AF Symposium 2015: Going Beyond PVI With ECGI Mapping and Ablation Techniques
ECGI is changing everything. Instead of potentials and CFAEs, EPs will focus on ablating drivers (rotors and foci). Prof. Michel Haïssaguerre of the French Bordeaux group/LIRYC gave a presentation on the changing world of catheter ablation using Non-Invasive Electrocardiographic Imaging, or ECGI (from CardioInsight), a radically new and innovative mapping and ablation system.
The system automatically detects rotors and foci and computes them into a “Cumulative Map” or movie. These driver regions are ranked, based on statistical prevalence. They are displayed in statistical density maps which define the ablation road map.
Ablation using ECGI results in a dramatic decrease of RF burns needed to produce A-Fib ‘termination’.
Dr. Haïssaguerre showed slides where he ablated driver regions which then transformed rapid complex A-Fib signals into slower organized signals.
