Why the study?
Does preoperative posterior leaflet angle predict postoperative persistence of MR and event-free survival in patients undergoing restrictive annuloplasty for ischemic MR?
Population
51 consecutive patients undergoing restrictive annuloplasty for ischemic mitral regurgitation
Comparison
Preoperative echocardiographic assessment of… vs Preoperative PL angle < 45 degrees
Design
Cohort
Follow-up
3 years
Key result
A preoperative posterior leaflet angle ≥45 degrees accurately predicted persistence of mitral regurgitation and was associated with lower 3-year event-free survival (22% vs 76%, P<0.001).

May support preoperative risk stratification for persistent MR after annuloplasty; leaves open whether angle informs surgical strategy.

Does preoperative posterior leaflet angle predict postoperative persistence of MR and event-free survival in patients undergoing restrictive annuloplasty for ischemic MR?
Absolute Event Rate: 22% vs 76%
p-value: p=<0.001
Preoperative echocardiographic measurement of posterior leaflet angle ≥ 45 degrees accurately identifies patients at high risk for persistent MR and poor outcomes after restrictive annuloplasty for ischemic MR.
Magné et al. (2007) conducted a cohort in Ischemic mitral regurgitation (n=51). Preoperative posterior leaflet angle ≥ 45 degrees vs. Preoperative posterior leaflet angle < 45 degrees was evaluated on 3-year event-free survival (p=<0.001). A preoperative posterior leaflet angle ≥45 degrees accurately predicted persistence of mitral regurgitation and was associated with lower 3-year event-free survival (22% vs 76%, P<0.001).
