The following review will focus on the current advances in both echocardiography and cardiovascular MRI (CMRI) in the assessment of cardiac function.
The assessment of cardiac function in pediatric patients and in congenital heart disease (CHD) patients has dramatically improved over the last several years. The advancement of transthoracic echocardiography with tissue Doppler imaging, speckle tracking, and three-dimensional echocardiography has enabled strain assessment and the ability to estimate ventricular volumes in these complex patients. In the last few decades, CMRI has become an imaging modality that is now part of the standard tools used for cardiac assessment. With superb two-dimensional and three-dimensional resolution, CMRI allows clear delineation of cardiac and extracardiac structures as well as accurate and reproducible assessment of ventricular volume and function. The most recent and robust contributions of CMRI are its ability to provide characterization of the myocardium and the development of new measurements of global and regional myocardial mechanics and function.
Recent advances in echocardiography and CMRI allow a better understanding of myocardial mechanics and composition as well as accurate assessment of ventricular volume and global and regional function in the complex and unique anatomy often found in CHD patients.
本综述将重点介绍超声心动图和心血管磁共振（CMRI）在评估心功能方面的最新进展。
在过去的几年中，儿科患者和先天性心脏病（CHD）患者的心功能评估有了显著的提高。经胸超声心动图技术的发展，包括组织多普勒成像、斑点追踪和三维超声心动图，使应变评估和心室容量估计成为可能，这些复杂患者受益于此。在过去的几十年中，CMRI 已经成为一种成像方式，现在是心脏评估标准工具的一部分。CMRI 具有出色的二维和三维分辨率，能够清晰地描绘心脏和心脏外结构，以及准确和可重复的心室容量和功能评估。CMRI 的最新和最有力的贡献是其能够对心肌进行特征描述，并开发出测量整体和局部心肌力学和功能的新方法。
超声心动图和 CMRI 的最新进展使人们更好地了解心肌力学和组成，以及在 CHD 患者中常见的复杂而独特的解剖结构中，准确评估心室容量和整体及局部功能。
