Adjusting the neochords height for better leaflets coaptation following mitral valve repair
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.
