Key result
Mitral-valve repair and chord-sparing replacement showed no significant difference in left ventricular reverse remodeling or 12-month survival in patients with severe ischemic mitral regurgitation.

Population
Severe ischemic mitral regurgitation
I
Intervention / Comparator
Mitral-valve repair (annuloplasty) vs Mitral-valve replacement (chord-sparing)
O
Primary Outcome
Left ventricular reverse remodeling and 12-month survival
Limitations
- Use of simple ring repair regardless of tethering severity may limit repair efficacy
- Definition of severe MR using EROA > 40 mm2 may have led to inclusion of patients with massive MR
- High rate (32%) of recurrent moderate-to-severe mitral regurgitation in the repair group
Cite This Study
Acker et al. (2014) conducted a letter in Severe ischemic mitral regurgitation. Mitral-valve repair (annuloplasty) vs. Mitral-valve replacement (chord-sparing) was evaluated on Left ventricular reverse remodeling and 12-month survival. Mitral-valve repair and chord-sparing replacement showed no significant difference in left ventricular reverse remodeling or 12-month survival in patients with severe ischemic mitral regurgitation.
