2. Fig 1
Timing of reoperation for repair failure after mitral valve repair for degenerative disease according to mechanism of failure. Patients having both procedure-related (top line) and valve-related failure (bottom line) appear twice in these graphs. Cumulative distribution of times to failure is shown with each step representing a failure. The median time to failure is the point at which each curve crosses the 50% line.

3. Fig 2
Re-repairs versus valve replacement for repair failure after mitral valve repair for degenerative disease by date of reoperation. Solid circles represent means by yearly groupings and the solid line is a trend line. (A) Overall results. (B) Results stratified by mechanism for repair failure. Patients experiencing both procedure-related (top line, filled circles) and valve-related mechanisms (bottom line, open circles) of failure appear in both strata.

Freedom from reoperation after mitral valve re-repair (line). Each solid circle is a reoperation, vertical bars are asymmetric confidence limits equivalent to ± 1 standard error, and numbers in parentheses patients are remaining at risk.

5. Fig 4
(A) Risk-unadjusted overall survival after mitral valve (MV) reoperation for repair failure. Each open circle represents a death, vertical bars are asymmetric confidence limits (CLs) equivalent to ± 1 standard error, and numbers in parentheses are patients at risk. Solid lines are parametric estimates enclosed in CLs equivalent to ±1 standard error (dashed line). (B) Unadjusted survival stratified by approach to reoperation (repair [top set of lines] versus replacement (bottom set of lines]). Filled circles (repair) and open triangles (replacement) represent a death, vertical bars are asymmetric confidence limits (CLs) equivalent to ±1 standard error, and numbers in parentheses are patients at risk. Solid lines are parametric estimates enclosed in CLs equivalent to ±1 standard error (dashed lines).
