2. Fig 1
Study population. Of 3,383 patients with isolated posterior leaflet prolapse, mitral valve repair was performed in 96.7%, and 3,074 underwent a standard repair that included quadrangular resection and annuloplasty. These patients represent the study group.

Mean age of patients undergoing repair of posterior leaflet prolapse as a function of time. Closed circles represent yearly age estimates. Solid line is trend line.

4. Fig 3
Death after mitral valve repair for posterior leaflet prolapse compared with expected survival of an age- and sex-matched US population cohort (dot-dash-dot line). Each circle represents a death, vertical bars are asymmetric 68% confidence limits (CL, equivalent to ± 1 standard error), solid line is parametric estimate enclosed within dashed 68% CLs, and numbers in parentheses are patients remaining at risk. (A) Survival. (B) Hazard function (instantaneous risk) for death. Solid line is hazard estimate enclosed within 68% CLs.

6. Fig 5
Predicted 1-year freedom from reoperation according to age at mitral valve repair. Graph is a nomogram of multivariable equation represented by Table 3, with blood urea nitrogen set to 17 mg/dL, hematocrit to 40%, and posterior wall thickness to 1.1 cm. Solid line is parametric estimate, and dashed lines are 68% confidence limits equivalent to ± 1 standard error. Note expanded scale.

Temporal trend in return of postoperative mitral regurgitation (MR). Squares = no MR, open circles = 1+ MR, closed circles = 2+ MR, triangles = 3+/4+ MR.
