Objectives:
To check the isolated heart by coronary angiography to discover the location, nature and degree of the coronary artery lesions more accurately and increase the comprehensive evaluation ability of cardiovascular disease.
Methods:
Ten 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-dimensional 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.
Results:
The imaging data obtained from the 10 cases for examination showed 8 cases without coronary artery stenosis and 2 cases with Ⅲ, Ⅳ coronary artery stenosis, which were consistent with HE staining results of coronary artery organization and the both results were confirmed.
Conclusions:
Isolated 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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
