Aim:
To evaluate prospectively the hemodynamic performance of «BioLAB Mono» 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 Mono» stentless bioprosthesis from 2012 to 2014. The valves were implanted into supra-annular 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 10 days postoperatively.
Conclusion:
«BioLAB Mono» aortic bioprosthesis implantation is easy and reproducible. The valve has excellent hemodynamic performance in early postoperative period.
