title: Perceval Sutureless Valve Dysfunction Caused by Valvular Thrombosis.
abstract: Until now, to our knowledge no case of bioprosthetic valvular thrombosis after implantation of the sutureless Sorin Perceval valve has been reported. Although sutureless aortic valve replacement has become a powerful tool in our daily practice, recent guidelines from the European Society of Cardiology, the European Association for Cardio-Thoracic Surgery, the American College of Cardiology, and the American Heart Association do not give specific recommendations on postoperative anticoagulation therapy. We report the first case of valve dysfunction resulting from thrombosis 12 months after implantation with a possible link to postoperative cortisole therapy.
