A review of evidence suggests bilateral internal mammary artery (BIMA) grafts for coronary revascularisation improve survival compared to a single internal mammary artery with saphenous vein grafts.
Does bilateral internal mammary artery grafting improve survival compared to single internal mammary artery grafting in patients undergoing coronary revascularisation?
This review highlights the survival benefits of bilateral internal mammary artery grafting over single internal mammary artery grafting and provides technical guidance to encourage its broader adoption.
Bilateral internal mammary artery (BIMA) grafts are used for coronary revascularisation by only a minority of surgeons, despite a growing body of evidence suggesting improved survival when compared to use of only one internal mammary artery with additional saphenous vein grafts. Herein we review the evidence supporting revascularisation with BIMA and suggest reasons why the majority of surgeons use only one internal mammary artery. We discuss technical considerations, various graft combinations and the use of BIMA to facilitate anaortic off-pump coronary artery bypass (OPCAB).
Vallely et al. (Mon,) conducted a review in Coronary revascularisation. Bilateral internal mammary artery (BIMA) grafts vs. Single internal mammary artery with additional saphenous vein grafts was evaluated on Survival.
