Prevalence of patent foramen ovale (PFO) with detectable right-to-left shunt is higher in young adults with transient ischemic attack (TIA) and stroke compared to the general population. So far, published series included different occluder systems, various indications and regimens of postprocedural anticoagulation. In our experience, occluder systems may be associated with an increased prevalence of thrombus formation, which has also reported by other groups. The aim of the present study was to evaluate the follow-up results after implantation of the Amplatzer® occluder in patients with PFO using a consistent anticoagulation regimen. ⋯ Percutaneous closure of PFO in symptomatic patients by Amplatzer® occluder represents an effective therapy with a low incidence of peri-interventional complications and recurrent thromboembolism. Thrombus formations on the occluder system were not detected in this cohort.
