Pre-Measured Artificial Chordae for Mitral Valve Repair

There is growing interest in the application of artificial chordae to correct mitral valve regurgitation caused by prolapse. Application of pre-measured artificial chordae facilitates creation of chordae of appropriate length. Herein we illustrate the technique for creation of pre-measured artificial chordae, documenting neo-chordal length and number in 50 patients with anterior leaflet prolapse, highlighting the need for chordae of more than one length in 14% of patients.
