Abstract :
Extrapulmonary vein focal sources have been recognized as the source of atrial fibrillation in some cases, and empiric electric
isolation of the left atrial appendage has been proposed for long-standing persistent atrial fibrillation by some. Here, we present
a case of redo ablation of long-standing persistent atrial fibrillation in which the left atrial appendage played a key role in
maintaining AF during ablation, and atrial fibrillation was terminated by electrical isolation of the LAA. During the ablation, a
rare phenomenon of half of the atria in atrial fibrillation while the other half of the atria in atrial flutter was seen.
