My colleagues and I present a method for revascularizing the left anterolateral myocardial wall by using an in situ left internal thoracic artery to left anterior descending coronary artery system and a short proximal segment (3 to 5 cm) of the right internal thoracic artery in Y fashion anastomosed to the in situ left internal thoracic artery to revascularize the obtuse marginal branches. With this technique the left ventricular anterolateral wall can be revascularized with both internal thoracic arteries, leaving a consistent residual blood supply to the right hemisternum.
