The left atrial appendage (LAA) is one of the major sites of cardiac thrombus formation. Recently, a large retrospective study found a relationship between specific types of LAA morphology and earlier thromboembolic events by means of computed tomography (CT) and cardiac magnetic resonance (CMR). In particular, minor events were seen in chicken wing LAA morphology. CT and CMR are unfavorable in terms of costs and availability, and CT confers a significant radiation exposure. In contrast, 3-dimensional transesophageal echocardiography (3D TEE) is a novel imaging tool that captures detailed anatomic information and can easily and cost effectively be integrated into clinical routine (Figures 1 and 2)⇓⇓. Although earlier studies showed high concordance for LAA morphology data derived from 3D TEE and porcine LAA specimens, the role of 3D TEE in the clinical setting had not been evaluated.
The authors have reported that they have no relationships relevant to the contents of this paper to disclose.
