The commonly used left atrial appendage (LAA) occlusion (LAAO) devices, Watchman (Boston Scientific, Marlborough, MA, USA) and Amulet (Abbott, Plymouth, Minnesota, USA), both rely on oversizing for stabilization. Therefore, occluding large LAA (ostium >=31mm for Watchman or landing zone >=31mm for Amulet) are not possible. LAmbre (Lifetech Scientific Co., Shenzhen, China) device has an additional stabilization mechanism by catching the LAA trabeculations using its 8 claws1. This potentially allows LAmbre in occluding large LAA with ostium up to 40mm, i.e. size of its largest cover.  The study Aims:ed to evaluate procedural and short-term outcomes of LAmbre device in occluding large LAA.
