Key result
A simple method using a slit plastic tube allows the knot of premeasured artificial chordae to be tied securely without changing the intended length during mitral valve repair.
Why the study?
Does a slit plastic tube technique ensure the correct length of artificial chordae during mitral valve repair?

May aid precise chordal length in mitral repair; leaves open validation in outcome studies.
Excellent long-term results have been described for replacement of diseased mitral valve chordae with polytetrafluoroethylene sutures. Tying the knot at the intended length of the artificial chordae is technically demanding. Herein, a simple and reproducible method, using a slit plastic tube for stenting the artificial chordae at the intended length is described. With this technique, the knot of the premeasured artificial chordae can be tied surely without change in the length.
