Key result
Mitral valve repair yielded comparable midterm survival in patients with ischemic mitral regurgitation compared to nonischemic mitral regurgitation, with 3-year survival rates of 82.4% and 90.3%, respectively.
Why the study?
Does mitral valve repair yield comparable early and midterm mortality in patients with ischemic versus nonischemic mitral regurgitation?
Cohort (n=82)
Does mitral valve repair yield comparable early and midterm mortality in patients with ischemic versus nonischemic mitral regurgitation?
Absolute Event Rate: 82.4% vs 90.3%
p-value: p=0.379
Mitral valve repair provides comparable midterm results for both ischemic and nonischemic mitral regurgitation, with long-term survival influenced more by baseline comorbidities like diabetes and renal insufficiency than the ischemic etiology itself.
May support mitral valve repair across etiologies; leaves open comorbidity effects on survival in prospective trials.

Lukacín et al. (2011) conducted a cohort in Mitral regurgitation (n=82). Ischemic etiology of mitral regurgitation vs. Nonischemic etiology of mitral regurgitation was evaluated on 3-year cumulative survival (p=0.379). Mitral valve repair yielded comparable midterm survival in patients with ischemic mitral regurgitation compared to nonischemic mitral regurgitation, with 3-year survival rates of 82.4% and 90.3%, respectively.
