A radiographic and hemodynamic investigation has been performed in 53 patients with pure isolated aortic regurgitation, in order to evaluate the most reliable method to detect left ventricular enlargement in this condition. Twelve plain chest film measurements have been compared to the end diastolic volume of the left ventricle calculated by left ventricular angiography. The most sensitive detector of left ventricular enlargement was the plain film total heart volume ( r = 0.754); the cardiothoracic ratio, the cardiac perimeter and the frontal area were less sensitive measurements, but still statistically significant (p less than 0.001). The results of our investigation support the conclusion that plain film total heart volume is the most reliable single measurement for evaluating the left ventricular enlargement in patients with isolated pure aortic incompetence.
对53例单纯性主动脉瓣反流患者进行了影像学和血流动力学研究，以评估在这种情况下检测左心室扩大的最可靠方法。将12项胸部平片测量值与通过左心室造影计算出的左心室舒张末期容积进行了比较。左心室扩大最敏感的检测指标是胸部平片上的全心容积（r = 0.754）；心胸比率、心脏周长和正面面积的敏感性较低，但仍具有统计学意义（p < 0.001）。我们的研究结果支持以下结论：胸部平片全心容积是评估单纯性主动脉瓣关闭不全患者左心室扩大的最可靠单项测量指标。
