title: Early bioprosthetic mitral valve "pseudostenosis" after complete preservation of the native mitral apparatus.
abstract: An advantage of bioprosthetic mitral valve replacement in patients with normal sinus rhythm is avoidance of the need for long-term anticoagulation. Bioprosthetic valve thrombosis is a rare complication, supporting this approach. This case report represents an example of porcine mitral valve stenosis, likely secondary to thrombosis, in which all of the native mitral valve apparatus was left intact. This was successfully treated with standard anticoagulation therapy. This complication should be considered in patients in whom retention of the mitral valve apparatus has been performed. Such patients may benefit from long-term anticoagulation treatment to obviate this event.
