Percutaneous Closure of Patent Foramen Ovale in Patients with Anatomical and Clinical High-Risk Characteristics: Long-Term Efficacy and Safety

Abstract

Our study suggests that transcatheter PFO closure is a safe procedure even in a selected population of high-risk patients, presenting satisfactory efficacy and safety. The presence of a prominent EV alone or with ASA correlates positively with the occurrence of residual shunt.
