Fig 4.

Comparison of postoperative change in coaptation length (and area). Shown here is net change in coaptation length (postrepair coaptation length compared with prerepair coaptation length) versus normalized intercommissural position for both the saddle-shaped (dashed) and flat (black) annuloplasty groups. Notice an increase in coaptation length (and area) across the entire intercommissural distance for the saddle group (especially toward the posterior commissure [PC]) and a decrease in coaptation length (and area) across the entire intercommissural distance for the flat group (especially toward the PC). (AC = anterior commissure.)
