Rotor mapping and Ablation in Redo Cases of Persistent Atrial Fibrillation Procedural and Follow-up Data1
This is a study consisting of 54 patients with persistent AF, all of which had failed a prior conventional ablation (a mean of 1.4 prior ablations).
The follow-up period was 12 months.
The location and distribution of rotors identified and long-term results were consistent with previously published results of FIRM-guided ablation.234
- Most rotors were outside of the areas that would normally be targeted with traditional ablation.
- The presence of RA rotors was seen in over 50% of patients, which reinforces the importance of the RA.
- AF acutely terminated in only 5 patients, therefore reinforcing the value of rotor elimination as an acute endpoint.
