Arterial coronary artery bypass grafting is safe and effective in elderly patients.

Objectives: Bilateral internal thoracic artery grafting in elderly patients is controversial. We compared the outcome of bilateral internal thoracic artery grafting with that of single internal thoracic artery and saphenous vein and radial artery conduits in these patients.

Methods: Patients aged 70 years or more who underwent bilateral internal thoracic artery grafting between 1996 and 2008 (n = 1045) were compared with patients who underwent coronary artery bypass grafting with a single internal thoracic artery + saphenous vein graft (n = 582) or a single internal thoracic artery + radial artery (n = 249).
