The first experience of implantation of the transcatheter aortal valve prosthesis “MedLab-KT”

Abstract

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.
