Pulmonary Vein Isolation as an End Point for Left Atrial Circumferential Ablation of Atrial Fibrillation

We sought to determine whether elimination of pulmonary vein (PV) arrhythmogenicity is necessary for the efficacy of left atrial circumferential ablation (LACA) for atrial fibrillation (AF). The PVs often provide triggers or drivers of AF. It has been shown that LACA is more effective than PV isolat...
