[Aortic valve replacement with stentless bioprosthesis: surgical technique and early outcomes].

ABSTRACT

AIM: To evaluate prospectively the hemodynamic performance of «BiolAB Mono¼ stentless bioprosthesis implanted into aortic position. MATERIAL AND METHODS: Twenty seven patients (mean age 71 (67; 73); 17 women) with severe aortic stenosis underwent, aortic valve replacement with «BioLAB Mono¼ stentless bioprosthesis from 2012 to 2014. The valves- were implanted into supraannular position using continuous polypropylene suture. RESULTS: In the early postoperative period 1 patient (3.7%) died for acute heart failure. The mean aortic cross-clamping time was 81 (75; 90) min. Echocardiographic peak pressure gradient were 18 (16;23) mmHg (postoperative). There were no cases of valve dysfunction In early 'postoperative period. Level of thrombocytes recovered after 1 O days postoperatively. CONCLUSION: «BioLAB Mono¼ aortic bioprosthesis implantation. is easy and reproducible. The valve has excellent hemodynamic performance ir;i early postoperative period.
