| 摘要: |
| 相对于左心室而言,左心房是一个容易被忽视的腔室。然而，左心房功能在预测心血管患者的预后方面具有重要的价值。传统超声心动图对左心房功能的评估基于左心房长度 、面积以及容积的测量。在疾病早期，上述传统超声指标往往未见明显异常，所以在早期评估左心房功能方面有一定的局限性。近年来、随着超声技术的不断发展，三维斑点追踪技术(3-dimensional speckle tracking imaging, 3D-STI)可以在左心房解剖结构变化之前，发现左心房时相功能的变化，在心脏病疾病的早期诊断及预后评估方面具有显著的价值,本文就3D-STI在评估左心房功能方面做一简要综述。 |

| Abstract: |
| Left atrium is often overlooked compared with left ventricular. However, the left atrial function plays a critical role in the prognosis of patient of cardiovascular events. conventional echocardiography detect left atrium dysfunction through mono-dimensional left atrial diameter quantification、bi-dimensional areas and volume estimation. The conventional parameters are often normal in early stage of the diseases, so there are some limits in evaluating the left atrial function early. Recently, with the progress of the echocardiography, especially three-dimensional speckle tracking imaging，it allows discover the change of left atrial function before anatomical alteration occurs and has great values in the diagnosis of the cardiovascular disease early and assessing the prognosis of diseases，The role of 3D-STI in evaluating left atrial function were reviewed in this article |
| Key words: left atrial function, three-dimensional speckle tracking imaging,strain,strain rate |
