Besides providing spatial anatomic information on heart valves, real-time three-dimensional echocardiography (3DE) combined with color Doppler has the potential to overcome the limitations of flow quantification inherent to conventional 2D color Doppler methods. Recent studies validated the application of color Doppler 3DE (cD-3DE) for the quantification of regurgitation flow based on the vena contracta area (VCA) and the proximal isovelocity surface area (PISA) methods. Particularly the assessment of VCA by cD-3DE led to a change of paradigm by understanding of the VCA as being strongly asymmetric in the majority of patients and etiologies. This review provides a comprehensive description of the different concepts of cD-3DE-based flow quantification in the setting of different valvular heart diseases and their presentation in recent guidelines.
除了提供心脏瓣膜的空间解剖信息外，实时三维超声心动图（3DE）结合彩色多普勒有可能克服传统二维彩色多普勒方法在血流定量方面固有的局限性。最近的研究验证了基于收缩期血流会聚区（VCA）和近端等速表面积（PISA）方法的彩色多普勒三维超声心动图（cD-3DE）在反流血流定量中的应用。特别是通过cD-3DE对VCA的评估导致了一种范式转变，即认识到在大多数患者和病因中VCA存在强烈不对称性。本综述全面描述了基于cD-3DE的血流定量在不同心脏瓣膜疾病中的不同概念及其在最近指南中的呈现。
