AF Symposium 2015: Clues to Finding Drivers When Ablating for Persistent A-Fib

Pierre Jais MD
In my new report, Dr. Pierre Jais of the French Bordeaux/LIRYC group describes a research study of ablations performed on 50 patients with persistent A-Fib. He shares the insights he learned using the CardioInsight mapping system (ECGI) to map and ablate A-Fib signal drivers.
First, a little background. During an ablation procedure, A-Fib signals are mapped and lesions made to eliminate the signal drivers. After this initial effort, it is not uncommon for some arrhythmias signals to continue. So, another round of time-consuming mapping, analysis and diagnosis is needed.
Dr. Jais describes how he used the research data from the ECGI and learned how to anticipate the probable location of these additional A-Fib signals.
This is a very important clue for doctors and patients. It helps doctors spend less time mapping and ablating these additional sources of A-Fib signals. The benefit to the patient is a shorter ablation procedure time and fewer lesions (burns) to eliminate the A-Fib signals.
