A clinical case of myocardial infarction after coronary artery bypass grafting using the internal mammary artery

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.
