VT ablation evolves from last-resort to preemptive therapy with improved success driven by technological advances.
This review highlights the technological and conceptual evolution of VT ablation in structural heart disease, emphasizing its shift toward a preemptive strategy.
May inform earlier VT ablation consideration in structural heart disease; leaves open need for confirmatory RCTs before practice shifts.
The field of catheter ablation of VT has evolved conceptually and technologically over the past three decades. From the fundamental understanding of the reentrant mechanism in scar‐mediated VT to the advent and routine implementation of electroanatomic mapping, catheter ablation has emerged from a palliative last‐resort therapy to a more preemptive strategy for patients at risk for arrhythmia recurrence. An increasing utilization of pre‐procedural imaging, high‐density mapping, epicardial access, and more extensive ablation strategies have all contributed to improved clinical success. Advances in ablation technology and randomized trials are needed to build upon the progress in this growing field as sudden cardiac death from ventricular tachyarrhythmia continues to be the one of leading causes of death throughout the world.

Roderick Tung (2014) conducted a review in Ventricular tachycardia in structural heart disease. Catheter ablation was evaluated. Catheter ablation for ventricular tachycardia has evolved from a palliative last-resort therapy to a preemptive strategy, with improved clinical success driven by technological and conceptual advances.
