Prevalence of patent foramen ovale (PFO) is higher in patients with paradoxical embolism and associated with increased risk for recurrent thromboembolic events. By percutaneous closure of PFO, surgical closure or permanent oral anticoagulation can be avoided. So far, published series included different occluder systems and various indications and regimens of postprocedural anticoagulation. The aim of the present study was to evaluate the short- and long-term results after implantation of the Starflex occluder in patients with PFO using an intensified anticoagulation regimen. ⋯ Percutaneous closure of PFO in symptomatic patients by Starflex occluder represents an effective therapy with a low incidence of periinterventional complications and recurrent thromboembolism. However, thrombus formation at the occluder system may occur in some patients despite an aggressive anticoagulation regimen.
