美国超声心动图学会（ASE）推荐使用舒张期面积长度和截短椭圆体方法通过二维（2D）超声心动图估计左心室（LV）质量。本回顾性研究的主要目的是（1）评估ASE推荐的2D和M模式超声心动图导出的LV质量测量值之间的相关性，（2）比较两种ASE推荐的2D超声心动图方法，（3）比较超声心动图导出的LV质量与解剖LV质量。该研究包括34名随后进行尸检的患者在死亡后30天内获得的2D超声心动图和56名正常受试者的2D超声心动图。用于测量M模式回波导出的LV质量的公式为LV质量= 0.8（ASE立方体LV质量）+ 0.6 gm。对于2D回波导出的LV质量，使用ASE推荐的收缩期和舒张期面积长度和截短椭圆体方法，将乳头肌纳入和不纳入心肌壳。M型超声心动图得出的左室质量与2D方法得出的左室质量相当，对于正常形状的心室使用该技术是合理的。当乳头肌被包括在心肌壳中时，舒张2D方法高估了尸检LV质量。舒张期面积长度和截短椭圆体方法与尸检LV质量相当。当排除乳头肌时，收缩面积长度法显示与尸检左室质量最一致。
The American Society of Echocardiography (ASE) has recommended diastolic area length and truncated ellipsoid methods for estimating left ventricular (LV) mass by two-dimensional (2D) echocardiography. The major goals of this retrospective study were to (1) assess the correlation between ASE-recommended 2D and M-mode echo-derived measurements of LV mass, (2) compare the two ASE-recommended 2D echocardiography methods, and (3) compare the echo-derived LV mass with anatomic LV mass. The study included 2D echocardiograms obtained within 30 days of death from 34 patients who subsequently underwent autopsy and 2D echocardiograms of 56 normal subjects. The formula used for measurement of M-mode echo-derived LV mass was LV mass = 0.8 (ASE-cube LV mass) + 0.6 gm. For 2D echo-derived LV mass, the ASE-recommended area length and truncated ellipsoid methods in systole and diastole were used, with and without incorporating the papillary muscles into the myocardial shell. LV mass derived by M-mode echocardiography was comparable to that derived by 2D methods, and it is reasonable to use this technique for normally shaped ventricles. When the papillary muscles were included into the myocardial shell, diastolic 2D methods overestimated autopsy LV mass. Both diastolic area length and truncated ellipsoid methods were comparable to autopsy LV mass. When the papillary muscles were excluded, the systolic area length method showed the best agreement with autopsy LV mass.
