High Density Mapping and Ablation of Concealed Low Voltage Activity Within Pulmonary Vein Antra Results in Improved Freedom from Atrial Fibrillation Compared to Pulmonary Vein Isolation Alone.

CLVS are commonly identified with HDM after PVI, likely representing vulnerabilities in antral lesion sets. Ablation of these targets appears to significantly improve freedom from AF compared to PVI alone.
