Key result
The 'Hornet' technique provides a less challenging method to accurately adjust or shorten Gore-Tex artificial chordal length during mitral valve repair when revision is needed.
Why the study?
In mitral valve repair, the height of newly placed Gore-Tex sutures often requires correction to improve leaflet coaptation or correct systolic anterior motion, but reinserting new chords with an annuloplasty band in place is technically challenging.
Describes a surgical technique to adjust artificial chordal length during mitral valve repair when revision is needed after annuloplasty band placement.
New "Hornet" technique enables Gore-Tex chord adjustment in mitral repair; leaves open durability and SAM outcomes versus established methods.
Often times, in mitral valve repair techniques, the height of the newly placed Gore-Tex sutures needs correction to achieve better mitral valve leaflet coaptation or to correct systolic anterior motion (SAM). Herein, a less challenging "Hornet" technique to accurately adjust artificial chordal length is described. This technique describes a way to adjust/shorten the Gore-Tex chords, should they need revision. Ideally, this should not be needed, however due to the circumstances for mitral valve repair, this is sometimes necessary. With the annuloplasty band already in place, it is somewhat harder to reinsert new chords and hence, this technique may be beneficial.

Alameddine et al. (2019) studied Mitral valve repair. Hornet technique was evaluated. The 'Hornet' technique provides a less challenging method to accurately adjust or shorten Gore-Tex artificial chordal length during mitral valve repair when revision is needed.
