The authors present early results in a comparative study using one or two internal thoracic arteries for myocardial revascularization. They find no difference in both groups, regarding hospital mortality or morbidity. Angiographic study showed that early patency of the right internal thoracic artery passed through transverse sinus is similar to the left internal thoracic artery; is also better than saphenous vein grafts. They conclude that the double internal thoracic artery can be used more aften in selected patients.
