Abstract

The rapid development of catheter ablation techniques for atrial arrhythmias has triggered a renewed interest in the anatomy of the right atrium. In particular, some atrial arrhythmias such as focal atrial arrhythmias or atrial flutter have been linked to the anatomic architecture of specific structures such as the crista terminalis or cavotricuspid isthmus. Real-time 3-dimensional transesophageal echocardiography (RT 3D TEE) is a recently developed technique that provides 3D images of unprecedented quality. Because the right atrium is very close to the transducer, this technique may provide high-quality images of those atrial structures involved in ablation procedures. This review describes a step-by-step approach for acquisition and processing of RT 3D TEE images of right atrial structures of relevance to electrophysiologists. For anatomical correlations of RT 3D TEE images, selected images of right atrial structures were matched to anatomical specimens.
