The commonly used left atrial appendage (LAA) occlusion (LAAO) devices, the WATCHMAN™ (Boston Scientific, Marlborough, MA, USA) and the AMPLATZER™ Amulet™ (Abbott Vascular, Santa Clara, CA, USA), both rely on oversizing for stabilisation. Therefore, occluding large LAA (ostium ≥31 mm for the WATCHMAN or landing zone ≥31 mm for the AMPLATZER Amulet) is not possible. The LAmbre™ device (Lifetech Scientific [Shenzhen] Co., Ltd. Shenzhen, China) has an additional stabilisation mechanism which catches the LAA trabeculations using its eight claws1. This potentially allows LAmbre to occlude a large LAA with an ostium up to 40 mm, ...
