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 success. Even though the effect of a learning curve has not been directly tested, the volume of LAAO procedures per center has recently been inversely associated with major adverse events. A need for skills training and preprocedural technical expertise development has emerged, particularly in structural heart interventions where case volume is still low. Read More.
