Repair of Severe Tricuspid Regurgitation in a Neonate With Intrauterine Tricuspid Valve Chordae Tendinae Rupture

Congenital tricuspid valve regurgitation (TR) is rare, and chordae tendinae rupture is an even more uncommon finding in neonates. We describe a case with intrauterine tricuspid valve chordae tendinae rupture leading to severe TR and hydrops fetalis. Successful tricuspid valve repair using artificial chordae, leaflet approximation, and annular reduction were used as rescue therapy for the neonate.
