Mid-Term Outcomes After Bilateral Versus Single Internal Mammary Artery Grafting in MIDCAB

In this single-center propensity-matched analysis of 659 patients undergoing minimally invasive direct coronary artery bypass (MIDCAB), bilateral internal mammary artery grafting achieved short- and mid-term clinical outcomes comparable to single internal mammary artery grafting. These findings support its feasibility in minimally invasive coronary revascularization, while highlighting the need for longer-term follow-up to determine potential durability benefits.
