Figure 2 Independent Associations Between MV Surgical Treatment and Outcome in 394 Patients With Flail Leaflet

Time-dependent analysis shows favorable associations between MV surgery and outcome in patients (n = 394) with degenerative MR due to flail leaflet (after adjusting for age, New York Heart Association functional class, and left ventricular ejection fraction. The results support the rationale for considering MV surgery early in the course of the disease. Cases of perioperative (i.e., <30 days) AFib (n = 24) were excluded from the analysis. Point estimates of hazard ratios (HRs) are graphically depicted as circles, with their 95% confidence intervals (CI) (lines). Abbreviations as in Figure 1.
