Abstract
Percutaneous coronary interventions (PCI) on the left main coronary artery (LMCA) are high-risk interventions due to large volume of the myocardium supplied with blood by the target artery. With the improvement of stenting technique and the introduction of new tools, there is a gradual expansion of indications for PCI in patients with LMCA lesion. This localization of the lesion causes a high risk of intervention due to the frequent involvement of the trunk bifurcation in the atherosclerotic process, which requires the use of more complex stenting techniques. Intravascular imaging is an important additional option that helps optimize immediate and long-term results of PCI on LM. Currently, the use of optical coherence tomography (OCT) in the treatment of LMCA lesions, despite all the advantages of the method, is limited. This is due to the lack of experience in using the method and the difficulty of obtaining OCT slices of good quality at the LM level. This article presents clinical examples of successful use of OCT during PCI on LMCA lesions. In these examples, the use of OCT provides more comprehensive information about the immediate result of stenting and facilitates the choice of further intervention tactics, while an unambiguous interpretation of the angiographic result was difficult.References
