AimsThe interatrial septal thickness (IAST) reflects the changes of atrial wall in patients with fibrillation (AF). Complex fractionated electrograms (CFAEs) were consistently positioned on septum, especially remodelled left atrium (LA). We sought to characterize relationship between IAST and LA CFAE area, as well acute procedural clinical outcomes catheter ablation persistent AF patients.
