You may qualify if:

  • patients with isolated valvular aortic stenosis or combined aortic-valve defect with prevailing stenosis with severe bleeding during aortic-valve replacement

You may not qualify if:

  • active endocarditis
  • history suggestive for inherited oe acquired bleeding disorder
  • concomitant coronary heart disease
  • agents impairing platelet function up to 14 days before surgery
  • Pregnancy
  • inherited platelet function
