Research progresses of echocardiography in evaluation on volume and function of left atrium / 中国医学影像技术

ABSTRACT

Many diseases can affect the structure and function of left atrium. Echocardiography can estimate left atrial volume and function noninvasively, providing quantitative indexes for diagnosis, treatment and prognosis of some diseases. The ellipsoid model or Simpson's rule based on 2D echocardiography can measure the left atrial volume in different functional phases and evaluate the corresponding left atrial function. New techniques, such as speckle tracking echocardiography, real-time three-dimensional echocardiography and velocity vector imaging, can better reflect the function of left atrium. The research progresses of echocardiography in evaluation on left atrial volume and function were reviewed in this article.
