We analyzed 50 aortic valve replacements (AVR) with Kemerovo-AB-Neo stentless bioprostheses. Mean age was 66.75 (54 to78) years, hospital mortality rate accounted for 2%. The peak transprosthetic pressure gradient (PTPG) in patients operated for aortic stenosis came to 19.57 mm Hg. PTPG was shown to be dependent on the implantation technique; it reached 24.57 mm Hg when in order to fix the proximal line, interrupted sutures were used and ran to 175 mm Hg in the case of running sutures (р = 0.03). Helical CT confirmed fine mobility of the cardiac structures after Kemerovo-AB-Neo implantation: the aortic cross-section area varied up to 84% during the cardiac cycle. It should be noted that AVR with Kemerovo-AB-Neo stentless valves gives good clinical and hemodynamic results early after surgery. A free-hand technique of implantation should be preferred. The implantation of stentless bioprostheses retains cardiac structures mobility and natural aortic root dimensions after performing an AVR.
