We have read with great interest the paper entitled ‘First results of the Brazilian Registry of Percutaneous Left Atrial Appendage Closure’ by Guérios et al. is a very important study. We have some suggestions about this trial. Firstly, two-dimensional transeosophageal echocardiography (2D-TEE) can evaluate the morphology of left atrial appendage in multiple views. But real-time three-dimensional transeosophageal echocardiography (3D-TEE) provides more detailed images of the left atrial appendage (LAA) anatomy than 2D-TEE. A competent physician can accurately evaluate the LAA […]

Abstract Background: Left atrial appendage closure (LAAC) is an effective alternative to oral anticoagulation (OA) for the prevention of stroke in patients with non-valvular atrial fibrillation (NVAF). Objective: To present the immediate results and late outcomes of patients submitted to LAAC and included in the Brazilian Registry of Percutaneous Left Atrial Appendage Closure. Methods: 91 patients with NVAF, high stroke risk (CHA2DS2VASc score = 4.5 ± 1.5) and restrictions to OAC (HAS-BLED score = 3.6 ± 1.0) underwent 92 LAAC […]
