Does DEEP mapping improve specificity compared to LP mapping for identifying critical targets of VT ablation?
DEEP mapping offers higher specificity than LP mapping for identifying critical targets during VT ablation, driven by conduction velocity restitution in scar channels.
In this preliminary study, DEEP mapping was more specific than LP mapping for identifying the critical targets of VT ablation. The mechanism of DEEPs relates to conduction velocity restitution magnified by zigzag conduction within scar channels.
Jackson et al. (2015) studied this question.
