二维斑点追踪评价右心功能的进展

Advances in Right Ventricular Function Assessment Using Two-Dimensional Speckle Tracking

摘要: 右心功能的评估在心血管疾病的诊断、治疗和预后判断中具有重要意义。近年来，随着影像学技术的不断发展，尤其是二维斑点追踪(2D Speckle Tracking Imaging, 2D-STE)技术的应用，右心功能的评价方法得到了显著的提升。二维斑点追踪通过分析心脏超声图像中的斑点运动，能够提供更为精确的右心功能评估，尤其是在传统方法难以准确评估的区域，如右心房、右心室的扭转、应变和应变率等方面。本文旨在综述二维斑点追踪技术在右心功能评估中的最新研究进展，探讨其在右心室和右心房功能、右心舒张功能以及与右心功能相关的临床应用中的潜力。文章还将讨论二维斑点追踪技术的局限性和未来发展方向，期望为临床实践提供参考，并促进这一领域的进一步研究。

Abstract: The assessment of right ventricular function plays a significant role in the diagnosis, treatment, and prognosis of cardiovascular diseases. In recent years, with the continuous development of imaging techniques, especially the application of two-dimensional speckle tracking (2D Speckle Tracking Imaging, 2D-STE) technology, the methods for evaluating right ventricular function have been significantly improved. Two-dimensional speckle tracking analyzes the motion of speckles in cardiac ultrasound images, providing a more accurate assessment of right ventricular function, particularly in areas where traditional methods struggle to provide accurate evaluations, such as right atrial and right ventricular torsion, strain, and strain rate. This article aims to review the latest research progress in the application of two-dimensional speckle tracking technology in the assessment of right ventricular function, exploring its potential in the evaluation of right ventricular and right atrial function, right ventricular diastolic function, and its clinical applications related to right ventricular function. The article will also discuss the limitations of two-dimensional speckle tracking technology and its future development directions, with the hope of providing a reference for clinical practice and promoting further research in this field.
