Comparison of Voltage Map-Guided Left Atrial Anterior Wall Ablation Versus Left Lateral Mitral Isthmus Ablation in Patients With Persistent Atrial Fibrillation

Study Questions:

Is mitral isthmus (MI) block achieved more effectively by voltage-guided left atrial anterior wall (LAAW) radiofrequency ablation (RFA) than by left lateral mitral isthmus (LLMI) ablation?
