Prospective Evaluation of Biophysical Parameters as Long-term Predictors of Pulmonary Vein Isolation

The settings used during ablation will be for both groups: 15W, unipolar; 5ml/min baseline irrigation, 35ml/min irrigation during inflation/RF application; 55°C target electrode temperature; RF application time 60s for anterior electrodes, 20s for posterior electrodes. The catheter insertion in Pulmonary vein and ablation workflow will be different for two groups.
