Population
24 patients who had undergone mitral valve surgery for pure non-rheumatic mitral regurgitation
Design
Cohort
Follow-up
6 months to 6 years postoperatively
Key result
Preoperative factors including symptomatic history <1 year, LVEDVI ≤100 ml/m2, ejection fraction ≥0.5, and use of a Björk-Shiley prosthesis were prime determinants of a good long-term surgical outcome.

May inform surgical timing in non-rheumatic MR; leaves open prospective validation of thresholds.
Observational (n=24)
Surgery for non-rheumatic mitral regurgitation should ideally be performed within one year of symptom onset and before left ventricular end-diastolic volume index exceeds 100 ml/m2 or ejection fraction falls below 0.5 to ensure optimal long-term outcomes.
Saltissi et al. (1980) conducted an observational in Non-rheumatic mitral regurgitation (n=24). Preoperative and intraoperative prognostic factors was evaluated on Long-term surgical outcome (good vs poor response). Preoperative factors including symptomatic history <1 year, LVEDVI ≤100 ml/m2, ejection fraction ≥0.5, and use of a Björk-Shiley prosthesis were prime determinants of a good long-term surgical outcome.
