Reoperation for a patient 25 years after a Starr-Edwards ball mitral valve was installed

A 45-year-old female suffered from increasing dyspnea during exercise and edema of lower extremities from January 2000. She had undergone mitral valve replacement with Starr-Edwards ball prosthesis (model 6320) due to mitral valve regurgitation 25 years ago. The cardiac catheterization and echocardiography documented mitral, aortic and tricuspid valves regurgitation grade III. Left ventricular ejection fraction rate was 49% and the pressures of CVP, RA, RV and PA were also increased. Laboratory examination showed slight hemolytic anemia. Double valve replacement (ATS valve) and tricuspid annuloplasty were carried out in April 2000. Strut cloth wear was confirmed at operation. Her postoperative course was uneventful. We hereby review the published paper of all cases with an implanted Starr-Edwards ball valve who required redo valve replacement with over 15 years follow-up. We consider that cloth injury is the main cause for reoperation and it usually associated with hemolytic anemia; cloth wear not only involves the aortic position but also frequently involves the mitral position for over 15 years follow-up patients and can be corrected by reoperation. Cloth wear should be concerned for those surviving patients who have received the Starr-Edwards ball valve during long-term follow-up.
