Abstract

Transesophageal echocardiography (TEE) is an established cardiovascular diagnostic technique. Left atrial (LA) size, as measured by transthoracic echocardiography (TTE), is associated with cardiovascular disease and is a risk factor for atrial fibrillation, stroke, death, and the success of cardioversion. Assessment of LA size has not been as well validated on TEE as on TTE. We determined LA size measurements in four standard views in 122 patients undergoing TEE and TTE at the same setting. In this study, we found that measurement of LA dimensions by TEE suffers from significant limitations in all views except the basal long-axis view (mid-esophageal level) with transducer plane at 120-150 degrees. This view had the best correlation with transthoracic LA measurements: r = 0.79 for TEE long axis (CI 0.71-0.85), P <.0001.

摘要

经食管超声心动图（TEE）是一种成熟的心血管诊断技术。经胸超声心动图（TTE）测量的左心房（LA）大小与心血管疾病相关，并且是心房颤动、中风、死亡以及心脏复律成功与否的危险因素。LA大小的评估在TEE上不如在TTE上那样得到充分验证。我们在同一环境下对122例接受TEE和TTE检查的患者，在四个标准视图中测定了LA大小。在本研究中，我们发现，除了在换能器平面为120 - 150度的基底长轴视图（食管中段水平）外，TEE测量LA尺寸在所有视图中都存在显著局限性。该视图与经胸LA测量的相关性最佳：TEE长轴的r = 0.79（CI 0.71 - 0.85），P <.0001。
