Reoperation for Starr-Edwards Ball Valve Insufficiency 21 Years after Replacement / 日本心臓血管外科学会雑誌

ABSTRACT

A 51-year-old woman, who had undergone mitral valve replacement with the Starr-Edwards ball valve 21 years ago, was hospitalized with cardiac failure. Preoperative cineangiograms showed delay of the ball movement during the early diastolic phase. Re-replacement of the mitral prosthetic valve with a CarboMedics prosthetic valve and tricuspid annuloplasty was successfully performed. The postoperative period after the initial implantation of the Starr-Edwards ball valve is the longest among patients reported in Japan. The cause of prosthetic valve insufficiency may have been granulomatous hyperplasia on the valve seat.
