title: Intracardiac calipers for artificial chordae replacement in mitral valve repair.
abstract: Length adjustment of artificial chordae is crucial in the outcome of anterior mitral valve repair. Herein, a simple and reproducible method of artificial chordal replacement using polytetrafluoroethylene suture is described. With this technique, the length of the neo-chordae is easily decided and the knot can be tied surely without change in the length using only one instrument.
