Until recently the left atrium had been subordinate to the left ventricle, but cardiologists now recognize that left atrial (LA) function is indispensable to normal circulatory performance. Transthoracic two-dimensional (2D) and Doppler echocardiography can elucidate parameters of LA function non-invasively. Yet, with the advent of 2D speckle-tracking echocardiography, we are able to detect early LA dysfunction even before structural changes occur. This is pivotal in some common disease states, such as atrial fibrillation, hypertension, and heart failure, in which LA deformation parameters can influence clinical management. However, a unique standardized technique to investigate LA deformation needs to be validated.
直到最近，左心房一直从属于左心室，但心脏病专家现在认识到，左心房（LA）功能对于正常循环功能是不可或缺的。经胸二维（2D）和多普勒超声心动图可以无创地阐明 LA 功能的参数。然而，随着 2D 斑点追踪超声心动图的出现，我们甚至可以在结构发生变化之前检测到 LA 功能障碍。这在一些常见疾病状态中至关重要，如心房颤动、高血压和心力衰竭，其中 LA 变形参数可以影响临床管理。然而，需要验证一种独特的标准化技术来研究 LA 变形。
