Deformation imaging allows the direct interrogation of myocardial performance, expanding the ability to evaluate ventricular function in children with congenital heart disease (CHD), including assessment of the subpulmonary and systemic right ventricle, single ventricles, and morphologically abnormal left ventricles. Deformation imaging has provided new insights into the pathophysiology of CHD and diagnostic and prognostic information not readily available using conventional echocardiography. However, at present, deformation imaging is not widely used in clinical pediatric echocardiography. In this review, the authors address the various techniques, their evolving use in CHD, where they have provided important insights in CHD, pitfalls and current limitations to their use, and suggestions for their integration into the routine clinical armamentarium.
应变成像可直接评估心肌功能，从而拓展了评估先天性心脏病（CHD）患儿心室功能的能力，包括评估肺下和体循环右心室、单心室以及形态异常的左心室。应变成像为 CHD 的病理生理学以及常规超声心动图难以提供的诊断和预后信息提供了新的见解。然而，目前，应变成像在儿科临床超声心动图中并未得到广泛应用。在这篇综述中，作者讨论了各种技术，及其在 CHD 中的应用进展，包括应变成像在 CHD 中提供重要见解的方面、应用的局限性和潜在缺陷，以及将其整合到常规临床工具中的建议。
