Mitral valve repair in Barlow's disease by chordal reconstruction using the adjustable slip-knot technique

The adjustable slip-knot technique-a procedure for facilitating repair of the mitral valve prolapse-was first performed and reported by us in 2015. This technique comprises six steps: anchor institution in the papillary muscle, flexible band positioning, saline injection to confirm the prolapsing site, neochorda setting between the anchor and leaflet, fine adjustment of the neochordal length, and knot-fixing to confirm repair. Here, we have described the first case of successful mitral valve repair using the adjustable slip-knot technique in a 51-year-old man with Barlow's disease.
