DEEP Substrate Mapping Versus Activation Mapping for VT

💬

In plain words

What the trial is, and whether it could suit you

Substrate-based DEEP mapping and activation mapping are two of the main techniques used for guiding ventricular tachycardia (VT) ablation. There is no data comparing directly the extent of applicability, procedural results, and the long-term outcomes between the two mapping strategies.This randomized clinical trial aims to test whether activation mapping is superior to DEEP mapping to reduce ventricular tachycardia recurrence. The primary endpoint of the study is to compare recurrence-free survival rate of ventricular tachycardia at 12 months and procedural feasibility of substrate-based DEEP mapping versus activation mapping for VT ablation.
