Occluding morphologically complicated left atrial appendage using the small-umbrella LAmbre device.

ABSTRACT:

Background

Percutaneous left atrial appendage (LAA) occlusion is effective for stroke prevention in patients with atrial fibrillation. LAA can have a complex anatomy, such as multiple lobes or a large orifice, which may render it unsuitable for occlusion using regular devices. We aimed to investigate the feasibility, safety, and short-term efficacy of the small-umbrella LAmbre device for morphologically complicated LAA.

Methods

We retrospectively enrolled 129 consecutive patients who underwent LAA occlusion using the LAmbre device; the small-umbrella LAmbre device was used in 30 of these patients. We analyzed patients' characteristics, procedural details, and outcomes.

Results

Twenty-two patients (73.3%) had multilobed (≥ 2) LAA. The umbrella of the occluder was ancho
