Rita-Rae (Right Internal Thoracic Artery to Radial Artery Extension): Experience With Total Arterial Revascularisation Without Aortic Anastomoses

Abstract

Total arterial revascularisation using internal thoracic and radial arteries are emerging as desirable long-term solutions for triple vessel coronary artery disease (CAD). Achieving this goal can sometimes be challenging due to a shortage of available arterial conduit, need for aortic anastomoses, limited length of conduits, and optimal use. This study explored a novel configuration of connecting the radial artery graft to the distal end of the right internal thoracic artery (RITA) as an adjunct to the conventional left internal thoracic artery (LITA) to left anterior descending (LAD) graft.
