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. (J Card Surg 2010;25:737‐739)
