With the deepening of research on cardiovascular diseases, left atrial remodeling (LAR) and left atrial reverse remodeling (LARR) have become important research hotspots, closely related to various adverse cardiovascular pathological changes. As a non-invasive and convenient diagnostic tool, echocardiography plays a crucial role in the diagnosis, treatment monitoring, and prognosis evaluation of LAR and LARR. This article reviews the research progress of echocardiography in evaluating LAR and LARR, involving transthoracic echocardiography, tissue Doppler imaging, two-dimensional speckle tracking echocardiography, and three-dimensional speckle tracking echocardiography, and explores their advantages and limitations in clinical practice.
