Key result
OSCAR dual-snare framework enables controlled percutaneous retrieval of embolized atrial septal defect occluders.
Why the study?
Device embolization is an uncommon but important complication of transcatheter ASD closure, and percutaneous retrieval can be challenging when the occluder remains mobile or is unfavourably oriented.
Presents the OSCAR (Orientation–Stabilization–Capture–Alignment–Retrieval) educational framework utilizing a sequential dual-snare approach for controlled percutaneous retrieval of an embolized ASD occluder.
The OSCAR framework may aid controlled retrieval of embolized ASD occluders; leaves open the need for prospective validation before wider use.
Device embolization is an uncommon but important complication of transcatheter atrial septal defect (ASD) closure. Percutaneous retrieval can be challenging when the occluder remains mobile or is unfavourably oriented. We present a case-based educational framework, OSCAR (Orientation–Stabilization–Capture–Alignment–Retrieval), illustrating a sequential dual-snare approach to controlled retrieval.
