The 2D echocardiographic examination of the heart provides insight into structure and function, providing a precise anatomical display of the cardiovascular anatomy with high temporal resolution. Prior to advances in 2D imaging, Doppler echocardiography had been the mainstay of cardiovascular noninvasive assessment. Doppler echocardiography, remains an integral part of the cardiovascular echocardiographic examination, providing a precise hemodyanamic evaluation of the heart. Both systolic and diastolic function can be quantitated by blood pool and tissue Doppler. Pressure gradients, intracardiac pressures, valve areas, regurgitant volume, and shunt volume can be noninvasively determined reliably. Based on Doppler hemodynamics as well as on 2D echocardiography, most of hemodynamic conditions can be managed surgically as well as medically without invasive hemodynamic measurements. We present a review of these current applications of Doppler echocardiography.
二维超声心动图检查可深入了解心脏的结构和功能，以高时间分辨率提供心血管解剖结构的精确解剖学显示。在二维成像技术进步之前，多普勒超声心动图一直是心血管无创评估的主要手段。多普勒超声心动图仍然是心血管超声心动图检查的一个组成部分，可对心脏的血液动力学进行精确评估。可以通过血池和组织多普勒定量评估收缩和舒张功能。可以可靠地无创确定压力梯度、心内压、瓣膜面积、反流容积和分流容积。基于多普勒血液动力学以及二维超声心动图，大多数血液动力学情况都可以通过手术和非侵入性血液动力学测量进行治疗。我们对这些当前的多普勒超声心动图应用进行了综述。
