Abstract

BACKGROUND: Total arterial revascularisation may prolong postoperative survival following coronary surgery due to avoidance of late saphenous vein graft (SVG) failure leading to ischaemic cardiac events. The left internal mammary artery (LIMA) is routinely used for CABG but harvest may adversely affect lung function and reduce sternal vascular supply. Early experience of a novel reconstruction with exclusive reliance on two radial arteries (RA) joined as a Y graft (RARAY) is presented. METHODS: One RA is anastomosed to the ascending aorta and used to revascularise the left anterior descending artery coronary territory; and a second RA is joined to the first 4-6 cm from the origin, approximat..
