title: [Clinical evaluation of complications after implantation of stentless biological equine pericardial bioprothesis].
abstract: Stentless bio-protheses are more and more frequently used in patients with severe aortic stenosis, due to good hemo-dynamic parameters and durability after aortic valve replacement (AVR). Aim of the study was the clinical evaluation of complications after surgical AVR using the 3F equine pericardial stentless bioprothesis (ATS Medtronic, Inc, Minneapolis, USA).
  
  
  METHODS
  45 patients (10 women, 35 men), aged from 23 to 78 had implanted the bioprothesis.
  
  
  RESULTS
  Two patients died in perioperative period, but the bioprotehsis function was correct. In two patients gastrointestinal (GE) bleeding was observed due to anticoagulation therapy. In remaining 41 patients during one year follow-up no complications were noted.
  
  
  CONCLUSIONS
  After implantation 3F bioprotehesis two unrelated deaths and 2 GE bleeding complications were observed. Other 41 patients had no complications during 1 year follow-up.
