This review aims to highlight the general and specific strengths and limitations of intraoperative 3D echocardiography. This article explains the value of real-time three-dimensional transesophageal echocardiography (RT 3D TEE) during cardiac surgery and cardiac interventions.
Recently published recommendations and guidelines include the use of RT 3D TEE. RT 3 D TEE provides additional value particularly for guidance during cardiac interventions (i.e., transcatheter mitral valve repair, left atrial appendix and atrial septal defect closures), assessment of the mitral valve in surgical repair, measurement of left ventricular outflow tract area for transcatheter valvular replacements, and estimating right and left ventricular volumes and function. The exact localization of paravalvular leakage is another strength of RT 3D TEE. The major limitation is the reduced temporal resolution compared to 2D TEE.
Three-dimensional echocardiography is a powerful tool that improves communication and accurate measurements of cardiac structures.
本综述旨在强调术中三维超声心动图的一般及特定优势与局限性。本文阐述了实时三维经食管超声心动图（RT 3D TEE）在心脏手术及心脏介入治疗中的价值。
近期发布的推荐意见和指南包括使用RT 3D TEE。RT 3D TEE尤其在心脏介入治疗（即经导管二尖瓣修复、左心耳及房间隔缺损封堵）期间的引导、手术修复中二尖瓣的评估、经导管瓣膜置换时左心室流出道面积的测量以及左右心室容积和功能的估计方面具有额外价值。瓣周漏的精确定位是RT 3D TEE的另一优势。主要局限性是与二维TEE相比时间分辨率降低。
三维超声心动图是一种强大的工具，可改善心脏结构的沟通及精确测量。
