Delineation of conduction gaps of linear lesions during atrial fibrillation ablation using ultra-high-density mapping
Authors' conclusion
The entrances and exits of electrical conduction gaps were separated, especially in the roof region, indicating that epicardial conduction might contribute to gap formation.

Main finding
As reported in the abstract
Roof region (box) vs Bottom region (box): P = 0.022 · Right PV (PVI) vs Left PV (PVI): P = 0.201
Observational data: associations, not effects.
