Key result
LIMA versus SVG for isolated LAD stenosis lacks specific reported outcomes.
Why the study?
Do left internal mammary artery grafts improve survival, graft patency, and functional class compared to saphenous vein grafts in patients with isolated left anterior descending coronary artery stenosis?
Cohort (n=200)
Do left internal mammary artery grafts improve survival, graft patency, and functional class compared to saphenous vein grafts in patients with isolated left anterior descending coronary artery stenosis?
Revascularization can be recommended selectively for patients with critical isolated LAD stenoses who have limiting symptoms and large areas of viable myocardium at risk.
Supports individualized conduit selection for isolated LAD disease; leaves open conduit superiority in randomized settings.
A consecutive series of 100 patients receiving left internal mammary artery grafts and a consecutive series of 100 patients receiving saphenous vein grafts as treatment of isolated left anterior descending coronary artery stenosis were reviewed to determine survival, graft patency, disease progression and New York Heart Association functional class. The mean follow-up was 67 months, and the mean catheterization interval was 20 months. Recommendations for revascularization can be made selectively to patients with critical isolated left anterior descending stenoses who have limiting symptoms and large areas of viable myocardium at risk.

Lytle et al. (1980) conducted a cohort in Isolated left anterior descending coronary artery stenosis (n=200). Left internal mammary artery grafts vs. Saphenous vein grafts was evaluated on Survival, graft patency, disease progression and New York Heart Association functional class.
