The correlation between normal cardiac chamber linear dimensions measured during retrospective coronary computed tomographic angiography as compared to transthoracic echocardiography using the American Society of Echocardiography guidelines is not well established.
We performed a review from January 2005 to July 2011 to identify subjects with retrospective electrocardiogram-gated coronary computed tomographic angiography scans for chest pain and transthoracic echocardiography with normal cardiac structures performed within 90 days. Dimensions were manually calculated in both imaging modalities in accordance with the American Society of Echocardiography published guidelines. Left ventricular ejection fraction was calculated on echocardiography manually using the Simpson's formula and by coronary computed tomographic angiography using the end-systolic and end-diastolic volumes.
We reviewed 532 studies, rejected 412 and had 120 cases for review with a median time between studies of 7 days (interquartile range (IQR25,75) = 0-22 days) with no correlation between the measurements made by coronary computed tomographic angiography and transthoracic echocardiography using Bland-Altman analysis. We generated coronary computed tomographic angiography cardiac dimension reference ranges for both genders for our population.
Our findings represent a step towards generating cardiac chamber dimensions' reference ranges for coronary computed tomographic angiography as compared to transthoracic echocardiography in patients with normal cardiac morphology and function using the American Society of Echocardiography guideline measurements that are commonly used by cardiologists.
与经胸超声心动图相比，在回顾性冠状动脉计算机断层血管造影期间测量的正常心腔线性尺寸之间的相关性，使用美国超声心动图学会指南尚未明确确立。
我们对2005年1月至2011年7月期间进行回顾性心电图门控冠状动脉计算机断层血管造影扫描以评估胸痛的受试者以及在90天内进行心脏结构正常的经胸超声心动图检查的受试者进行了回顾。在两种成像模式中均根据美国超声心动图学会发布的指南手动计算尺寸。在超声心动图上使用辛普森公式手动计算左心室射血分数，并通过冠状动脉计算机断层血管造影使用收缩末期和舒张末期容积计算。
我们回顾了532项研究，排除了412项，有120例进行回顾，研究之间的中位时间为7天（四分位间距（IQR25,75）= 0 - 22天），使用布兰德-奥特曼分析，冠状动脉计算机断层血管造影和经胸超声心动图测量之间无相关性。我们为我们的人群生成了两性的冠状动脉计算机断层血管造影心脏尺寸参考范围。
我们的研究结果朝着为心脏形态和功能正常的患者生成冠状动脉计算机断层血管造影与经胸超声心动图相比的心腔尺寸参考范围迈出了一步，该参考范围使用了心脏病专家常用的美国超声心动图学会指南测量方法。
