Cierre percutáneo de orejuela izquierda con dispositivo LAmbre / Percutaneous closure of the left atrial appendage using the LAmbre device

ABSTRACT

Abstract Atrial fibrillation (AF) is an increasing health care problem associated with thromboembolic risk about 5% per year, with high mortality and morbidity when associated to stroke. Oral anticoagulants (OAC) are the treatment of choice for preventing ischemic stroke in patients with nonvalvular atrial fibrillation (NVAF). However, these drugs are associated with an increased risk of serious complications such an intracranial hemorrhage (ICH). In this context percutaneous closure of the left atrial appendage (LAA) is an effective therapeutic alternative to OACs, with an increasing success rate. Novel devices might allow or facilitate the procedure in some anatomically and technically complicated cases. Two patients with a complex morphology of the LAA, in which the LAmbre (Lifetech Scientific [Shenzhen] Co. Ltd.) device was implanted with good technical and clinical results are presented.
