Nowadays, by means of the conventional and Doppler echocardiography it is possible to diagnose with high sensitivity and specificity a defect of the aortic valve. Apart from references to the etiology kind and size of the lesion of the aortic valve, the degree of an obstruction and/or regurgitation as well as degree of hypertrophy and function of the left ventricle are reliably recognizable. Thereby the one- and two-dimensional echocardiography on the one hand and the Doppler methods on the other a different value is ascribed to in the diagnostic statement. By means of Doppler echocardiography the essential functional parameters of a stenosis of the aortic stenosis such as pressure gradient and surface of the opening of the aortic valve are to be determined noninvasively. An insufficiency of the aortic valve only by Doppler methods can be determined non-invasively without doubt. Under certain prerequisites the complex echocardiography can be made dispensable the invasive diagnostics in patients with defects of the aortic valve under preoperative aspects--apart from a coronary angiography.
如今，借助传统超声心动图和多普勒超声心动图，能够以高灵敏度和特异性诊断主动脉瓣缺损。除了提及主动脉瓣病变的病因类型和大小外，还能可靠地识别梗阻和/或反流程度以及左心室肥厚程度和功能。因此，在诊断陈述中，一维和二维超声心动图与多普勒方法具有不同的价值。借助多普勒超声心动图，可以无创地确定主动脉狭窄的关键功能参数，如压力梯度和主动脉瓣开口面积。毫无疑问，仅通过多普勒方法就能无创地确定主动脉瓣关闭不全。在某些前提下，除了冠状动脉造影外，在术前方面，复杂的超声心动图可使主动脉瓣缺损患者的侵入性诊断变得不必要。
