First Dutch experience with percutaneous left atrial appendage transcatheter occlusion

Area of Science:

• Cardiology
• Medical Devices
• Interventional Cardiology

Background:

• Patients with atrial fibrillation (AF) face a heightened risk of thromboembolic stroke.
• Oral anticoagulation is effective but can be difficult to manage or contraindicated.
• Left atrial appendage (LAA) thrombi are common in nonrheumatic AF, making LAA occlusion a target for stroke prevention.

Purpose of the Study:

• To evaluate the feasibility of percutaneous transcatheter LAA occlusion as an alternative to oral anticoagulation.
• To assess the safety and tolerability of a novel LAA occlusion device.

Main Methods:

• Three patients underwent percutaneous transcatheter LAA occlusion implantation.
• Procedures were guided by intracardiac and transoesophageal echocardiography.
• No general anesthesia was used, and patients were monitored for long-term follow-up.

Main Results:

• LAA occlusion device implantation was successfully performed without major complications.
• The procedure was well-tolerated by all three patients.
• Patients were enrolled in a long-term follow-up study.

Conclusions:

• Transseptal percutaneous LAA occlusion is a feasible procedure.
• The role of LAA occlusion as an alternative to oral anticoagulation requires further investigation.
