Isotopic angiocardiography was performed in 60 patients with proven congenital left-to-right shunt. A 99mTc labeled bolus was injected in a peripheral vein, and the first passage in the heart cavities was studied. Time-activity curves of the cardiac chambers were analysed, using a scintillation camera and a data processing system. In our study, we were able to confirm the presence of the shunt in 77% of the cases in which the radioactive bolus arrived well grouped in the vena cava. Quantitative results however remain imprecise. Isotopic angiocardiography indications are compared to radiologic angiocardiography and to right heart catheterism indications. Use of this non invasive technique could render more aggressive examinations unnecessary.
对60例已证实存在先天性左向右分流的患者进行了同位素心血管造影。将99mTc标记的团注剂注入外周静脉，研究其在心脏各腔室的首次通过情况。使用闪烁照相机和数据处理系统分析心腔的时间-活性曲线。在我们的研究中，当放射性团注剂在腔静脉中聚集良好时，我们能够在77%的病例中证实分流的存在。然而，定量结果仍然不准确。将同位素心血管造影的适应证与放射学心血管造影和右心导管检查的适应证进行了比较。使用这种非侵入性技术可能无需进行更具侵入性的检查。
