Echocardiographic assessment plays a major role in the evaluation of aortic stenosis (AS). Because of its proven accuracy, ease of applicability, and safety, it is replacing cardiac catheterization for the assessment of AS in many centers.
In this review, we discuss the basic principles of echocardiographic assessment of AS and clinically challenging scenarios including AS with low cardiac output state or other structural heart disease. Dobutamine stress echocardiography is a useful tool for assessing low cardiac output AS. The role of transesophageal echocardiography in the evaluation of AS is also reviewed.
Echocardiographic techniques provide critical information in the assessment of patients with known or suspected AS and guide decision-making regarding the appropriateness of valve replacement.
超声心动图评估在主动脉瓣狭窄（AS）的评估中起着重要作用。由于其已被证实的准确性、易于应用和安全性，在许多中心它正在取代心导管检查用于AS的评估。
在本综述中，我们讨论了AS超声心动图评估的基本原则以及临床上面临挑战的情况，包括低心输出量状态的AS或其他结构性心脏病。多巴酚丁胺负荷超声心动图是评估低心输出量AS的有用工具。还综述了经食管超声心动图在AS评估中的作用。
超声心动图技术在已知或疑似AS患者的评估中提供关键信息，并指导关于瓣膜置换适用性的决策。
