Delayed dislocation of a sutureless aortic bioprosthesis: the first case.

Sutureless aortic bioprosthesis implantation is an alternative technique in high-risk patients undergoing aortic valve replacement with a possible reduction in the extracorporeal circuit time and reliable haemodynamic features. A 3F Enable (ATS Medical-Medtronic, Inc., Minneapolis, MN, USA) has shown very good results. We report the first upward displacement of 3F Enable three months post implantation.
