三维（3D）超声心动图的最新技术进展，使用并行处理扫描锥体容积，允许使用经胸和经食管超声心动图描述瓣膜解剖结构的上级能力。尽管3D超声心动图在临床应用方面仍处于发展和适应的早期阶段，但它已成为评估心脏瓣膜病的重要临床工具。三维超声心动图通过呈现瓣膜结构的“正面”视图提供了瓣膜结构的独特视角，允许更好地理解病理学的地形方面，并精确定义心内结构的空间关系。三维超声心动图提供了二维超声心动图无法描述的可用指标，并且已被证明在各种瓣膜疾病情况下上级二维超声心动图。从3D超声心动图获得的信息尤其对指导二尖瓣（MV）疾病评价的临床决策产生了影响。退行性二尖瓣疾病的早期手术决定基于修复的适用性，修复的适用性通常基于超声心动图。3D超声心动图对二尖瓣解剖结构的上级理解在这种情况下非常有价值。本综述将描述三维超声心动图在评估心脏瓣膜疾病（包括二尖瓣、主动脉瓣、三尖瓣和人工瓣膜异常）中的当代应用。本文阐述了如何三维超声心动图可以补充目前的超声心动图技术在心脏瓣膜病的管理。
Recent technologic advances in 3-dimensional (3D) echocardiography, using parallel processing to scan a pyramidal volume, have allowed for a superior ability to describe valvular anatomy using both transthoracic and transesophageal echocardiography. Although still in evolution and at an early phase of adaptation with respect to its clinical application, 3D echocardiography has emerged as an important clinical tool in the assessment of valvular heart disease. Three-dimensional echocardiography provides unique perspectives of valvular structures by presenting “en face” views of valvular structures, allowing for a better understanding of the topographical aspects of pathology, and a refined definition of the spatial relationships of intracardiac structures. Three-dimensional echocardiography makes available indices not described by 2D echocardiography and has been demonstrated to be superior to 2D echocardiography in a variety of valvular disease scenarios. The information gained from 3D echocardiography has especially made an impact in guiding clinical decisions in the evaluation of mitral valve (MV) disease. The decision of early surgery in degenerative MV disease is based on the suitability of repair, and the suitability of repair is generally based on echocardiography. The superior understanding of MV anatomy afforded by 3D echocardiography has been shown to be quite valuable in this setting. This review will describe the contemporary use of 3D echocardiography in the assessment of valvular heart disease, including MV, aortic, tricuspid, and prosthetic valve abnormalities. This article illustrates how 3D echocardiography can complement current echocardiography techniques in the management of valvular heart disease.
