Why the study?
Does edge-to-edge mitral valve repair without annuloplasty provide satisfactory long-term outcomes in patients with degenerative mitral regurgitation?
Population
61 patients with degenerative mitral regurgitation treated between 1993 and 2002. Annuloplasty was omitted…

Cohort
Follow-up
mean 9.2±4.21 years; median 9.7 years; longest 18.1 years
Key result
Edge-to-edge mitral repair without annuloplasty for degenerative MR showed unsatisfactory long-term results; residual MR >1+ at discharge predicted recurrence of MR ≥3+ (HR 3.8; 95% CI 1.7-8.2).

Does not support routine edge-to-edge repair without annuloplasty in degenerative MR; leaves open whether annuloplasty addition improves durability.

Surgical edge-to-edge mitral valve repair without annuloplasty for degenerative MR yields unsatisfactory long-term results, with high rates of recurrent severe regurgitation.
Bonis et al. (2014) conducted a cohort in Degenerative mitral regurgitation (n=61). Edge-to-edge mitral repair without annuloplasty was evaluated on Recurrence of MR ≥3+ (HR 3.8, 95% CI 1.7-8.2, p=0.001). Edge-to-edge mitral repair without annuloplasty for degenerative MR showed unsatisfactory long-term results; residual MR >1+ at discharge predicted recurrence of MR ≥3+ (HR 3.8; 95% CI 1.7-8.2).
