超声心动图是诊断和评价主动脉瓣狭窄的关键工具。由于临床决策是基于超声心动图对其严重程度的评估，因此必须采用标准来保持超声心动图实验室的准确性和一致性。欧洲超声心动图协会和美国超声心动图协会于2009年发表了关于瓣膜狭窄超声心动图评估的详细建议。与此同时，已经发表了许多关于主动脉瓣狭窄的新研究，特别是对低梯度主动脉瓣狭窄这一困难亚组的新见解，因此有必要更新建议。该文件特别关注左心室流出道评估的优化、低流量、低梯度主动脉瓣狭窄（保留射血分数）、通过梯度、流量和射血分数对主动脉瓣狭窄进行的新分类，以及用于临床实践中主动脉瓣狭窄评估的综合和逐步方法的分级算法。
Echocardiography is the key tool for the diagnosis and evaluation of aortic stenosis. Because clinical decision-making is based on the echocardiographic assessment of its severity, it is essential that standards are adopted to maintain accuracy and consistency across echocardiographic laboratories. Detailed recommendations for the echocardiographic assessment of valve stenosis were published by the European Association of Echocardiography and the American Society of Echocardiography in 2009. In the meantime, numerous new studies on aortic stenosis have been published with particular new insights into the difficult subgroup of low gradient aortic stenosis making an update of recommendations necessary. The document focuses in particular on the optimization of left ventricular outflow tract assessment, low flow, low gradient aortic stenosis with preserved ejection fraction, a new classification of aortic stenosis by gradient, flow and ejection fraction, and a grading algorithm for an integrated and stepwise approach of aortic stenosis assessment in clinical practice.
