title: [Prospective modeling of coronary bypass surgery].
abstract: Operation for mammary-coronary shunting was reproduced on experimental dogs. Myocardial perfusion during shunting was accomplished through a shunt, passing in the mammary artery and introduced into the distal part of the coronary artery through an incision. This allowed the use of extracorporeal circulation and the development of myocardial ischemia to be avoided. The method makes it possible to create stenoses in any part of the vascular block. The authors analysed the dependence between the coronary blood flow and the pressure in the left ventricle and aorta by means of a mathematical model, which made it possible to separate the effect produced on the coronary blood flow by such parameters as the resistance and capacity of the large vessels, resistance of small vessels, pressure of arrest of the blood flow, and extravascular compression.
