Key result
Mitral valve repair for mitral valve disease demonstrated a 3% operative mortality and a 10-year actuarial survival of 67%, with previous myocardial infarction predicting poor outcome (OR 13.7).
Population
94 patients with mitral valve disease (59% degenerative, 30% rheumatic), mean age 49 years, 50% male.
Design
Cohort
Follow-up
up to 10 years

May inform surgical risk assessment in mitral disease; leaves open prior MI impact on outcomes pending prospective validation.
Cohort (n=94)
Mitral valve repair demonstrates favorable long-term survival and freedom from reoperation, though previous myocardial infarction is associated with poorer outcomes.
Xu et al. (1994) conducted a cohort in Mitral valve disease (n=94). Mitral valve repair was evaluated on 10-year actuarial survival. Mitral valve repair for mitral valve disease demonstrated a 3% operative mortality and a 10-year actuarial survival of 67%, with previous myocardial infarction predicting poor outcome (OR 13.7).
