The first experience of transcatheter implantation of aortic valve prosthesis «Medlab-KT» in the Far Eastern federal district

Abstract

The results of transcatheter implantation of the fi rst Russian aortic valve prosthesis «MedLab-CT» are
 presented in the article. Transapical aortic valve implantation with MedLab-CT prosthesis was performed in 28 patients
 with a high surgical risk of severe aortic stenosis and concomitant pathology (EuroScore II 5,44). The operations were
 performed in a hybrid operating room, and the average duration time was 90 minutes. Concomitant stent-assisted coronary
 intervention was conducted in three patients. There were no cases of conversion to artifi cial blood circulation. At
 the hospital stage, two patients (7 %) died due to multiple organ failure that developed after surgery. Two patients (7 %)
 required an implantation of a permanent pacemaker. There were no cases of migration and dislocation of the prosthesis
 and rethoracotomy. The mean gradient on the valve was 6 mmHg, the maximum was 12 mmHg. The signifi cant
 intravalvular and paraprosthetic regurgitation was not observed. The average stay in the intensive care unit was about
 one day and approximately 12 days in the surgical department after the operation. The fi rst experience of implantation
 of a transcatheter «Medlab-CT» aortic prosthesis in the Far East Federal District allows making a conclusion that we
 obtained good clinical and hemodynamic results, which are consistent with the results of other authors using this valve.
