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.
