Abstract

In patients with atrial fibrillation (AF), most thrombus forms in the left atrial appendage (LAA).1 However, the relation of LAA morphology with LAA thrombus is unknown. In this study we prospectively enrolled 60 patients who had non valvular atrial fibrillation. Transoesophageal echocardiography (TEE) was performed to assess LAA thrombus. LAA structure was assessed by 3-dimensional TEE. LAA volume and number of lobes were measured on reconstructed 3-dimensional images. Clinical characteristics and echocardiographic measures were compared to determine variables predicting LAA thrombus.
