Does Björk-Shiley mitral valve replacement improve long-term survival and functional status in patients requiring mitral valve replacement?
While early valve-related complications were high, long-term survival and functional outcomes of the Björk-Shiley mitral valve were comparable to other mechanical valves.
Harjula et al. (1986) conducted a cohort in Mitral valve replacement (n=176). Björk-Shiley mitral valve replacement was evaluated on 10-year and 5-year survival rates. Björk-Shiley mitral valve replacement demonstrated 10-year and 5-year survival rates of 79%, with functional status improving in 77.1% of patients despite a high incidence of early complications.
