背景资料：通过传统二维超声心动图获得的二尖瓣环（MA）尺寸标准化较差，并且不符合解剖学原则。方法：对17例受试者进行超声心动图和心脏CT检查，并将二尖瓣环前后轴（AP）和连合轴（CC）的正确解剖成像平面与传统方法进行比较。传统的方法是在胸骨旁长轴和心尖四腔切面上获得的。心尖长轴位获得了正确的解剖成像平面。结果：传统方法测量MA与心脏CT相关性较差（AP轴：r=0.13; CC轴：r=0.02）。MA测量的正确解剖成像平面法与心脏CT相关性良好（AP轴：r=0.96; CC轴：r=0.91）（P
Background: Mitral annular (MA) dimensions obtained by traditional two-dimensional echocardiography are poorly standardized and do not adhere to anatomic principles. Correct anatomic imaging planes of the anterior-posterior (AP) and commissure-commissure (CC) axes of the mitral annulus were compared with the traditional method and correlated with cardiac computed tomography (CT).Methods: Seventeen subjects underwent traditional and correct anatomic imaging planes echocardiography and cardiac CT. The traditional method was obtained in the parasternal long-axis and apical 4-chamber views. Correct anatomic imaging planes were obtained in the apical long-axis view. The traditional and correct anatomic images planes methods were correlated with cardiac CT.Results: The traditional method of MA measurement correlated poorly with cardiac CT (AP axis: r=0.13; CC axis: r=0.02). The correct anatomic imaging planes method of MA measurement correlated very well with cardiac CT (AP axis: r=0.96; CC axis: r=0.91) (P
