A meta-analysis comparing bilateral internal mammary artery with left internal mammary artery for coronary artery bypass grafting

摘要

BackgroundIncreasing evidence continues to demonstrate a survival advantage for bilateral internal mammary artery (BIMA) over left internal mammary artery (LIMA) for coronary artery bypass grafting (CABG). We performed an updated meta-analysis of published studies comparing BIMA versus LIMA in CABG operations and assessed differences in long-term survival.
