To the Editor:
We would like to thank Foroughi and colleagues [1] for their discussion and stimulating comments.
We agree that more focused evaluation between pedicled or skeletonized left internal mammary artery (LIMA) grafts should be related to endpoints that directly refer to the conduit itself or to the downstream myocardium. Anterolateral myocardial kinetics reflect LIMA to left anterior descending coronary artery (LAD) function. Perioperative troponins relate to both the effectiveness of myocardial revascularization and the quality of myocardial protection. However, when hospital outcomes are considered enzymatic leakage, myocardial functional recovery and the incidence of perioperative acute myocardial infarction (AMI) must be considered. Moreover, collateral circulation in patients undergoing three-vessel revascularization [2] may mask graft malfunction in the territory supplied by the graft.
