Key result
Less than moderate residual mitral regurgitation after mitral valve repair was associated with a non-significant trend toward higher in-hospital death or reintervention compared to no residual regurgitation (13.6% vs 5.5%, p=0.31).
Why the study?
Does less than moderate residual mitral regurgitation increase the risk of death or reintervention compared to no residual mitral regurgitation in patients undergoing isolated mitral valve repair?
Cohort (n=98)
No

Less than moderate residual mitral regurgitation after mitral valve repair showed a non-significant trend toward higher early adverse outcomes compared to no residual MR, suggesting that even mild residual MR may warrant closer attention.
Rizza et al. (2007) conducted a cohort in Mitral regurgitation (n=98). Less than moderate residual mitral regurgitation vs. No residual mitral regurgitation was evaluated on Composite of in-hospital death or need of reintervention for recurrent severe mitral regurgitation (p=0.31). Less than moderate residual mitral regurgitation after mitral valve repair was associated with a non-significant trend toward higher in-hospital death or reintervention compared to no residual regurgitation (13.6% vs 5.5%, p=0.31).
