2017 AF Symposium: FIRM Rotor Mapping System During Live Ablation
In a live case from the 2017 AF Symposium, Dr. David Wilber from Loyola University Medical Center showed how he uses the Topera FIRM rotor mapping system to identify rotors in conjunction with a PVI. (‘FIRM’ stands for Focal Impulse and Rotor Modulation.)
Dr. Wilber described how he first does voltage mapping while the patient is in normal sinus rhythm. He started in the right atrium, then moved to the left; he used the FIRM system to map where rotors were coming from. (In patients with persistent A-Fib, he typically finds as many as 4-8 rotors.) He mapped and ablated until there were no more rotors.
Only after using the FIRM system did he do a Pulmonary Vein ablation…Continue reading my report.
