Atrial mapping during pulmonary vein pacing to detect conduction gaps in a second pulmonary vein isolation procedure

ConclusionsP&M is a simple maneuver to identify the gaps in ablation lines around the PV. It remains efficacious in redo procedures despite the difficulties in localizing the ablation lines performed in the first procedure. The P&M maneuver reduced the radiofrequency time required to isolate the PV without compromising the efficacy.
