Multivariate Cox’s proportional hazards analysis showed age ≥ 55 years at the time of closure (OR 7.49, ) as the main risk factor for AF diagnosis on follow-up. Also, atherosclerotic cardiovascular disease (OR 2.99, ) and HATCH score ≥ 3 at the time of closure (OR 3.09, ) resulted risk factors for AF diagnosis on follow-up. AF, atrial fibrillation; ASCVD, atherosclerotic cardiovascular disease; BMI, body mass index; Fla, atrial flutter; L, left; R, right; TIA, transient ischemic attack.
