Simple Chordal Replacement With a Newly Designed 'Mitral Plate' in Mitral Valvuloplasty

Mitral valvuloplasty using GORE-TEX as the artificial chordae is often associated with difficulties in determining the length of the artificial chordae, achieving the correct artificial chordae length, and preventing knot slippage, especially for beginners. We describe a simple technique involving a novel device called the "Mitral Plate," which enables surgeons to automatically determine the correct length of the artificial chordae and tie slippery knots without performing excessive saline tests.
