Patent foramen ovale with complex anatomy: Comparison of two different devices (Amplatzer Septal Occluder device and Amplatzer PFO Occluder device 30/35)

摘要

Background: Patent foramen ovate (PFO) closure after a cryptogenic cerebral ischemic event is a routinely procedure. The most used device is Amplatzer (TM) PFO Occluder 25 mm, but PFOs with complex anatomy require larger device for closure. We compared Amplazer (TM) Septal Occluder (ASO) device versus Amplatzer (TM) PFO Occluder 30 or 35 mm (A-PFO 30/35) about:the safety of procedure and the presence of residual shunt during the follow-up.
