Noninvasive Doppler-echocardiographic estimates of cardiac output correlate well with invasive measures of cardiac output, making Doppler echocardiography useful in clinical practice. The ability of Doppler echocardiography to measure flow at multiple sites within the heart makes calculation of intracardiac shunt flow ratios and regurgitant flow volume possible. Measurement of flows at stenotic and nonstenotic sites provides the potential for determining the area of a stenotic valve without cardiac catheterization. Although considerable work must be done before all of these methods can be applied routinely, Doppler echocardiography is clearly emerging as a powerful quantitative tool that greatly enhances the strength of noninvasive evaluation in cardiac diagnosis and management.
无创多普勒超声心动图对心输出量的估计与心输出量的有创测量方法相关性良好，这使得多普勒超声心动图在临床实践中很有用。多普勒超声心动图能够测量心脏内多个部位的血流，从而可以计算心内分流流量比和反流流量。在狭窄和非狭窄部位测量血流，为无需心导管检查就能确定狭窄瓣膜面积提供了可能。尽管在所有这些方法能够常规应用之前还需要做大量工作，但多普勒超声心动图显然正在成为一种强大的定量工具，极大地增强了心脏诊断和管理中非侵入性评估的力度。
