[A new method of comparing intravital and postmortal coronary angiography (author's transl)].

A cardanically suspended plexiglass cylinder, filled with water and containing a specific supporter, enables postmortal hearts to be x-rayed in every possible projection. After filling the coronary vessel system with x-ray contrast medium, intravital angiograms can be repeated postmortally with equitable projection. The diastolic and systolic change of ventricle size in intravital hearts as well as postmortal rigor mortis or relaxation, result in only insignificant differences between postmortem and intravital x-rays of the coronary vessels taken from the same projection. Combined with histological studies, such examinations promise further knowledge about the development of degenerative changes of the coronary vessels. The described apparatus is also suitable for comparative intravital and postmortal x-ray examinations of other organs. With its aid, stereoscopic x-ray pictures can also easily be made.
