Purpose of review Ongoing efforts to compare percutaneous coronary intervention with coronary bypass surgery for multivessel coronary disease mandate that surgeons reevaluate best practices for coronary surgery in order to maximize long-term outcomes. This review presents recent data for the long-term outcomes of multiple arterial grafting in terms of patient selection, conduit choice, and technical considerations. Recent findings Multiple arterial grafting remains poorly utilized, with fewer than 10% of cases receiving more than one arterial graft. Bilateral internal thoracic artery grafting confers superior long-term survival and freedom from reoperation over single thoracic artery with saphenous vein. Use of a second internal thoracic artery graft is advantageous in diabetic patients despite higher risk of sternal wound complications. Routine use of skeletonized grafts and Y or T grafting to allow complete revascularization allows lower early complication rates and better long-term survival. Radial artery grafts confer superior long-term survival compared with saphenous vein grafts and should be considered in patients at high risk for sternal wound complications. Summary Multiple arterial grafting confers superior long-term outcomes in comparison with single internal thoracic artery grafting and should be considered as the standard of care.
