2018 AF Symposium: Kiss of Death for FIRM Mapping? The REAFFIRM Trial
In a late-breaking presentation, the interim results of the REAFFIRM trial were presented by Dr. John Hummel from the Ohio State University Wexner Medical Center.
FIRM stands for Focal impulse and rotor modulation (FIRM) and is used for mapping electrical signals of the heart.
The trial was intended to assess the safety and effectiveness of FIRM mapping used with conventional ablation (including PVI) versus a standard PVI procedure for the treatment of persistent atrial fibrillation.
REAFFIRM Trial Design
In a prospective multi-center trial, 350 patients with persistent or long-standing persistent A-Fib who had not had a previous ablation were randomized in a 1:1 fashion. The trial was designed to compare FIRM mapping used with standard catheter ablation (including PVI) versus PVI without use of FIRM mapping.
The non-FIRM ablation control group included…Continue reading this report->
