4. Discussion:
Cause of AAFL: Table 1 shows 66.1% had undergone prior ablation for AF/typical AFL; 6.5% had a surgical correction for congenital heart disease; 15.2% had mitral/ aortic valve repair/replacement; 7.8% had undergone surgical MAZE procedure and the rest 7% with other cardiac interventions. This cohort is representative of the referral patterns seen in many centers that frequently deal with AAFL.
This is the largest cohort of patients who underwent the contemporary AAFL mapping and ablation practice. Ablation of AF begets more AAFL is the new norm.
