Aim. Transcatheter aortic valve replacement in patients with high and extremely high risk has become a routine procedure in many cardiac surgery clinics. Until recently, there were no transcatheter prostheses produced within Russia. This article analyzes the results of applying the first domestic transcatheter aortic valve prosthesis MedLab­KT. Material and methods. In the period from June 2018 to October 2018, 7 operations of transcatheter aortic valve replacement were made using the MedLabKT prosthesis. In all cases, implantation was performed by transapical access.Results. We noted one death. In all cases, paraprosthetic regurgitation was not registrated or was not significant. There are no cases of dislocation of the prosthesis. There were no complications associated with access. In one case, implantation was complicated by myocardial infarction.Conclusion. The first experience of implantation demonstrated the efficacy and safety of using the MedLab­LT prosthesis for transcatheter aortic valve replacement. The analysis of long­term results is required.

This literature review focuses on the choice of treatment strategies in patients with aortic stenosis. The main surgical techniques for this condition are presented. The rationale for the efficiency of transcatheter aortic valve implantation is provided. The results of studies comparing the outcomes of surgical and endovascular correction of aortic stenosis are analyzed. Particular attention is paid to the treatment choices in patients with aortic stenosis and a history of coronary artery bypass grafting. Conclusions on the perspectives of transcatheter aortic valve implantation in this cohort of patients are reached.
