The purpose of this study was to assess the contribution of digital subtraction angiography (DSA) to the quantification of aortic valve regurgitation in 21 patients undergoing heart catheterization. The digital image subtraction was used for densitometric evaluation. The regurgitation was derived from the distribution of contrast volumes during diastole in aortic and left ventricular "regions of interest". DSA-measurements were compared with results of conventional cineangiography. Results showed the following correlation between DSA measurements and cineangiographic estimates (grades I-III): regurgitation 1.7-9.8% in grade I (n = 11), 8.9-22.3% in grade II (n = 5), 31.7 and 32.5% in grade II-III (n = 2), 37-42.4% in grade III (n = 3). DSA and digital densitometry seem to be valuable methods for the quantification of regurgitation. Concerning quantitative measurements in left heart catheterization the digital subtraction aortography is superior to conventional cineangiography and will be helpful to characterize patients with aortic regurgitation more completely.
本研究的目的是评估数字减影血管造影（DSA）对21例接受心脏导管检查患者主动脉瓣反流定量的贡献。数字图像减法用于密度测定评估。反流是根据舒张期主动脉和左心室“感兴趣区域”内造影剂体积的分布得出的。将DSA测量结果与传统电影血管造影的结果进行比较。结果显示DSA测量结果与电影血管造影评估结果（I - III级）之间存在以下相关性：I级反流为1.7 - 9.8%（n = 11），II级为8.9 - 22.3%（n = 5），II - III级为31.7%和32.5%（n = 2），III级为37 - 42.4%（n = 3）。DSA和数字密度测定似乎是反流定量的有价值方法。关于左心导管检查中的定量测量，数字减影主动脉造影优于传统电影血管造影，将有助于更全面地对主动脉反流患者进行特征描述。
