During the last decade tissue Doppler and myocardial deformation imaging has been introduced to quantify myocardial function in patients with congenital heart disease. These methods could have potential benefits for patients where the anatomy makes it difficult to quantify ventricular function using M-mode or two-dimensional volumetric techniques. In this overview, the potential benefits as well as limitations of the techniques are discussed. Looking directly into the myocardium renders the techniques geometry-independent, allowing the quantification of right ventricular as well as univentricular systolic function. The limitations include the influence of variable loading conditions as well as different methodological problems.
在过去十年中，组织多普勒和心肌形变成像已被用于量化先天性心脏病患者的心肌功能。对于解剖结构使M型或二维容积技术难以量化心室功能的患者，这些方法可能具有潜在益处。在本综述中，将讨论这些技术的潜在益处和局限性。直接观察心肌使这些技术不受几何形状影响，从而能够量化右心室以及单心室的收缩功能。其局限性包括可变负荷条件的影响以及不同的方法学问题。
