Abstract

Performing myocardial revascularization in patients with coronary artery disease (CAD) and atherosclerosis of the ascending aorta poses a significant challenge due to the high risk associated with the intervention. The literature describes a considerable number of technical modifications for coronary artery bypass grafting (CABG) using the “no-touch aorta technique.” This technique can be implemented, among other approaches, by utilizing proximal segments of the coronary arteries. This article presents the first experience with a coronary-coronary bypass procedure, where grafts were anastomosed between two segments of the same coronary artery. Intraoperative shuntography and ultrasonic flowmetry demonstrated 100% graft patency and favorable volumetric blood flow rates through the grafts. It is shown that coronary-coronary bypass grafting yields positive outcomes and can be considered a safe alternative for myocardial revascularization. Further studies are required to evaluate the efficacy of coronary-coronary bypass grafting in patients with CAD and atheromatosis of the ascending aorta.
