Joshua D. Moss, MD, FHRS, of University of California, San Francisco is joined by guests Thomas A Dewland, MD, FHRS, of University of California, San Francisco, and Nathaniel Steiger, MD, of Brigham and Women's Hospital to discuss Utility and Limitations of Ablation Index for Guiding Therapy in Ventricular Myocardium. The Ablation Index (AI) has limited value for guiding ablation in ventricular myocardium, particularly scar. This may be related to small proportional significance of application duration and complex tissue architecture.
