Ventricular Tachycardia: Past, Present & Future

Take home messages

  • Ventricular tachycardia (VT) is most commonly a re-entrant circuit sustained by channels of slow conduction in borderzone tissue between dense scar and healthy myocardium.
  • Catheter ablation is a guideline recommended therapy for patients with symptomatic monomorphic VT, refractory to antiarrhythmic drugs.
  • Recurrence remains common, reflecting limitations in mapping, ablation lesion creation/durability, and patient selection.
  • Earlier intervention, improved risk stratification, emerging ablation technologies and machine learning approaches may improve outcomes
