Why the study?
In some patients, epicardial connections connecting the right-sided pulmonary veins and right atrium preclude successful first-pass PVI, requiring identification and elimination to achieve complete isolation.

May identify treatable right PV-RA epicardial connections after failed first-pass PVI; leaves open routine coherent mapping use.
Coherent mapping is useful for identifying and evaluating epicardial connections between the right-sided pulmonary veins and right atrium to achieve complete pulmonary vein isolation.
Wada et al. (2022) studied this question.
