A new left atrial appendage occluder (Lifetech LAmbre Device) for stroke prevention in atrial fibrillation

Area of Science:

• Cardiology
• Medical Devices
• Interventional Procedures

Background:

• Non-valvular atrial fibrillation (AF) is a prevalent arrhythmia linked to ischemic stroke.
• Percutaneous left atrial appendage (LAA) closure is a growing intervention for AF patients at high risk of stroke and bleeding.
• Existing LAA closure devices face limitations regarding sheath size and device maneuverability.

Purpose of the Study:

• To introduce and detail the novel LAmbre LAA occluder.
• To describe the unique features and procedural application of the LAmbre device.

Main Methods:

• The LAmbre device is a self-expanding occluder made of nitinol mesh and polyester membranes.
• It features an umbrella and cover connected by a central waist.
• The device is delivered via an 8-10 French sheath and allows full recapture and repositioning.

Main Results:

• The LAmbre device presents a new option for LAA closure.
• Its design facilitates easier delivery and enhanced maneuverability compared to existing devices.
• Detailed procedural steps for its application are discussed.

Conclusions:

• The LAmbre device offers potential advantages in percutaneous LAA closure.
• Its design addresses limitations of current devices, particularly sheath size and repositioning.
• Further clinical evaluation will determine its efficacy and safety in managing stroke risk in AF patients.
