Figure 1 Two ablation strategies for high-burden paroxysmal atrial fibrillation. The left panel displays radiofrequency applications to the pulmonary vein antrum alone on the reconstructed left atrium map in the posteroanterior view. The right panel illustrates additional ablation at the mitral isthmus (MI). Ablation strategy involving pulmonary vein isolation (PVI) alone is labeled “2C”, while PVI combined with MI ablation is labeled “2C1L”.
