Double-leaflet Technique for Mitral Regurgitation With Small or Tethered Posterior Leaflet.

Abstract

Small leaflets make mitral valve repair procedures challenging. Our double-leaflet technique creates a new autologous pericardial leaflet attached to the papillary muscle, annuloplasty ring, and neighboring scallops above the small or tethered posterior leaflet. This simple additional technique provides deep coaptation after mitral valve repair for both degenerative and functional mitral regurgitation with the small or tethered posterior leaflet.
