Functioning of aortocoronary bypass grafts depending on the lesion and on the anatomical characteristics of coronary arteries

Abstract

Aortocoronary bypass grafting is a reliable and effective method of treatment for ischemic heart disease. Despite a well-defined spectrum of the used grafts, many tactic issues of aortocoronary bypass grafting remain unsolved. There is a lack of a unified classification of lesions in the native coronary vasculature; this prevents from establishing objective indications to direct myocardial revascularization and excludes any further improvement of surgical results. The strategy to bypass the maximal number of occluded coronary arteries irrespective on the patient’s age and the degree of coronary pathology could not be considered the most optimal in the absence of objective methods of post-operative diagnosis.
