| Description
| - Complex fractionated atrial electrograms (CFAE) may provide a target for ablation of persistent atrial fibrillation (AF). This study evaluated relationship between the automatically detected CFAE in the atria and the sites of long-standing persistent AF termination during ablation. Methods: Fifty consecutive patients underwent a stepwise ablation for long-standing persistent AF. Left atrial (LA), right atrial (RA), and coronary sinus (CS) electroanatomic maps with automatically detected CFAE were obtained before ablation. Stepwise ablation with the ideal endpoint of sinus rhythm restoration was subsequently performed using plain electroanatomic maps. The relationship between CFAE sites and AF termination sites was retrospectively analyzed in 38 patients in whom ablation terminated AF. Results: There were 70 LA CFAE sites, 48 RA CFAE sites, and 20 CS CFAE sites found in 35 (92 %), 30 (79 %), and 19 (50 %) patients, respectively. Mean distance between the AF termination site and the closest CFAE site was 21.7+-17 mm. Distance between the AF termination site and the closest CFAE site <= 10, or 11-20 mm was found in 11 (29 %), and 10 (26 %) patients, respectively. AF termination was achieved after ablation of 85 +- 28 % LA CFAE sites, 58+-28 % CS CFAE sites, and 16 +- 33 % RA CFAE sites. Conclusions: Although the CFAE sites and AF termination sites did not directly correlate in a majority of the patients, most of the LA CFAE sites and more than half of the CS CFAE sites had been targeted before AF termination, suggesting rather cumulative effect of CFAE ablation.
