Summary
A novel ŌNŌ retrieval system successfully removed a dislodged Watchman FLX left atrial appendage device. This percutaneous approach offers a safer alternative to surgical removal for this rare complication.
Area of Science:
- Cardiovascular Interventions
- Medical Device Retrieval
Background:
- Left atrial appendage occlusion devices, such as the Watchman FLX, are used to prevent stroke in patients with atrial fibrillation.
- Device embolization is a rare but serious complication requiring intervention.
Observation:
- A case report detailing the successful retrieval of a significantly dislodged Watchman FLX device using the novel ŌNŌ retrieval system.
- The procedure involved advancing the ŌNŌ system and using specialized forceps and a basket to dislodge the device.
Findings:
- The ŌNŌ retrieval system facilitated the percutaneous removal of the embolized Watchman FLX device.
- The retrieval was achieved without reported complications such as device embolization, left atrial appendage avulsion, or pericardial effusion.
Implications:
- Percutaneous retrieval with the ŌNŌ system may represent a safer alternative to surgical intervention for dislodged left atrial appendage occlusion devices.
- This technique could potentially reduce morbidity and mortality associated with managing this complication.
