Repair of congenitally absent chordae in a tricuspid valve leaflet with hypoplastic papillary muscle using artificial chordae.
Isolated congenital tricuspid regurgitation without downward displacement of the leaflet is uncommon in adults, and repair of such valves often requires a procedure that is more complex than simple tricuspid annuloplasty. We describe a technique of tricuspid valvoplasty using the neo-papillary loop technique to reconstruct multiple artificial chords for isolated congenital tricuspid regurgitation associated with a dysplastic anterior leaflet with agenesis of the chordae tendineae and a hypoplastic anterior papillary muscle. This technique provides a simple and valuable option for the repair of dysplastic valves lacking chordae, even those with a hypoplastic papillary muscle.
