From April 1983 to November 1993,185 patients were submitted to myocardial revascularization using bilateral thoracic internal artery. The left internal thoracic artery was used to left anterior descending artery and the right internal thoracic artery was used through transversus sinus to circunflex artery and his branches. We performed 38 angiographic studies during the late follow-up and demonstrated that the right internal thoracic artery was patent in 29 patients (92.7%) and the left internal thoracic artery in 30 (97%). We conclude that myocardial revascularyzation should be performed using bilateral internal thoracic artery routinely.
