Article Synopsis
- The study evaluates Directed Graph Mapping (DGM) as a new method for identifying mechanisms and crucial components in ventricular tachycardia (VT) ablation, comparing its accuracy to traditional mapping techniques and an automated conduction mapping tool.
- Results showed strong agreement between DGM and the gold standard traditional mapping (TM), with a kappa value of 0.79, indicating DGM’s effectiveness in discerning VT mechanisms and circuits.
- DGM and the automated tool correctly identified the critical VT isthmus in 89% of re-entrant cases, demonstrating DGM's potential as a faster, reliable option for VT analysis.
Article Synopsis
- Accurate annotation of local activation time is essential for assessing the functional substrate of ventricular tachycardia (VT), but traditional mapping systems limit the observation of late potentials (LPs) to 490-500 milliseconds.
- A novel retrospective window of interest (rWOI) was used in this study to capture all diastolic potentials during VT substrate mapping, revealing that 65% of cases had LPs beyond standard limits.
- The study found two main activation patterns in the VT substrate, identified a new marker for critical sites, and suggested future mapping systems should extend their windows to include important late potentials for better assessment.
Objectives: This study sought to describe the utility of automated conduction velocity mapping (ACVM) in ventricular tachycardia (VT) ablation.
Background: Identification of areas of slowed conduction velocity (CV) is critical to our understanding of VT circuits and their underlying substrate. Recently, an ACVM called Coherent Mapping (Biosense Webster Inc) has been developed for atrial mapping.
