title: Isolated mitral valve replacement with the Björk-Shiley prosthesis in 100 consecutive patients. Short- and long-term results.
abstract: Single mitral valve replacement with the Björk-Shiley tilting disc prosthesis was performed in 100 consecutive patients between March 1971 and December 1973. The hospital mortality was 13% and the late mortality was 6%. 74 of the patients were followed for periods ranging between 12 and 46 months (mean follow-up: 24 months): clinical improvement was noted in 92%. The incidence of postoperative embolism, including 1 case of prosthesis thrombosis, was 6.7%, and all cases occurred within the first 9 months after surgery. 6 patients required reoperation because of prosthesis dysfunction due to thrombosis (1 patient), leakage (3), and late disc entrapment (2).
