A technique is described for correction of mitral regurgitation when the posterior leaflet has a reasonable length (approximately 10 mm), but its movements are limited by thickened and short chords. To avoid further retraction when a band or a ring is positioned to force leaflets coaptation, native chords are replaced by artificial chords (leaving 10 mm of extra length), which are then cut. In 6 patients, after 6 months of follow-up, the results are good. © 2011 The Society of Thoracic Surgeons.

Abstract
A technique is described for correction of mitral regurgitation when the posterior leaflet has a reasonable length (approximately 10 mm), but its movements are limited by thickened and short chords. To avoid further retraction when a band or a ring is positioned to force leaflets coaptation, native chords are replaced by artificial chords (leaving 10 mm of extra length), which are then cut. In 6 patients, after 6 months of follow-up, the results are good. © 2011 The Society of Thoracic Surgeons.File in questo prodotto:
