death in a variety of heart diseases. While ICD implantation has been shown to reduce mortality, repetitive ICD shocks impact on survival and quality of life. In a recent meta-analysis, both amiodarone and catheter ablation reduce the incidence of recurrent ICD shocks. Discontinuation of amiodarone due to side effects is common. Current ESC guidelines recommend both strategies (class 1 indication). Catheter ablation is also recommended in drug-resistant VT or electrical storm. A totally subcutaneous ICD is a novel option in patients not requiring pacing.
