Ten years of experience with closure of persistent foramen ovale: patient characteristics and outcomes.
Optimal management of patients with persistent foramen ovale (PFO) following cryptogenic stroke or transient ischemic attack (TIA) suspected for paradoxical embolic events is still unclear. PFO closure has the potential benefit of preventing recurrent embolic events and avoiding serious bleeding resulting from long-term anticoagulation. Despite the widespread usage of closure devices, no randomized trial supports the general percutaneous closure approach. In addition, only mid-term, but not long-term, outcomes have been reported until now. The aim of the study is to assess clinical characteristics and long-term clinical outcome of patients undergoing percutaneous PFO closure. ⋯ This "all-comers" population documents the safety of percutaneous PFO closure. The cardiovascular event rate is slightly lower (0.26 per 100 patient years) compared to the recently published randomized trials and maintained persistently low rate for more than 8 years.
