Abstract

For adults, the standard procedure for mitral valve repair of Carpentier classification type II mitral regurgitation is reconstruction with artificial chordae. In children, placement of artificial chordae of precise length between the papillary muscle and prolapsed mitral leaflet in the restricted mitral subvalvular space is technically difficult. We successfully performed mitral valve repair in 3 pediatric patients using a modified fixed loop-in-loop technique.
