Despite substantial advances in the imaging techniques and pathophysiological understanding over the last decades, identification of the underlying causes of left ventricular hypertrophy by means of echocardiographic examination remains a challenge in current clinical practice. The longitudinal strain bull's eye plot derived from 2D speckle tracking imaging offers an intuitive visual overview of the global and regional left ventricular myocardial function in a single diagram. The bull's eye mapping is clinically feasible and the plot patterns could provide clues to the etiology of cardiomyopathies. The present review summarizes the longitudinal strain, bull's eye plot features in patients with various cardiomyopathies and concentric left ventricular hypertrophy and the bull's eye plot features might serve as one of the cardiac workup steps on evaluating patients with left ventricular hypertrophy.
尽管在过去几十年中,成像技术和病理生理学认识取得了重大进展,但在当前临床实践中,通过超声心动图检查确定左心室肥厚的潜在原因仍然是一项挑战。从二维斑点追踪成像得出的纵向应变靶心图能在一张图中直观地呈现左心室整体和局部心肌功能的概况。靶心图绘制在临床上是可行的,其图形模式可为心肌病的病因提供线索。本综述总结了各种心肌病和同心性左心室肥厚患者的纵向应变、靶心图特征,这些靶心图特征可能作为评估左心室肥厚患者心脏检查的步骤之一。
