[Elaboration of criteria for selection of patients with chronic ischemic heart disease for direct myocardial revascularization surgery].
Indications for direct myocardial revascularization were specified on the basis of a new parameter: the disrupted myocardial blood supply zone (DBSZ). Absolute indications for the procedure included: a more than 50% narrowing in the diameter of the main trunk of the left coronary artery; two or 3 vessels affected with the DBSZ accounting for at least 75% of the left-ventricular and interventricular-septum weight. Relative indications included: two or three affected vessels with the DBSZ covering between 50 and 75% of the left-ventricular and interventricular-septum weight; and a more than 50% isolated proximal narrowing of the diameter of the anterior interventricular branch with any type of coronary blood supply, of the right coronary artery, with types 10:10 and 11:9, and of the circumflex branch, with types 5:15 and 6:14.
