Insights
Percutaneous left atrial appendage (LAA) occlusion is a treatment for stroke risk in atrial fibrillation. This report details successful retrieval of dislodged LAA devices using a transseptal approach, avoiding complications.
Area of Science:
- Cardiology
- Interventional Cardiology
- Medical Device Technology
Background:
- Atrial fibrillation (AF) patients at high risk for embolic stroke often cannot use oral anticoagulation.
- Percutaneous left atrial appendage (LAA) occlusion offers an alternative stroke prevention strategy.
- Complications, such as device embolization, can occur during LAA occlusion procedures.
Observation:
- Two cases of dislodged LAA occlusion devices were observed.
- One device was found freely mobile within the left atrium.
- The second device became entrapped within the mitral valve leaflets.
Findings:
- Both dislodged LAA occlusion devices were successfully retrieved.
- Retrieval was achieved using a transseptal approach.
- The retrieval procedures were completed without any reported complications.
Implications:
- The transseptal approach is a safe and effective method for managing dislodged LAA occlusion devices.
- This technique offers a viable solution for potentially serious procedural complications.
- Successful device retrieval can prevent further adverse events in patients undergoing LAA occlusion.
Abstract:
Percutaneous left atrial appendage (LAA) occlusion is a promising treatment option in patients with atrial fibrillation who have a high risk of embolic stroke and are not eligible for chronic oral anticoagulation therapy. This procedure, however, can induce several complications. Device embolization can result in a serious situation, requiring immediate and safe device removal. We report two cases in which dislodged LAA occlusion devices were flitting in the left atrium or entrapped in the mitral valve leaflets and were successfully retrieved through a transseptal approach without complications.
