Percutaneous left atrial appendage (LAA) occlusion (LAAO) is an alternative to oral anticoagulation for those patients with atrial fibrillation and a contraindication to or high risk for anticoagulation1. LAAO procedures are typically performed with a 3D imaging technique (transoesophageal echocardiography [TOE] or computed tomography [CT]). For intraprocedural guidance, 3D-TOE is generally used, requiring general anaesthesia in most centres. Technological improvements such as the micro-TOE probe (10T-D; GE Healthcare)2, allow LAAO guidance using only minimal sedation and resulting in same-day patient hospital discharge. However, micro-TOE also has limitations (monoplane imaging, bad visualisation of the far field, need for specialised trainingâ€&...
