Flutter Localized to the Anterior Left Atrium After Catheter Ablation of Atrial Fibrillation

Abstract

Organized arrhythmias occurring after AF ablation can be due to reentrant circuits localized to the anterior LA, predominantly in females with chronic AF, structural heart disease, and abnormal atrial conduction. They are characterized by a distinctive surface ECG and highly responsive to RF ablation at the slow conduction area.
