Doppler echocardiography has greatly enhanced the information provided by two-dimensional echocardiography. By providing information concerning pressure gradients, intracardiac pressures, volumetric flow, and diastolic filling of the heart, most hemodynamic information that in the past could be obtained only from cardiac catheterization can now be provided accurately and noninvasively by Doppler echocardiography. Future developments in instrument technology and understanding of the various Doppler velocity curves should further aid in the ability to obtain a complete, noninvasive hemodynamic assessment of the patient with cardiac disease.
多普勒超声心动图极大地增强了二维超声心动图所提供的信息。通过提供有关压力梯度、心腔内压力、容积流量和心脏舒张期充盈的信息，过去只能通过心导管检查获得的大多数血流动力学信息，现在可以通过多普勒超声心动图准确且无创地提供。仪器技术的未来发展以及对各种多普勒速度曲线的理解，应进一步有助于对心脏病患者进行完整的无创血流动力学评估。
