背景：左心房（LA）大小在各种心脏疾病中具有重要的预后意义。二维（2D）超声心动图（2DE）得出的直径、面积或体积通常用于测量左心房大小，但涉及许多假设。本研究比较了这些二维超声心动图参数与三维超声心动图左心房容积（3DV）的准确性。方法：在118例扩张型心肌病、肥厚型心肌病或无器质性心脏病的患者中，将二维超声心动图测量的左心房直径、面积和容积与3DV进行相关性分析。直径（前-后、上-下和内外侧）和2DE面积测量与3DV具有统计学显著但适度的相关性，并且与3DV相比表现出很大程度的散射。2DE导出的容积与3DV有很好的相关性，但一致低估了LA volume.Conclusion：2DE LA容积与3DV的相关性优于其他参数，但往往导致低估。因此，使用左心房尺寸的一维和二维测量值时应谨慎。
Background: Left atrial (LA) size has prognostic importance in a variety of cardiac conditions. Diameters, area, or volume derived from 2-dimensional (2D) echocardiography (2DE) are commonly used to measure LA size, but involve numerous assumptions. This study examined the accuracy of these 2DE parameters compared to 3-dimensional echocardiographic LA volume (3DV).Methods: LA diameters, area, and volume measured from 2DE were correlated with 3DV in 118 patients with dilated cardiomyopathy, hypertrophic cardiomyopathy, or without structural heart disease.Results: Diameter (anterior-posterior, superior-inferior, and medial-lateral) and 2DE area measurements had statistically significant, but modest, correlations with 3DV, and exhibited a large degree of scatter in comparison with 3DV. The 2DE-derived volume had an excellent correlation with 3DV, but consistently underestimated LA volume.Conclusion: The 2DE LA volume correlates better than other parameters with 3DV, but often results in underestimation. Thus, caution should be exercised when using unidimensional and 2D measurements of LA size.
