Key result
Recurrent mitral regurgitation after mitral valve repair for functional ischemic MR was independently associated with an increased mortality risk (HR 3.28; 95% CI 1.87-5.75; P<0.001).
Why the study?
Recurrent mitral regurgitation occurs after mitral valve repair for functional MR, but its impact on long-term survival remains poorly defined.
Does recurrent mitral regurgitation impact long-term survival in patients who underwent mitral valve repair for functional ischemic mitral regurgitation?

Hazard Ratio: 3.28 (95% CI 1.87–5.75)
p-value: p=< 0.001
Recurrent mitral regurgitation after mitral valve repair for functional ischemic MR is independently associated with a more than 3-fold increased risk of long-term mortality.
No takes yet. Share an insight, caveat, or question.
Recurrent MR signals higher mortality risk after ischemic functional MR repair; extends observational associations but leaves open whether targeting recurrence alters outcomes.
Petrus et al. (2019) conducted a cohort in Functional mitral regurgitation in the setting of ischaemic heart disease (n=261). Recurrent mitral regurgitation vs. No recurrent mitral regurgitation was evaluated on Mortality risk (HR 3.28, 95% CI 1.87-5.75, p=< 0.001). Recurrent mitral regurgitation after mitral valve repair for functional ischemic MR was independently associated with an increased mortality risk (HR 3.28; 95% CI 1.87-5.75; P<0.001).
