Recurrent Ischemic Stroke/Transient Ischemic Attack After Patent Foramen Ovale Closure: A cohort study

Patent foramen ovale (PFO) has been associated with ischemic stroke and transient ischemic attack (TIA). Guidelines recommend PFO closure for stroke prevention in selected patients, but the risk of recurrent stroke remains high compared to the background population. We aimed to evaluate the causes of recurrent stroke/TIA and post-interventional complications in patients after PFO closure.
