Implantation of a mechanical valve in a previously implanted mitral bioprosthetic orifice in a patient with mitral bioprosthetic failure

Abstract

Complete removal of a previously implanted dysfunctional mitral bioprosthesis could result in extensive damage. Therefore, a 66-year-old female patient with a deteriorated mitral bioprosthesis had leaflet excision, and a "new" mechanical valve was sewn onto the previously implanted bioprosthetic sewing cuff. On postoperative echocardiography, the implanted valve had good hemodynamic performance with no paravalvular leakage. The patient's clinical condition improved after surgery.
