摘要

左房在维持正常的收缩与舒张功能

以及预测心血管疾病患者预后等方面均具有重要的价值。传统超声心动图对左房功能的评估基于左房长度、面积及容积的测量

但在心脏疾病早期对左房功能评估具有一定的局限性。近年来

随着超声技术的不断发展

三维斑点追踪成像可以在左房解剖结构变化之前发现左房时相功能的变化

在心脏疾病的早期诊断及评估预后方面有着重要价值。本文就三维斑点追踪成像在评估左房功能方面的价值进行综述。

Abstract

Left atrium plays a critical role in maintaining the normal left ventricular systolic and diastolic function and predicting the prognosis of patients with 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（3 D-STI）

it allows discovering the changes 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 3 D-STI in evaluating left atrial function is reviewed in this article.
