Key result
Isolated mitral valve repair for degenerative disease resulted in higher 5-year survival compared to repair with concomitant procedures (92% vs. 76%; p<0.001).
Why the study?
What are the long-term clinical and echocardiographic outcomes after mitral valve repair for degenerative disease?

Mitral valve repair for degenerative disease provides excellent 5-year survival and low rates of recurrent severe mitral regurgitation, though concomitant procedures are associated with higher mortality and recurrence risk.
No takes yet. Share an insight, caveat, or question.
Supports isolated repair when feasible in degenerative disease; leaves open whether concomitant procedures independently worsen outcomes.
Stevens et al. (2009) conducted a cohort in Severe degenerative mitral regurgitation (n=403). Isolated mitral valve repair vs. Mitral valve repair with concomitant procedure was evaluated on 5-year survival (p=<0.001). Isolated mitral valve repair for degenerative disease resulted in higher 5-year survival compared to repair with concomitant procedures (92% vs. 76%; p<0.001).
