Key result
Percutaneous coronary intervention with stenting successfully restored TIMI 3 blood flow in an occluded left internal mammary artery graft in a patient with recurrent anterior myocardial infarction.
Why the study?
Even when using the internal mammary artery for CABG, graft failure can occur, requiring vigilance and potential endovascular intervention.
Case Report (n=1)
PCI of an occluded internal mammary artery graft is a feasible and effective strategy for treating recurrent myocardial infarction in post-CABG patients.
PCI of occluded LIMA may be feasible in recurrent post-CABG MI; leaves open need for larger studies before practice change.
Coronary artery bypass grafting (CABG) is the most preferred method of myocardial revascularization in multivessel coronary artery disease and severe progressive forms of the disease. The material of choice for CABG of the left anterior descending artery (LADA) is the internal mammary artery (IMA). However, even when using IMA as a conduit for CABG, one should be aware of a possibility of graft failure, which indicates a need for constant vigilance in this category of patients. Endovascular interventions on coronary arteries make it possible to efficiently and safely revascularize an occluded bypass graft, minimizing existing risks and improving both the quality of life of patients and their subsequent survival. The article considers a clinical case of the development of recurrent anterior myocardial infarction in the patient due to occlusion of the mammary graft to the LADA.

Zakharyan et al. (2023) conducted a case report in Recurrent anterior myocardial infarction due to LIMA graft occlusion (n=1). Percutaneous coronary intervention with stenting was evaluated on Restoration of graft patency. Percutaneous coronary intervention with stenting successfully restored TIMI 3 blood flow in an occluded left internal mammary artery graft in a patient with recurrent anterior myocardial infarction.
