What is LIMA Coronary Bypass? Definition and Benefits

Coronary artery bypass grafting with the Left Internal Mammary Artery (LIMA) is a top choice in heart surgery. It uses the LIMA to connect to the left anterior descending artery (LAD). This helps to bypass blocked or damaged areas and restore blood flow to the heart.
The LIMA graft is chosen because of its superior long-term patency rates and improved patient outcomes. Research shows that patients with LIMA grafts live longer and have fewer heart problems than those with other grafts.
The Left Internal Mammary Artery: A Preferred Conduit
The Left Internal Mammary Artery is a key branch of the subclavian artery. It’s favored for CABG because of its proximity to the heart and resistance to atherosclerosis. We use it to bypass the LAD, a vital artery for the heart.
Anatomical Advantages of Using LIMA for CABG
Using LIMA for CABG offers many benefits. Its length and diameter are perfect for grafting to the LAD. Plus, its natural resistance to atherosclerotic disease lowers the risk of graft failure. These factors lead to high patency rates with LIMA grafts.
By choosing LIMA grafting in CABG, we can greatly improve patient results. It also cuts down on the need for more surgeries. LIMA grafting is a key part of treating coronary artery disease.
