AB  - Recently published studies suggest that the hemodynamic advantage of stentless 
      bioprostheses in comparison to stented bioprostheses positively influence the 
      long-term survival after aortic valve replacement. However, the more complex and 
      time consuming implantation technique may increase the risk of operative death. 
      Between April 1996 and September 2000, 201 patients with the mean age of 75 +/- 5 
      years underwent aortic valve replacement (AVR) with a stentless Medtronic 
      Freestyle Bioprothesis (FP) and 166 patients with a mean age of 77 +/- 5 years 
      received a stented Medtronic Mosaic Biopros thesis (MP). Patients requiring 
      concomitant procedures other than coronary artery bypass grafting (CABG) were 
      excluded. The operative mortality was 3.5% after AVR with the FP and 6% after AVR 
      with the MP. Multiple logistic regression analysis considering the different 
      patient populations revealed no increased risk of operative death after AVR with 
      FB (p = 0.46). Previously heart operations (p = 0.046) and emergency operation (p 
      = 0.022) were risk factors for operative death after AVR with the biological 
      bioprostheses. The risk for postoperatively neurological impairment (p = 0.15) 
      and other complications (p = 0.46) was furthermore not increased after 
      implantation of a Freestyle stentless valve. The risk of delayed mobilization (p 
      < 0.001) was 2.4-fold increased for patients after AVR with the Freestyle valve. 
      A positive influence on survival due to the implantation of a stentless Freestyle 
      valve could not be shown within the observed period. However, in spite of the 
      more complex and time-consuming operation technique, the risk of operative death 
      and postoperative complications is not increased after aortic valve replacement 
      with the stentless FB.
