Abstract
Ventricular arrhythmias arise from complex electroanatomical substrates in patients with structural heart disease. There have been significant advancements in technologies and techniques for ventricular tachycardia catheter ablation. A systematic approach to mapping and ablation is paramount, and catheter ablation has shifted to be a potential first-line therapy for patients needing early intervention, particularly for those with post-infarction arrhythmias. Furthermore, imaging integration, coupled with a systematic, detailed substrate characterization, has shown promise and provides a safe and effective approach for long-term arrhythmia control.
