C) TEE views during transseptal puncture (45°) and of the Amulet occluder 31 mm on the BIOMODEX model versus the real patient. D) LAA selective angiography and fluoroscopic views of the Amulet occluder 31 mm on the BIOMODEX model versus the real patient. 

Left atrial appendage occlusion (LAAO) procedural outcomes rely mainly on preprocedural LAA anatomy analysis and operator experience. Preprocedural multimodality imaging, including multislice computed tomography (MSCT), has become the current standard of care and impacts on procedural success1. Even though ...
