Off-pump Revascularization with Bilateral Mammary Artery -Single Center Proof of Concept after 5 Years

Objective: Off-pump myocardial revascularization using bilateral mammary artery (BIMA) is a promising concept in cardiac surgery during the last years. Beside proven benefits toward off-pump surgery, there is an ongoing debate, whether single mammary artery revascularization (SIMA) is superior to the BIMA revascularization in the short and long term course.
