Coronary artery bypass techniques, currently applied to maximize the benefits of multiple arterial coronary conduits, render the newly constructed myocardial flow dependent on a single source "inflow" of blood. We describe a technique for total arterial coronary revascularization with multiple inflows; the distal end of the pedicled right internal thoracic artery is anastomosed to the distal end of a free radial artery, and the other end of the radial artery is then connected to the ascending aorta. This vascular circle, passed in a retro-cardiac fashion, is used to revascularize the inferio-lateral surface of the heart using multiple side-to-side anastomoses. The "sacred" left internal thoracic artery is reserved to revascularize the anterior wall of the myocardium, independent of the arterial circle.
