Modification of Electrophysiological Properties of Pulmonary Veins and Adjacent Left Atrial Tissue by Radiofrequency Thermal Balloon Circumferential Ablation around the Pulmonary Vein Ostia: Correlation with Non-recurrence of Atrial Fibrillation

Conclusions: Circumferential ablation around the PV ostia using the RBC is effective in the treatment of AF even in a single session, and AF recurrence may well be predicted by precisely measuring the amplitude of remaining PV-LA potentials.
