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

Non-valvular atrial fibrillation (AF) is the commonest cardiac arrhythmia which causes ischemic stroke. Percutaneous left atrial appendage (LAA) closure is increasingly performed in AF patients with high stroke and bleeding risks. WATCHMAN and Amplatzer Cardiac Plug are the two mostly implanted devices worldwide with good clinical results. However, the need for relatively large delivery sheaths (9-14 French) and limited recapture and repositioning capabilities remains problematic for both devices. LAmbre (TM) is a new; self-expanding LAA occluder constructed from a nitinol mesh and polyester membranes. It consists of an umbrella and a cover connected by a short central waist. The device is delivered by an 8-10 French sheath and has full recapture and repositioning capabilities. This report discussed in detail the novel features andprocedural steps for LAmbre (TM) device.
