Editorial commentary: Indications for catheter ablation of ventricular tachycardia in the modern era

The types of patients with structural heart disease (SHD) undergoing catheter ablation for ventricular tachycardia (VT) have changed dramatically over the past 20 years. In the past, most patients undergoing ablation had coronary artery disease (CAD) and presented with recurrent, slow, hemodynamically stable VT remote after a large transmural myocardial infarction (MI). As ablation techniques, mapping systems, therapies for advanced heart failure (HF), and experience have improved, more patients undergoing ablation for VT have hemodynamically unstable VTs commonly of multiple morphologies causing multiple implantable defibrillator (ICD) therapies, diffuse myocardial scar, and severe left ventricular dysfunction with refractory HF requiring support with a ventricular assist device.
