To review the essential elements of the transesophageal echocardiographic examination of the aortic valve, with emphasis on the technique for performing a two-dimensional examination, the quantification of aortic stenosis and regurgitation, and the effect of this modality on cardiac surgical decision making.
Literature review.
Transesophageal echocardiographic examination of the aortic valve can provide detailed information on aortic valve structure and function, provided proper technique is utilized. This review presents the current recommendations from the American Society of Echocardiography for the performance of a two-dimensional examination of the aortic valve and for the quantification of aortic stenosis or aortic regurgitation by application of Doppler techniques. To demonstrate the applicability of transesophageal echocardiography in clinical practice, the effect of transesophageal echocardiography on the cardiac surgical management of patients with aortic valvular disease is described.
回顾经食管超声心动图检查主动脉瓣的基本要素，重点关注二维检查技术、主动脉瓣狭窄和反流的量化，以及该检查方式对心脏外科手术决策的影响。
文献综述。
如果采用恰当的技术，经食管超声心动图检查主动脉瓣可提供有关主动脉瓣结构和功能的详细信息。本综述介绍了美国超声心动图学会目前关于主动脉瓣二维检查以及应用多普勒技术量化主动脉瓣狭窄或反流的建议。为证明经食管超声心动图在临床实践中的适用性，还描述了经食管超声心动图对主动脉瓣疾病患者心脏外科治疗的影响。
