Coronary Angiography in Isolated Hearts and Its Forensic Application / 法医学杂志

ABSTRACT

ObjectiveTo check the isolated heart by coronary angiography to discover the location, na-ture and degree of the coronary artery lesions more accurately and increase the comprehensive evaluation ability of cardiovascular disease.MethodsTen fresh isolated hearts with different causes of death were extracted and injected with barium sulphate as contrast substance by ring injector, then developed under Xper FD20 angiography equipment. The obtained pictures and image data were handled by three-dimen-sional angiography images with the software attached to the angiography equipment. The coronary artery tissues were HE stained and observed by microscope. The HE staining results were compared with the angiographic results.ResultsThe imaging data obtained from the 10 cases for examination showed 8 cases without coronary artery stenosis and 2 cases with Ⅲ, Ⅳcoronary artery stenosis, which were consistent with HE staining results of coronary artery organization and the both results were confirmed. ConclusionIsolated coronary angiography has an unique advantage for accurate grading of classification of coronary artery stenosis, examination of vascular malformation and tiny lesions, which can provide reference for the localization of small lesions and basis during the autopsy for identification conclusion.
