A New Device for Ensuring the Correct Length of Artificial Chordae in Mitral Valvuloplasty

Mitral valvuloplasty using Gore-Tex as artificial chordae, especially for patients with anterior leaflet prolapse, is often associated with difficulties in determining the length of artificial chordae as well as in preventing knot slipping. We describe a simple technique of using a new device that enables surgeons to easily determine the accurate length of the artificial chordae and to tie the slippery knot without sliding and damaging it.
