Why the study?
Even after two pulmonary vein isolation procedures, some patients suffer from atrial fibrillation recurrences, but characteristics identifying these patients remain unclear.

May refine risk stratification before repeat PVI; hypothesis-generating in this observational cohort and requires prospective validation.
What patient characteristics predict atrial fibrillation recurrence after two pulmonary vein isolation procedures?
Recurrence of atrial fibrillation after two pulmonary vein isolation procedures is associated with more advanced underlying disease, including heart failure, lower eGFR, and non-paroxysmal AF.
