Placement of Neochords in Mitral Valve Repair: Enhanced Exposure of the Papillary Muscles Using a Standard Valve Sizer.

Abstract

Minimally invasive mitral valve repair with placement of artificial chordae for mitral valve regurgitation has become the standard of care. In some cases, such as Barlow's disease or bileaflet prolapse, papillary muscle exposure may be difficult. By using a valve sizer to retract both leaflets, visualization can be optimized, thus simplifying suture placement and thereby minimizing cross-clamp and cardiopulmonary bypass times. This technique is simple, is cost effective, and can be applied quickly.
