[Determination of the types of coronary blood supply by the mass of the blood-supplied zones established on the basis of coronary radiograms].
The dominant coronary arteries and coronary supply types were determined by means of coronary topograms plotted from 305 coronary angiograms, including 30 postmortem ones. Coronary supply types were expressed by the following ratios of numeral values: 5:15, 6:14, 7:13, 8:12, 9:11, 10:10, 11:9, which corresponded to mass scores of the areas supplied through the right (RCA) and the left (LCA) coronary artery. Such determination of coronary supply types in postmortem examinations was verified by separate weighing of the RCA and LCA basins. The data from both methods of investigation showed good correlation (r = 0.977). By separate weighing of the RCA-supplied regions as well as of the anterior interventricular and circumflex branches the role of each coronary artery in supplying the left ventricle and the interventricular septum was elucidated in relation to a coronary supply type.
