Chordal relocation for repair of anterior mitral leaflet flail: a reproducible option.

Repair of anterior mitral leaflet (AML) flail is considered to be among the more technically challenging mitral procedures. While neochord reconstruction is an excellent technique, sizing challenges may limit wide reproducibility. Chordal relocation of secondary or tertiary AML chords can minimize sizing imprecision in open or minimally invasive repair while providing patients with a safe, durable and reproducible option. Native chords can be readily released and re-implanted from positions in the body of the leaflet to provide primary AML support, provided there is preservation of ipsilateral papillary muscle alignment. We illustrate the sole use of this reproducible method to repair AML flail.
