About this trial
Patent foramen ovale (PFO) is associated with an increased risk of stroke. PFO-closure was effective in preventing stroke in young stroke patients less than age 60 presented as an embolic stroke of undetermined source (ESUS). However, the benefit of PFO-closure in elderly ESUS patients is not clear. The investigators designed this prospective register-based observational study to verify the efficacy of PFO-closure in elderly ESUS patients with high-risk PFO, older than 60 years

Patients with ischemic stroke at the vascular territory with significant stenosis
Patients with high risk cardioembolic stroke detected from EKG, Holter monitoring or echocardiography
