IMA grafting was associated with better long-term angina freedom in reoperations; leaves open need for randomized confirmation.
Does internal mammary artery grafting improve freedom from recurrent angina and cardiac events compared to saphenous vein grafts alone in patients undergoing coronary reoperation for recurrent angina?
In patients undergoing coronary reoperation for recurrent angina, internal mammary artery grafting significantly improves long-term freedom from recurrent angina and cardiac events compared to saphenous vein grafts alone.
