左心房的体积和功能被认为可反映左心室舒张功能,可预测心血管疾病的结局,早期准确评价左心房功能对临床诊疗、评价治疗效果及预后具有重要的价值.三维斑点追踪成像技术因其不受心脏运动的影响,无角度依赖性,能准确地对整体和节段心肌形变进行评价,近年来被应用于评估各种疾病的左房大小及功能.以下就应用三维班点追踪成像技术评价左心房功能的进展做一综述.“,”Left atrial( LA) volume and function is considered to reflect left ventricular diastolic function and predict adverse cardio -vascular outcomes .It is important to evaluate LA function early and accurately to guide the clinical diagnosis and treatment , therapeutic effects and prognosis .Three-dimensional speckle tracking echocardiography (3D-STE) has major advantage in that no-governed by the move-ments of the heart,angle-independent and accuracy in the evaluation of global and regional myocardial deformation .3D-STE has recently ap-plied to evaluate LA size and function in various diseases .This article reviews the assessment of LA analysis with 3D-STE.
