Transcatheter closure of patent foramen ovale with radiofrequency: Acute and intermediate term results in 144 patients

Currently available devices for transcatheter closure of patent foramen ovale (PFO) which rely on a permanent implant have limitations, including late complications. The study objective was to evaluate the safety, feasibility, and effectiveness of the PFx™ Closure System, the first transcatheter technique for PFO closure without an implantable device.
