Single-Center Experience with Rotor Mapping and Ablation for Treatment of Atrial Fibrillation in 170 Patients1
This is a study consisting of 170 patients (mean age 59 yr, 79% men):
- 42% had prior failed ablations
- 37% AF was paroxysmal AF patients (PAF)
- 31% persistent AF patients (PeAF)
- 32% longstanding persistent AF patients (LPAF)
The follow-up period was 12 months.
- Right atrial sources were found in 84% of patients (mean 1.4/PT).
- Left atrial sources were found in 90% of patients (mean, 2.1/PT).
- AF acutely terminated in 58% (PAF), 37% (PeAF) and 18% (LPAF) of patients.
The location and distribution of rotors identified and long-term results were consistent with previously published results of FIRM-guided ablation.23
