Mitral valve re-replacement in a patient with osteogenesis imperfecta.

A 34-year-old patient with osteogenesis imperfecta (OI) underwent previous double-valve replacement in the aortic and mitral valve position. Bioprostheses were implanted because of an elevated risk of daily injury. Five years later the patient underwent re-replacement of the stenotic stentless mitral valve prosthesis. A right anterolateral mini-thoracotomy was used for operative access during both procedures, in order to preserve thorax stability. Patients with OI may benefit from minimally invasive valve surgery for primary procedures or reoperation. © Georg Thieme Verlag KG Stuttgart · New York.
