This Mitral Foundation Teaching Library case is going to demonstrate teaching points in the repair of multi-segment Barlow's mitral valve disease.

When you have a multi-segmented Barlow's, rather than cut out the tallest segment, sometimes you want to do a targeted resection of a less tall segment using the indentation as one side of your resection. Then, when you detach the tall segment and perform a sliding leaflet plasty, you'll see that you really preserved the maximum amount of leaflet for coaptation and that you can do this without creating any tension on the suture lines and avoid the need for angular annular compression.
