Prevention of stroke by percutaneous left atrial appendage closure: short term follow-up
Insights
Left atrial appendage (LAA) closure using the PLAATO-device shows promise for preventing stroke in atrial fibrillation (AF) patients. This minimally invasive technique resulted in zero thrombo-embolic events over two years in preliminary studies.
Area of Science:
- Cardiology
- Medical Devices
- Interventional Procedures
Background:
- Atrial fibrillation (AF) poses a significant stroke risk, often managed with oral anticoagulation.
- Left atrial appendage (LAA) closure is an emerging alternative for stroke prevention in AF patients.
- The PLAATO-device offers a percutaneous approach to LAA closure.
Discussion:
- Percutaneous LAA closure with the PLAATO-device demonstrated preliminary clinical efficacy in preventing thrombo-embolic events.
- No thrombo-embolic events were observed in patients within a 2-year follow-up period post-procedure.
- This suggests LAA closure is a viable option for AF patients intolerant to or failing oral anticoagulation.
Key Insights:
- Successful percutaneous LAA closure using the PLAATO-device.
- Absence of thrombo-embolic events in patients over a 2-year follow-up.
- Potential alternative stroke prevention strategy for specific AF patient populations.
Outlook:
- Further clinical trials are warranted to confirm the long-term efficacy and safety of PLAATO-device LAA closure.
- LAA closure may become a standard treatment option for AF patients with contraindications to anticoagulation.
- Advancements in device technology could further enhance the applicability and success rates of LAA closure.
Abstract:
Preliminary studies suggest that left atrial appendage (LAA) closure might be beneficial in the prevention of stroke in patients with atrial fibrillation (AF). We evaluated the preliminary clinical efficacy of percutaneous LAA closure using the PLAATO-device (ev3 Endovascular, Inc., North Plymouth, MN) and found that none of the patients suffered from thrombo-embolic events within a time period of 2 years after successful LAA closure. Therefore, we believe that percutaneous closure of the LAA might be a valuable technique for AF patients with contra-indications for or failure of oral anticoagulation to prevent thrombo-embolic events.
