title: [Changes in the angioarchitectonics of the heart in sudden coronary death].
abstract: Changes in cardiac angioarchitectonics were studied in 60 cases of sudden coronary death and in 20 controls by means of multiprojection, quantitative coronarography and WHO standard anatomic method. A significant rate (60%) of stenotic atherosclerotic and dilatational (40%) changes was revealed in 3 major coronary arteries. Rearrangement of collateral circulation with the development of myocardial hypervascularization signs was found in 53.3% of cases, with the formation of "new" coronary path ways in 26.7%, and complete bypass blood flow in 20% of cases. Frequent stenoses of the anterior branch of the interventricular septum and sinus node artery were revealed, as well as intramural localization of the anterior interventricular artery due to myocardial muscular bridges, decrease of vascularization density in the left ventricular posterior wall myocardium and septum.
