Off-Pump Coronary Artery Bypass With Bilateral Internal Mammary Arteries

Editorial note: The video in version 1 of this article is of disputed ownership. Version 2 or later should be referenced.

The bilateral internal mammary arteries technique for off-pump coronary artery bypass is a safe technique with long-term patency and low morbidity and mortality. The author usually uses total arterial myocardial revascularization using bilateral internal mammary arteries for patients younger than 75 years old. The left and right mammary arteries have the longest patency described of any type of graft that can be use in cardiac surgery.

Left and right mammary artery composite Y-grafts were constructed using 8-0 Prolene® sutures. The author uses the same suture line in each anastomosis. The use of bilateral internal mammary arteries for myocardial revascularization has become the standard technique according to recent guidelines.
