Total arterial coronary revascularization using arterial bypass circle with multiple inflows.
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.
