Idiopathic Outflow Tract Ventricular Arrhythmia Ablation: Pearls and Pitfalls

Idiopathic ventricular arrhythmias (VAs) are comprised of ventricular premature depolarisations, non-sustained ventricular tachycardia (VT)and rarely sustained VT, and these typically occur in the absence of structural heart disease. In general, idiopathic VAs tend to have a benign prognosis, although a high burden of VAs can result in left ventricular (LV) systolic dysfunction and cardiomyopathy and, rarely, outflow tract (OT) VAs can serve as a trigger for idiopathic VF.
