Abstract:
The paper presents current principles in designing diagnostic coronary angiography by taking into account of fundamental achievements in endovascular medicine in diagnosing and treating various heart diseases. Analyzing the world and Russian experience gained, the authors present basic qualitative and quantitative requirements for X-ray contrast study of cardiac vessels to enhance the information value of coronary angiography. They consider necessary diagnostic criteria to be achieved during the study to choose a surgical or endovascular treatment: a type and number of diagnostic film projections, X-ray anatomy of coronary vessels. The present-day accumulated data on X-ray anatomic features of coronary vessels in coronary heart disease are classified. Current classifications of coronary circulation, principles in the development of collateral blood supply, main sources of collaterals, and the specific features of the coronary bed in patients with coronary heart disease are also given.
