title: Ablation of ventricular arrhythmias.
abstract: Ventricular arrhythmias (VAs) commonly occur in patients with structural heart disease and may present as ventricular premature depolarizations (VPDs), monomorphic ventricular tachycardia (VT), or polymorphic VT/ventricular fibrillation. Idiopathic VAs can also occur in patients with normal hearts. This review explores the etiology, clinical presentation, and management strategies for different types of VAs. Medical and invasive treatment strategies are discussed, and different approaches to catheter ablation are outlined. While ablation of VPDs and idiopathic VT provides a cure for the majority of patients, investigation is ongoing to define the optimal ablation strategy for patients with scar-related VT.
